Degree and Student Projects
Astronomy and Space Physics
Astrophysics is the study of the behavior, physical properties, and dynamical processes of celestial objects and phenomena. Through its study one hopes to understand the formation and evolution of the universe and all its parts. Research at the department focuses on three main areas: our solar system, stars and their environments (including exoplanets), and galaxies and cosmology. The research aims to answer questions such as:
- How and where did the atoms and molecules that make up our galaxy, our solar system and our planet form?
- What do they tell us about the early universe and the Big Bang?
- How do stars and planets form and evolve?
- Is our solar system special?
- How did stars and galaxies early in the universe differ from those today?
- How did they affect the evolution at later times?
There is a range of possible bachelor- and master projects in astrophysics related to these fields of research. We have assembled a list of researchers able to supervise projects with a short description of their fields of research and interests. Please feel welcome to contact any or all of them to discuss possible projects.
Stellar Spectroscopic Models
I work on making accurate models of the light that emerges from stars like the Sun, that take into account the effects of convection in stellar atmospheres, as well as departures from local thermodynamic equilibrium. By comparing these models against real observations of stars, it is possible to infer essential properties of the stars – in particular, their chemical compositions. To a good approximation, the present-day chemical compositions of Sun-like stars reflect the compositions of the gas from which the stars formed at their respective times of birth. Thus, by studying stars of different ages and different orbits in this manner, it is also possible to learn about the history and evolution of our Galaxy and the cosmos.
I can offer projects with an emphasis on theory (understanding the physics of spectral line formation in the atmospheres of Sun-like stars), computations (developing and implementing algorithms for scientific codes; running these codes on clusters or supercomputers), and data analysis (quantitatively comparing these spectroscopic models against observational data; interpreting the results in an astrophysical context).

Stellar magnetic fields
Observations of the Sun demonstrate that stellar surfaces are far from being quiet, stable environments. Stars have rapidly evolving magnetic field and spots. They vary on many time scales, from minutes (pulsations) to decades (activity cycles). My research is focused on observing these phenomena and building theoretical models of stellar magnetism, variability, and activity, with important implications for stellar physics, effects on terrestrial climate, formation of planetary systems and the origin of life.
I offer a range of projects in studies of stellar variability, magnetic fields, and star spots. This work is coupled with our ongoing research using state of the art space instruments and largest ground-based optical telescopes.

Stellar spectroscopy
My research focuses on low-mass stars like the Sun, in particular the outer layers from which we receive stellar photons. This starlight tells us how hot and heavy such stars are and what they are made of. As low-mass stars live for billions of years, they allow us to study the chemical history of the Milky Way. We may ultimately learn when and where the elements were produced that form the basis for complex life.
I offer various projects in quantitative stellar spectroscopy, often combining advanced modelling with observations from the largest telescopes (VLT, Keck).

Meteor observations / Space Situational Awareness (SSA)
During a dark night one often spots fast-moving objects. Some of these are caused by meteoroids entering the atmosphere, and others are due to man-made satellites. In order to understand and monitor these phenomena, several camera networks across the globe perform continuous observations of the night sky. One of these networks is the Swedish Allsky Meteor Network, active since 2015 and coordinated from Uppsala.
I offer several projects related to this network, which include studies of meteors, meteor showers and/or satellites. These projects can be adapted to individual interests, and may, among others, include instrument development, calibration, automated image analysis, and orbit determinations.

Terrestrial planetary atmospheric modeling
The 3-D modeling of terrestrial exoplanetary atmospheres is critical to determining whether they reside in the habitable zone or not. We use knowledge about solar system atmospheres through time (Venus, Earth, Mars) to validate such models. We have successfully modeled the atmospheres of Proxima Centauri b, planets in the Trappist system and other hypothetical systems using ROCKE-3D. ROCKE-3D is an open source 3-D General Circulation Model whose development I lead. Together we can learn how models operate, their limitations, and how they can better inform us about the hypothetical atmospheres of exoplanetary worlds and even the ancient worlds of Venus, Earth and Mars in our own solar system. Previous Bachelors projects include looking at simulations of Proxima Centauri b, and the climate of a world with variable eccentricity.

