Lassi Paunonen

Associate Professor in Mathematics

My research develops mathematical theory for analysis and control of partial differential equations. The main focus is on deep and detailed analysis of challenging models arising from real-world applications.


I am an Associate Professor in Mathematics and the leader of the Systems Theory Research Group at Tampere University, Finland.

My research focuses on the following topics:
