My research lies at the interface of harmonic analysis, geometric measure theory, and combinatorics, centered on understanding how the geometric and combinatorial structure of a set constrains the configurations of distances, areas, and other geometric quantities it can generate. Many such questions, from continuous settings in Euclidean spaces to their discrete and finite field analogues, can be reformulated as problems about controlling these configurations, which frequently leads to the study of decay and boundedness properties of associated operators using tools from Fourier and harmonic analysis.
A central question driving my research is: how large does a set in Euclidean space need to be to guarantee that it determines a rich collection of geometric patterns, such as distances, triangles, or general k-point configurations?
My primary tools are Fourier integral operators and microlocal analysis, which I use to obtain sharp dimensional thresholds for configuration set problems, generalizing the Falconer distance conjecture to a broad class of k-point configurations.