Projects within space and plasma physics
We investigate what goes on in space using instruments we build ourselves and fly on spacecraft, ground based instruments, computer simulations and plasma theory. Also, we focus on the study of the basic small- and large-scale processes and fundamental physical principles which control the Earth's interaction with its space environment. Of particular interest are linear and non-linear dynamical processes involving space plasma and the associated exchange of energy, linear momentum, and angular momentum between plasma and radiation.

X-ray Photon Science
Eco-friendly Defect Passivation in 2D Semiconducting Materials
Since the 2010 Nobel Prize in Physics, related to the monolayer two-dimensional (2D) material graphene, the interest in similar materials has grown markedly. The discovery of 2D semiconducting materials based on transition metal dichalcogenides (TMDs), with the chemical structure MX2 (M=Mo, W; X=S, Se, Te), has opened up new interesting possibilities in optoelectronic devices, since they possess excellent properties well suited for optoelectronic applications, like high extinction coefficients due to the strong excitonic effects, exceptional mechanical properties, as well as chemical and thermal stability, to highlight a few. In this project, we will develop eco-friendly chemical treatments to passivate the defects of 2D materials, investigate the effect with photoluminescence and Raman measurements, and charge transport measurements. We will also develop the mechanistic picture for the defect passivation with X-ray spectroscopy.

Probing charge dynamics in liquids with THz spectroscopy
%20image2.png)
The movement of charge is the basis of a wide range of fundamental processes in molecular physics, catalysis, biology, and materials science. Photo-excitations, the formation and breaking of chemical bonds as well as electron and proton transfer all involve delicately balanced movements of charge between different atoms and along specific molecular bonds. In our group, we are developing new spectroscopic methods based on ultrashort THz, optical and X-ray pulses to study charge dynamics in molecular processes with relevance in catalysis and light-harvesting. In this project, we will use single-cycle THz pulses generated from a femtosecond laser source to study the response of the solvent environment to the charge-transfer excitation of a transition metal dye. We will investigate how such an impulsive change of the molecular charge distribution interacts with the electric field of the surrounding polar solvent to understand the long-range charge propagation effects in homogeneous liquid environments following the creation of confined molecular electron-hole pairs.

Seeing the making and breaking of chemical bonds with X-ray spectroscopy
Molecular bond breaking and bond formation are at the heart of molecular transformations. Understanding how to manipulate chemical bonds by breaking and making them in small and unreactive molecules such as in methane or carbon dioxide is of utmost importance for sustainable societies. This fundamental challenge in catalysis research is the basis for functionalizing the unreactive molecules into valuable compounds such as methanol. In our group, we perform time-resolved X-ray spectroscopic experiments at large-scale facilities like X-ray synchrotrons and X-ray lasers to follow such chemical reactions in real time of molecular transformations. In this project, we will investigate how specific homogeneous transition-metal catalysts mediate molecular transformations of small molecules. We will investigate how orbital interactions evolve on the relevant timescales from femtoseconds to microseconds and how they help breaking and making molecular bonds.

Simulating fundamental processes in chemical reactions
.png)
Theoretical modelling of a chemical reactions often offers a unique way of understanding the fundamental properties that drive it. Most chemical reactions can be simply understood in terms of changes of electronic configuration and motions of nuclei. Computational studies involving quantum-chemical approaches hence have a very high degree of success in giving new and comprehensive insight. In our group, we focus on finding new ways to use time-resolved X-ray spectroscopy to understand chemical reactions at the level of atoms and electrons and for interpretation of the X-ray spectra we use quantum-chemical simulations. In this project we will simulate the time-resolved X-ray spectroscopic signatures for the photo-initiated dynamics in transition-metal complexes at the TDDFT, ROCIS and RASSCF level of theory. Furthermore, excited state molecular dynamics and reactivity simulations of such photochemical processes will also be explored. We will learn what it is that drives the reaction with the aim to find rules for how to best convert sunlight into new molecules.

