Overview


My research is in the area of probability and partial differential equations, which have been used to model many phenomena in the natural sciences and engineering.  Asymptotic analysis has been a common theme in much of my research.  Current research interests include: stochastic dynamics, interacting particle systems, reaction-diffusion equations, applications to biological models.

On spectral interference of the short-time Fourier transform and its nonlinear variations

Journal Article Applied and Computational Harmonic Analysis · July 1, 2026 Spectral interference, commonly referred to as the beating phenomenon, can severely distort time-frequency representations (TFRs) in physical applications. We study this phenomenon for the short-time Fourier transform (STFT) with a Gaussian window and for ... Full text Cite
