## Research

**RESEARCH THEMES **Harmonic Analysis

**RESEARCH ACTIVITY**

Jonathan’s interests lie in multivariable Euclidean harmonic analysis and its interactions with problems in geometric analysis and combinatorics. Recently he has been investigating the scope of heat-flow methods and induction-on-scales arguments in the analysis of geometric inequalities arising in the restriction theory for the Fourier transform. Of particular interest to Jonathan are the many ways in which oscillatory phenomena, such as bounds on oscillatory integral operators, are governed by underlying geometric notions such as curvature or transversality.