Fundamental Processes in Liquids
Our research addresses questions that are at the very basis of e.g. atmospheric chemistry, biophysics and our renewable energy related projects. This work focusses on intermolecular interactions in liquids (e.g. hydrogen bonds in water) and how they react to changes of the system like the solution of salts or varying temperatures. We aim to understand how such changes take effect on the molecular level and the tool for our investigation is photoelectron spectroscopy. This technique allows us to obtain spacial and temporal information about our samples. Thus we can investigate the surface propensity of solutes in a liquid or investigate dynamics on a femtosecond timescale. Since we strive for a holistic understanding, we also combine our experiments with investigations on clusters or molecules in the gas phase.
Our experiments usually take place at the synchrotron light sources SOLEIL, Paris (France), BESSY, Berlin (Germany), MAX IV, Lund (Sweden) or LNLS / SIRIUS, Campinas (Brazil). During the experiments we work closely together with scientists from other institutions with diverse scientific backgrounds.
Interested students ideally have a background in chemistry, physics or a related subject and should be open to acquire knowledge from other scientific fields since our projects often use methods from physics applied to questions motivated from chemistry.

Biophysics and Biochemistry
Our group addresses how biological processes work on the molecular scale and we employ photoelectron spectroscopy to obtain the desired, molecular-level information. Currently, we are working on two main topics:
- Radiation-induced damage to biologically relevant molecules
- The surface propensity of organic molecules in aqueous solutions
Radiation-induced damage
Whenever we travel in high altitude (e.g. flying in a plane) or receive an X-ray of the skeleton, we are subjected to radiation induced damage. If high-energy photons interact with matter they can trigger a multitude of reactions we currently lack detailed knowledge of. Consider two cases: A photon hits a biomolecule directly and ionizes it. The molecule may either dissociate directly or undergoes further relaxation and then breaks apart. Which of the two cases takes place? That is determined by which molecular level has been initially ionized and the structure of the molecule. However, we are currently not able to predict precisely which parameters favour one over the other process and that’s what our research focusses on.
Surface propensity of molecules
The biological relevance of the second aspect of our research, the surface propensity of biomolecules, becomes apparent when considering all the interfaces between aqueous solutions and e.g. protein surfaces or cell membranes in the body. We try to learn under which conditions ions and molecules are either repelled or drawn to these interfaces and what the driving forces for these dynamics are. By understanding these, we contribute to resolving questions about e.g. protein folding and the transfer of molecules through membranes. This aspect of our research is closely related to the fundamental properties of solutions, which is another one of our research topics.
We use synchrotron light sources in Europe and abroad for our experiments. The most commonly used synchrotron facilities by our group are SOLEIL (Paris, France), BESSY II (Berlin, Germany), MAX IV (Lund, Sweden) and SIRIUS (Campinas, Brazil). The research projects are carried out in collaboration with other researchers from all around the globe and with very different scientific backgrounds. Therefore, interested students should be open to acquire knowledge from other scientific fields but their own as part of the project work and should have a background in biology, chemistry, physics or a related field.

X-ray spectroscopy of bimetallic complexes
%20image1.png)
Cooperative effects between two or more metal atoms are at the core of the high catalytic efficiency of metalloenzymes, with which nature facilitates important molecular transformations such as water splitting in photosynthesis as well as the production of methanol in methane monooxygenase. The metal-metal interactions introduce degrees of freedom such as metal-metal bond order and polarity, which are absent in monometallic systems and which strongly influence the reactivity of systems with two or more metal atoms. In our group, we use X-ray spectroscopy to investigate the chemical bonding in transition metal catalysts to understand the mechanisms with which they drive specific molecular transformations. In this project, we will use resonant inelastic X-ray scattering (RIXS) to investigate a series of model bimetallic complexes. We will spectroscopically characterize different metal-metal bonding configurations in an effort to gain novel insight into how metal-metal cooperativity influences catalytic reactivity and function.

