# Carles Batlle-Arnau

### Biosketch

I was born in Vilanova i la Geltrú (Catalonia) in 1961. I graduated in Physics in 1984 from Barcelona University, and received the Ph.D. degree in Theoretical Physics in 1988 from the same institution, under the supervision of Professor Joaquim Gomis. I was a post-doc fellow at the Physics Department of Princeton University from September 1988 to august 1989, and entered the Universitat Politècnica de Catalunya – BarcelonaTech (UPC) in 1989 as a lecturer. Since 1993 I am an Associate Professor with the Department of Applied Mathematics IV of the UPC. I have taught several first and second year applied mathematics courses for engineering students, as well as courses for mathematics and physics engineering students, and control theory courses for graduate students.

### Research lines

Energy-based modelling and control of complex systems, such as electromechanical systems and fuel cells, model order reduction of systems, and symmetries in classical and quantum systems.
