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.

Experience

Lately

I am Assistant Professor (RTdB) at UNIMORE - DSMI, Modena and Reggio Emilia (Italy)


Previously

I was a Postdoc Researcher at

I was also a Visiting Researcher at

I got a PhD in Computer Science, Mathematics and Physics at


My CV

Research

Ongoing projects

  • Boundary value problems with indefinite weights
  • System of coupled equations with degenerate diffusion
  • Reaction-convection-saturated diffusion models
  • Reaction-diffusion models with transmission conditions
  • Discrete-time population models for threshold harvesting