Nanoscale Device Physics
Overall theme
Device physics forms the foundation for modern day electronic marvels. Understanding the charge and spin transport, their manipulation in new functional materials is key to the future electronic devices, energy and sensing applications. Nanoscale device Physics is an exciting area of research, where we fabricate nanoscale devices with innovative designs, through state-of-the-art nanofabrication techniques in cleanroom and perform charge/spin transport experiments to uncover the prospect of novel materials and their devices for future applications. The following is a brief outline of the current projects.
Novel graphene spintronic devices
Experimentally realized in 2004, graphene, a one atom thick crystal of carbon atoms placed in a honeycomb lattice, is a material with superlative properties and holds promise for next generation electronics. Spin of electrons, a quantum mechanical property, is responsible for magnetism in solids and forms the basis for an evolving field called ‘Spintronics’. Most successful existing applications of spintronics are the high capacity memory storage devices such as hard disks and MRAM. Research in spintronics is a way for future low power, faster electronic devices. Graphene is prime to spintronics, because it is the best known material for transporting spin information of electrons over long distances. It is anticipated to play a major role in the future of spin based devices in electronics. In this project, our aim is to investigate new spintronic devices of graphene with an aim to enhance their performance with novel device schemes like graphene devices on new substrates that have never been explored before.
Charge and spin transport in new 2D crystals
Two dimensional crystals (2D) are a new class of materials which show special properties for their confined geometry. These crystals are like atomic planes pulled out of bulk crystals having layered structure (stacks of 2D crystals). Graphene, an atomically thin semi-metal is one such crystal that is widely studied and reported in the last decade. In addition, there are semiconducting crystals such as MoS2, WS2, Black Phosphorus which are promising for future transistors, insulating crystals such as h-BN, Fluorographene promising for substrates and tunnel barrier applications, and there are other crystals with exotic properties like topological insulators such as Bi2Se3, Bi2Te3 etc. The number of materials in the 2D crystal library is increasing continuously, making the field a lot to be explored. In this project, going beyond the existing crystals, we will investigate the charge and spin transport in new/emerging 2D crystals that show long term promise for applications in nanoelectronics and spintronics.
Magnetic domain wall based devices
A magnetic domain wall separates two domains (regions in space having different directions of magnetic moment) of magnetization in a magnetic material. In the past decade a significant understanding has been developed about the manipulation of domain walls using charge or spin current and their prospect for memory and logic applications. It is now possible to engineer magnetic nanostructures with specific magnetic orientation and domain walls, which can be further manipulated by external magnetic, electrical or optical stimulus. In spite of previous developments, there is plenty of room for new developments that can form the basis for newer technologies. In this project, our aim would be to engineer magnetic nanowires with domain walls, image the domain walls using Magnetic force microscopy and manipulate them using charge and pure spin currents. The nanowires will be fabricated using the state of the art e-beam lithography technique at the Ångström Microstructure Laboratory, which will be followed by the said experiments. In the next step such magnetic structures will be integrated with non-magnetic spin current carriers such as aluminum or graphene nanowires in pursuit of novel spintronic devices.

Molecular dynamics of organic molecules on water surfaces
Abstract
The behavior of small organic molecules on water surfaces is important for atmospheric chemistry. Molecules that show surface preference have a larger possibility to interact with the surrounding atmosphere. We have studied how small organic molecules such as carboxylic acids and alcohols behave in a water/gas interphase both experimentally and using molecular dynamics. This project is focused on doing a simulation study of how the structure of different organic molecules affect the molecules' surface preference. Simulations will be done using the molecular dynamics package GROMACS and will be strongly connected to experimental results from studies at synchrotron sources such as MAXlab.

