My research focuses on harmonic analysis in nondoubling contexts, particularly investigating operators such as the Riesz transform, Hardy-Littlewood maximal operators, and spectral multipliers of Laplacians. I am also interested in Hardy spaces and heat kernel estimates. Central to my research is exploring whether well-established results in classical scenarios maintain their validity within nondoubling contexts and analyzing any discrepancies that may arise.
