Bruno Vergara

Welcome!

I am postdoctoral researcher in the PDEs group at Universitat de Barcelona. Previously, I was a postdoc at University of Zurich and a graduate student at ICMAT (Madrid). My research interests lie in partial differential equations, with an emphasis on problems in fluid mechanics, dispersive and elliptic equations, geometric analysis and mathematical physics.

Research

Currently I am working on different questions in partial differential equations (PDEs) including:

  • Free boundary problems, elliptic and non local PDEs.
  • Carleman estimates and quantitative uniqueness for waves.
  • Singular and low regularity solutions to equations in fluid mechanics.

    Also, during my PhD I studied observability properties of geometric evolution equations via Carleman inequalities, conformally covariant operators and also certain models of shallow water waves with singular behavior. You can check out my thesis "Weighted inequalities in Fluid Mechanics and General Relativity" supervised by Alberto Enciso (CSIC-ICMAT).

    Although the aforementioned problems arise in very different contexts, at some extent they share some basic analytical techniques to deal with singularities and often involve the study of non local operators.
