About me

Hello! I am a postdoctoral associate at the Massachusetts Institute of Technology (MIT) with Prof. Marin Soljačić. I earned my PhD in Physics from Penn State in 2023, where I was a part of Prof. Mikael C. Rechtsman’s research group.

I use computational, theoretical, and experimental approaches to study photonic realizations of topological phases of matter, such as Weyl semi-metals and higher-order topological insulators. I am also interested in all things nanophotonics, topological matter, and artifical intelligence (AI) for physics. Read more about my research here.

My CV can be found here.
