Arkajit is an Assistant Professor in the Department of Chemistry at Texas A&M University. His research focuses on understanding quantum dynamical phenomena in various chemical systems and materials.

Arkajit completed his Ph.D. under the supervision of Prof. Pengfei Huo at the University of Rochester, where he worked on simulating the quantum dynamics of molecules interacting with radiation. During his doctoral studies, he developed nonadiabatic quantum dynamics scheme and explored new chemical reactivities in molecules coupled to quantized radiation inside an optical cavity (so called polariton chemistry) and contributed to the development of various theoretical frameworks for molecular quantum electrodynamics.

In 2021, Arkajit joined Columbia University as a postdoctoral research scientist, where he worked with Prof. David R. Reichman. His research at Columbia involved investigating the transport properties of excitons and decoherence in materials coupled to confined photon modes.

Arkajit joined Texas A&M as an Assistant Professor in 2024.
