I am currently an Instructor in Physics at the Talent Development Centre, IISc Challakere Campus.

Before joining IISc, I worked as a Goverment Guest Lecturer in the Department of Physics at MAMO College Manassery, affiliated to the University of Calicut.

I was also a Postdoctoral Fellow at the Raman Research Institute, where I worked with Dibyendu Roy in the Theoretical Physics Department. My research focused on nonequilibrium statistical physics, with particular emphasis on heat transport in low-dimensional systems.

I completed my PhD in Physics from the Chennai Mathematical Institute (CMI), under the supervision of Govind S. Krishnaswami. My doctoral research centered on classical and quantum integrable systems, field theories, and related areas of theoretical and mathematical physics.

My primary research interests include integrable systems, nonequilibrium statistical physics, and open quantum systems. More broadly, I enjoy exploring interesting problems across theoretical and mathematical physics.

Here is my brief Curriculum Vitae.
