Mr. Nikhil Bhatia

Designation: Assistant Professor

Academic Area: Mathematics

Brief Profile:

Mr. Nikhil Bhatia has recently submitted his Ph.D. thesis for evaluation from the Department of Mathematics at the Indian Institute of Technology Ropar, specializing in the analytical and computational study of stochastic thermodynamics and non-equilibrium systems. His research focuses on the mathematical modeling of complex transport phenomena, including exclusion processes, stochastic resetting, and defect-driven dynamics. He has authored multiple peer-reviewed articles in reputed international journals such as Physical Review E, Journal of Statistical Physics, and Chaos, Solitons & Fractals.

With over five years of academic and research experience, Mr. Bhatia has contributed to the teaching of undergraduate and postgraduate courses such as Calculus, Probability & Statistics, and Differential Equations at IIT Ropar and several colleges under the University of Delhi. He has also presented his work at prestigious platforms including the 10th International Congress on Industrial and Applied Mathematics in Tokyo, Japan, and workshops across India and Europe.

Before joining IIT Ropar, he held teaching positions at Dyal Singh College, Hansraj College, and P.G.D.A.V. College, University of Delhi. He also served as a Junior Research Fellow at the Defence Research and Development Organization (DRDO), Delhi, where he worked on cryptology and network security.

Mr. Bhatia holds a Bachelor’s degree in Mathematics from the University of Delhi and a Master’s degree in Mathematics and Computing from IIT Guwahati. His academic journey has been recognized with national-level rankings in CSIR-UGC NET (JRF & LS) and GATE. In addition to his academic pursuits, he has been actively involved in various organizational and welfare activities on campus, contributing to academic, environmental, and social causes.
