My present research focuses largely on non-Hermitian physics and open quantum systems, developing analytical approaches to interesting questions in quantum physics. I also pursue the mathematical foundations of non-Hermitian and quasi-Hermitian quantum theory, and have a strong background in mathematical physics and quantum gravity.

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.
