Research
We are focused in studying photosynthetic light reactions, in particular the water oxidation and proton coupled electron transfer in photosystem II. We use interdisciplinary approach combining a variety of biochemical, biophysical and spectroscopic techniques. Our primary method is Electron Paramagnetic Resonance Spectroscopy which is well suited to study the electron transfer reactions in biological systems.