High-resolution imaging of single particles using X-ray Free Electron Lasers by reducing the background scattering of gases
Structure solution from single particles such as proteins is the holy grail of structural biology. This was one of the goals in mind during the development of X-ray free electron lasers (XFELs). XFELs with their intense brilliance and pulse length on femtosecond scale mean a paradigm shift for structural biology.
Image source: Henry Chapman, CFEL. Science, 2007, 316, 1444-48.
So far high-resolution single particle imaging (SPI) has not been achieved. Compared to other methods, SPI suffers from low signal intensity, which is determined by the sample properties and the XFEL parameters. In order to improve the signal to noise ratio the sample environment must be improved. With our current setup, an electrospray aerosolizer used for sample delivery in combination with the ‘Uppsala injector’, we are able to deliver particles of 70-2000 nm diameter into the XFEL-beam.
The project aims at reducing the background noise created by various gases used for aerosol injection, by using specially a designed capillary head to reduce the mass flow of sheath gases required to maintain a Taylor cone. And to track particles down to 20 nm using Rayleigh-scattering microscopy as they exit the injector.
Interested students ideally have a background in engineering, physics or a related field and have some knowledge of coding in Python not compulsory. Also, should be open to acquire knowledge from other scientific areas since our projects reach across the borders of traditional scientific subjects.

Instrumentation and Accelerators
Water Cherenkov Test Experiment
Master Thesis project at CERN, Geneva, Spring 2025
A Water Cherenkov Test Experiment (WCTE) is being prepared at CERN by an international WCTE Collaboration with the purpose of studying in detail the final state particles electrons, muons, pions, protons, neutrons and gammas in the interactions of neutrinos with water in Water Cherenkov Detectors in neutrino-oscillation experiments like T2K in Japan, that planned for Hyper-K in Japan and that planned for ESSnuSB in Lund and in Zinkgruvan near Askersund in Sweden (see in particular the videos accessible at this site which give an overview of the planned ESSnuSB experiment).
The final state particles will be detected and identified in a 50 m³ water tank equipped with photo multiplier tubes on its inside walls that will measure the Cherenkov radiation generated by the different kinds of beam-particles in in the water.
The Uppsala Group in the WCTE Collaboration has in particular contributed to the build-up and tests of the system that provides the ultrapure water used as radiating medium in the Cherenkov detector and the addition of Gadolinium in the water for enhanced neutron detection-efficiency.
The Master Thesis project will consist in taking part in the preparation and data taking of the experiment in the t9 secondary beam from the Proton Synchrotron in the East Hall at CERN during the spring of 2025 and the analysis during and following the data taking. A particular feature to be tested in the run in the spring will be the project to mix in Gadolinium in the Cherenkov-detector water.

Electro-magnetic design and analysis of LEnuSTORM magnet system
Superconducting magnets are the backbone of circular accelerator technology, and they are responsible for steering and focusing the particle beams inside an accelerator. In this thesis project, the student will be responsible for performing a parametric study on a unique magnet system especially designed for LEnuSTORM.
LEnuSTORM is a racetrack storage ring which will became a component of the European Spallation Source neutrino Super Beam (ESSνSB) experiment. The racetrack will store muons, and the muon- and electron-neutrinos, that result from muon decays, will be used to create a beam to measure neutrino cross-sections and look for sterile neutrinos.
The strong anisotropy of the storage ring is what makes this racetrack unique. Because LEnuSTORM produces useful neutrinos in its straight sections, the racetrack curves must be as short as possible to minimize muon waste. As a result, LEnuSTORM magnet system, used to store and steer the muon, must be compact and optimized.
The goal of the student will be to model the magnet system of the racetrack using the dedicated software RAT-GUI and to study different electro-magnetic configurations. The student will gain knowledge of superconducting magnet technology throughout the project, and the outcomes will be published in a scientific journal.

