I am a PhD candidate in Mathematics at the University of Idaho, Moscow, ID, USA. I work in Applied Harmonic Analysis, exploring how mathematical tools such as Fourier series, Slepian series, frames, and wavelets can be used to represent, decompose, and reconstruct signals. A central theme in my work is the Gibbs Phenomenon — the behavior of function approximations near discontinuities — and how different methods can be used to mitigate it. My research bridges classical harmonic analysis with modern signal processing techniques.
