My research is concerned with Harmonic Analysis and the theory of singular integral operators. My main area of work is timefrequency analysis, initiated by Carleson with his celebrated result on the pointwise convergence of Fourier series for $ L^2 $ .
functions. Since then the field has been significantly developed and many deep and surprising connections have been found with Ergodic Theory, Additive Combinatorics, and, crucially, with the study of dispersive PDEs and SDEs. On the other hand, many fundamental questions in the area remain open and some are beyond the reach of currently developed techniques. Timefrequency behavior often arises when considering maximal or multilinear analogues of CalderónZygmund SIOs.
My PhD thesis (2016) was concerned with developing and applying outer measure Lebesgue space theory: a powerful and general functionalanalytic framework allowing one to systematically deal with with a large class of timefrequency operators.
