Narayan Das
Ph.D

I am currently a Post-doctoral Fellow at Georgetown University, working under the supervision of Prof. Nagarjuna Gavvalapalli. I earned my Ph.D. in Chemical Sciences from IISER Kolkata, under the supervision of the Prof. Raja Shunmugam.

My Ph.D. research focused on the design and synthesis of novel copolymers for dual applications in environmental and biomedical contexts. Specifically, I developed polymer-based systems for the detection and removal of hazardous toxicants, as well as for the monitoring of overexpressed enzyme activity in precancerous environments. This interdisciplinary work bridged polymer chemistry, environmental sensing, and biomedical diagnostics, offering innovative approaches to real-world challenges in public health and environmental safety.
