“In Mathematics, unlike elsewhere, wrong notions die off easily. Our capacity for understanding is hampered, foremost, by the inability to dispel false concepts.” – Alexander Beilinson

About me:

I am a mathematician. I completed my undergraduate studies at UFRGS (Porto Alegre, Brazil) in 1996, and my PhD at IMPA (Rio de Janeiro, Brazil) in 2001. I have previsouly had tenured positions on UFRGS and PUC-Rio. I arrived at PUC-Chile in 2014. My research focuses on Dynamical Systems and its relations to Geometry, Linear Algebra, and Control Theory.
