Short presentation
I am a researcher in the Pharmacometrics research. I graduated in 2021 and my PhD supervisors were Maria Kjellsson and Bengt Hamrén. My current research interests are to develop methods and models for analysis of composite scale data, which are common in for example neurodegenerative disorders and CNS disorders.
