The central theme of my research is multilinear phenomena in analysis and related areas. Many concepts in mathematics, from boundary value problems in partial differential equations and mathematical physics to finite point configurations in geometric combinatorics, are fundamentally tied to various operator bounds. This frequently leads to the estimation of linear and multilinear integral operators using techniques from harmonic analysis, often combined with geometric and combinatorial principles. With my collaborators I studied multipoint configuration versions of the Falconer distance problem, which can be thought of as a continuous analog of the well known Erdös distinct distance problem. Such point configuration problems have direct connections to big data. A key ingredient in our proofs were estimates on multilinear analogues of linear generalized Radon transforms. Apart from having these sort of applications to geometric measure theory and combinatorics then further investigation of the multilinear generalized Radon transforms has shown applications to restriction theory, partial differential equations, Sobolev trace inequalities and multilinear analogues of Stein's spherical maximal operator theorem. In my thesis and later work with collaborators I have used timefrequency analysis to study both L^{p} estimates and variational estimates for singular integral operators. Such operators are frequently motivated by, and have potential applications to, both nonlinear partial differential equations and ergodic theory. In addition, I have begun exploring additive number theory and have a recent paper on that topic that obtains bounds on sumsets.
