Riya Ghosh
Currently, I am a Postdoctoral Researcher in the Department of Mathematics at the Indian Institute of Technology Bombay, working with Dr. Chandan Biswas since July 2025. I was a visiting researcher at Imperial College London (South Kensington, UK), hosted by Dr. Ayush Bhandari.
Previously, I served as an Assistant Professor in the Institute of Technical Education and Research (ITER), Siksha ‘O’ Anusandhan, Bhubaneswar, Odisha, India, from 29th October 2024 to 8th July 2025. I completed my Ph.D. under the supervision of Dr. A. Antony Selvan in the Department of Mathematics & Computing at the Indian Institute of Technology (ISM) Dhanbad in 2024.
My research interests focus on computational and numerical harmonic analysis, emphasizing mathematical sampling theory, Fourier analysis, and time-frequency analysis.