Expulsion of magnetic fluxes in type-II superconductors upon the transition from a normal- to superconducting state
If a type-II superconductor is exposed to an external magnetic field upon the transition from a normal- to superconducting state, then the magnetic field gets trapped in the material and the performance of the superconductor degrades. Specifically, the residual resistance of the superconductor, which is a measure of resistance to alternating currents, decreases. In the applications of type-II superconductors such as superconducting accelerating cavities, it is vital to have the residual resistance as low as possible to minimize the heat load produced by accelerating fields in the cavity. In this project, you will study experimentally and theoretically the novel phenomenon of expulsion of magnetic fluxes by the moving superconducting phase front during fast cool down of superconducting cavities.

Coupling of slow waveguide modes to surface plasmons of a subwavelength wire
We are developing a new technique of testing accelerating cavities, in which a subwavelength wire is used to mimic a beam of charged particles. The accelerating field of the cavity couples to surface plasmons of the wire and the electromagnetic energy is transferred from the cavity to the outside world via the wire resembling the process of particle acceleration. In the project you will perform analytical calculations of plasmonic modes of the subwavelength wire, run computer simulations with the professional software ‘CST Microwave Studio’ to study the coupling of cavity modes to the plasmonic modes and participate in experimental verification of the result in our microwave laboratory.

Diffraction of single-cycle THz pulses
THz radiation is becoming increasingly important in several areas of physics, chemistry and biology because its spectral range corresponds to numerous collective excitations in multiatomic systems such as molecular rotations, DNA dynamics, spin waves, Cooper pairs and so forth. Strong single-cycle THz pulses allow engineering new dynamic states of matter and one of the spectacular examples of using THz radiation for controlling the properties of materials is the THz light-induced superconductivity. If you like mathematical challenges, then this project is for you. We will tackle the problem of diffraction of single-cycle THz pulses in free-space. Specifically, the simulations show that the spatial diffraction "results in the differentiation of the temporal profile" of a single-cycle pulse so that the pulses becomes a quasi-half-cycle. In the project we will look into the math and physics behind this phenomenon.

RF power measurement at FREIA
At the FREIA Laboratory, the general focus is on developing particle accelerator technology that later could be used in large research facilities, such as CERN, European Spallation Source (ESS)... We are presently developing a 10 kW RF power amplifier based on solid state transistors. Each transistor needs a dedicated monitoring. The work consists in developing the RF power measurement, using a SWR meter or VSWR (voltage standing wave ratio) and the Arduino microcontroller.

Electro-acoustic stability of superconducting accelerators
The purpose of an accelerating cavity is to accelerate charged particles when they traverse the cavity. Acceleration is realized through a longitudinal electric field. One can imagine the acceleration of particles as surfers riding on an ocean wave. However, there is number of physical effects that make the cavity operation difficult. One of the negative effects reducing the stability of the excited field is the deformation of cavity walls caused by an electromagnetic pressure, a so-called Lorentz force detuning. Collisions of photons with cavity walls create such pressure determined by the Poynting vector. The project is devoted to studying mechanical oscillations of a superconducting cavity caused by the Lorentz force detuning and methods of its prevention.

RF Breakdown studies for CLIC
After the successful start of the LHC accelerator at CERN, we expect many years of discoveries that could lead to better understanding of the universe. Accelerator physicists however continue to plan for future facilities where more detailed studies of particle physics secrets can be done at higher energies. CLIC, the Compact Linear Collider, is the proposed successor to the LHC. In the CLIC particles are accelerated by a very strong electric field. Unfortunately, large electric fields can lead to vacuum discharges which in turn can affect the particle beam and lead to reduced performance of the CLIC accelerator. Studies of the physics behind vacuum discharges and its effect on the beam is therefore an important issue we are investigating in Uppsala.
In this project, students will learn how to manage experimental signals in large data sets stored by the logging system. The signals must be synchronized, analysed and correlated in a data analysis program to determine what physical processes occur during the discharge. The results of these measurements will contribute to the development of theory and verification of accelerating structures by providing information about the kinematics of charged particles inside the accelerating structure.
