Research Interests

My research interests lie at the intersection of harmonic analysis, number theory, spectral theory, and partial differential equations. I am particularly drawn to exploring the interplay between these fields, focusing on how analytical methods can shed light on deep structures within mathematics. My work aims to address fundamental questions while uncovering connections between theoretical concepts and their applications.
