Welcome

I am a professor at the Mathematics Department of Instituto Superior Técnico.

I am a geometer and my research interests include Poisson and symplectic geometry, Lie theory and integrable systems.

I belong to the Center for Mathematical Analysis, Geometry, and Dynamical Systems. I am Editor of PortugaliŠ Mathematica and an Associate Editor of Journal of Geometric Mechanics. I am a member of the executive committee of the European Mathematical Society.

***Please note that I have moved to the Department of Mathematics of the University of Illinois at Urbana-Champaign where I have assumed the position of Lois M. Lackner Professor in Mathematics. This webpage is no longer mantained. Please check my new webpage. ***
