Dr. Ajit Singh is Research Associate at the Department of Mathematics, Indian Institute of Technology Guwahati, Assam. He obtained his B.Sc. in 2015 from Ewing Christian College, an autonomous constituent college of Allahabad University, Prayagraj and his M.Sc. in 2017 from the Indian Institute of Technology Guwahati. He then earned his Ph.D. in June 2022 from the Indian Institute of Technology Guwahati, Assam under the supervision of Prof. Rupam Barman. Dr. Singh is primarily interested in number theory: in particular, partition theory, mock theta functions, modular forms, and harmonic maass forms. His research is deeply influenced by the work of Ramanujan. Dr. Singh has published several research articles in reputable international journals. He has also qualified IIT-JAM, CSIR-UGC NET, and GATE examinations.

As a Fulbright-Nehru Postdoctoral Research fellow, Dr. Singh has joined the Department of Mathematics, University of Virginia, Charlottesville, VA. He is working on arithmetic properties of certain partition and mock theta functions using the q-series manipulations, modular forms, and harmonic maass forms theory. He is primarily focusing on Wang’s and Mahlburg’s conjectures on the mock theta functions and overpartitions, respectively.

Dr. Indranil Chakraborty is currently an institute postdoctoral fellow at the Department of Physics, Indian Institute of Technology Bombay, where he has been working since May 2023. He earned his bachelor’s degree in physics from St. Xavier’s College (Autonomous), Kolkata, affiliated with University of Calcutta, in 2015. He then completed both his master’s degree in physics (2017) and PhD (2023) at the Indian Institute of Technology Kharagpur, West Bengal.

Dr. Chakraborty’s research interests lie in gravitational physics, particularly in the study of gravitational wave memory effects — a subtle and yet-to-be-detected phenomenon predicted by general relativity. Over the years, he has authored several research articles, including a single-author publication in reputed international journals.

As a Fulbright-Nehru Postdoctoral Research Fellow at the University of Virginia, Charlottesville, VA, Dr. Chakraborty is investigating how gravitational wave memory effects manifest in cosmological settings. His project also aims to develop a formalism for calculating memory effects in modified theories of gravity. This research is crucial for next-generation gravitational wave detectors, as they are expected to probe potential deviations from general relativity — currently the best-verified theory of gravity.
