About me

 

I am an associate professor (Docent) of Computational Mathematics at Department of Mathematics. My research interest is to develop and apply statistical and computational methods to understand how biophysical systems work. My focuses are on the interplays between information theory, data science, machine learning and statistical physics. I also teach and supervise in Mathematical Statistics.
