My present research focuses largely on non-Hermitian physics and open quantum systems, with applications towards open light-matter systems and sometimes general platforms. I have a strong background in mathematical physics and quantum gravity, and currently develop analytical frameworks that combine methods from theoretical and mathematical physics with quantum and statistical mechanics to understand, model, and predict testable phenomena.

I have a strong interest in pedagogy.

Currently, I am working at the Rochester Institute of Technology as a postdoctoral associate. I received my PhD in 2025 from the Indian Institute of Technology (IIT) Bhubaneswar in India where my research was funded by the Prime Minister's Research Fellowship.
