Elisa Sovrano

Assistant professor (RTDB) @ UNIMORE

I am a researcher in nonlinear analysis. I work on boundary value problems associated with ordinary and partial differential equations, and on dynamical systems. My goal is to make applied models more understandable from a mathematical point of view.
