Mateu, Joan

Associate Professor at UPC from 1990-1995. Associate Professor at UAB from 1995 until now. As a researcher I have proposed to solve problems that range from approximation questions for solutions of elliptic equations in different norms, problems on geometric measure theory related to the semiaditivity of analytic capacity, singular integrals, quasi-conformal mappings and in recent years I am mainly interested in problems related to the applications of harmonic analysis in fluid mechanics and in material sciences. In all these fileds I have obtained quite interesting results.
