About Me: I earned my Ph.D. in Applied Mathematics from IIT(ISM) Dhanbad in March 2012. Shortly after, in June 2012, I joined the Department of Mathematics & Computing at IIT(ISM) Dhanbad as an Assistant Professor. Currently, I hold the position of Associate Professor in the same department. Before joining IIT(ISM) Dhanbad, I worked as a Lecturer at Pt. Ravishankar Shukla University, Raipur, and NIT Raipur. I completed my Bachelor's degree in Science and Master's in Mathematics from Govt. College of Science, Guru Ghasidas University, Bilaspur, in 2003 and 2005, respectively. My current research interests focus on mechanics of solids with emphasis to wave dynamics in smart composite structures, and the analysis of ionospheric perturbations using AI.

Research Interest: Electro-elastodynamics & Magneto-elastodynamics, Solid Mechanics (Wave transference in various smart materials), Early Earthquake Warning System (Ionospheric Perturbation Analysis).
