About

CV

Activities:

I am the chair of the prize committee for the Abel Prize for the period 2023–2026. I was the Principal Investigator of the research project ("Toppforsk") Waves and Nonlinear Phenomena (WaNP). I was the Secretary General of the International Mathematical Union (IMU) for the period 2015–2022. On the occasion of my 60th anniversary in 2016 the conference Non-linear PDEs, mathematical physics, and stochastic analysis was hosted here at NTNU. See proceedings Non-Linear Partial Differential Equations, Mathematical Physics, and Stochastic Analysis, European Mathematical Society Publishing House.  

Research areas:

Differential equations, mathematical physics; in particular hyperbolic conservation laws and completely integrable systems. Stochastic analysis and flow in porous media.

Teaching: 

Spring 2023:  MA8105 Nonlinear PDEs and Sobolov Spaces

Fall 2021:  TMA4305 Partial Differential Equations
