Postdoctoral Researcher, Hunan Normal University

About me

I hold a PhD in Physics from the School of Physics at the University of Hyderabad, where my research centered on quantum gravity utilising non-commutative space-time. I am dedicated to investigating the fundamental nature of space-time and its significance for our comprehension of the universe.

I am currently pursuing a postdoc at the Hunan Normal Univerisity and am eager to leverage my expertise to make contributions to advancing the frontiers of scientific knowledge.
