I am an Assistant Professor from 02nd January, 2023-Present in the Department of Mathematics, DA-IICT, Gandhinagar, Gujrat India. Earlier, I was a Postdoctoral fellow in Mathematics at Harish-Chandra Research Institute from 16th September, 2022 to 31st December, 2022. Before that, I was a Visiting fellow in Mathematics at TIFR Mumbai from 2nd August, 2022 to 15th September, 2022. My mentor was Prof. Amitava Bhattacharya. Before that, I was a Postdoctoral fellow in Mathematics at IISc, Bangalore from 1st July, 2019 to 30th June, 2022. My mentor was Prof. Arvind Ayyer. I finished my Ph.D in Visva-Bharati University. I defended my Ph.D. thesis in June, 2019.
