Dr. Vaibhav Bisht
Dr. Vaibhav Bisht completed his Ph.D. in Mathematics in 2024 from the Department of Mathematics, Statistics, and Computer Science at G. B. Pant University of Agriculture and Technology, Pantnagar, India. He earned his B.Sc. degree from Kumaun University, Nainital, India, in 2018, and his M.Sc. degree, with major in Mathematics and minor in Computer Science, from G. B. Pant University of Agriculture and Technology, Pantnagar, India, in 2020. Following his doctoral studies, he joined the Department of Mathematics, Jaypee University of Engineering and Technology, Guna as an Assistant Professor (G-I). Dr. Bisht's research is centered on Reliability Theory, Stochastic Processes, and Dynamic Reliability Analysis, focusing on system performance analysis and failure over time. Dr. Bisht has published several research articles in top tier international and national journals.
