Sujeet Kumar Singh

I work in the theoretical and computational aspect of modular forms and its generalizations. Currently, I am a postdoctoral fellow in the School of Mathematical Sciences, University of Nottingham, working with Dr. Fredrik Stromberg. I completed my Ph. D. from NISER Bhubaneswar under the supervision of Dr. Jaban Meher.
