Arnab Kumar Ray

PhD (Physics), Jadavpur University, Kolkata


I hold a doctorate in astrophysical fluid dynamics. My research methods are theoretical in nature, with my present research interests being astrophysical accretion, fluid dynamics and nonlinear systems. I have publications in
peer-reviewed journals of astrophysics, gravitation, nonlinear dynamics, condensed matter physics, nuclear physics, complex systems and geophysics.

I also have research experience in the seismic processing industry. I have interest in designing curriculum and exploring new pedagogic approaches to aid the teaching-learning process.
