Currently associate professor (professor agregat) at Universitat Autònoma de Barcelona. I my Ph.D. in UAB under Xavier Tolsa's tuition, on Calderón-Zygmund operators and Sobolev spaces on domains, with applications to quasiconformal mappings. After that I have been postdoc in UAM with Daniel Faraco and in Aalto Yliopisto with Kari Astala, working on the Calderón inverse problem with techiques of quasiconformal mappings. We could develop a characterization for the sets of conductivities where the inverse mapping is continuous. I also obtained a postdoc position and a JdC-I position in UAB with Xavier Tolsa to work on free boundary problems, reaching remarkable results on the thin one-phase free boundary problem and in the VMO two-phase problem for harmonic measure. Actually I am working in harmonic measure problems with Xavier Tolsa and our Ph.D. student Ignasi Guillén.
