Dr Achintya Roy
- Assistant Professor
- Area: Mathematics and Basic Sciences
Dr Achintya Roy is an Assistant Professor in the area of Mathematics and Basic Sciences at NIIT University (NU). Dr. Roy has earned his PhD in Statistics from the Indian Institute of Technology Kharagpur. He has completed his BSc (Mathematics Honors) from Barasat Government College and MSc (Mathematics) from the Indian Institute of Technology Kharagpur. He works in the area of Applied Probability, specifically in Reliability Theory. He is primarily interested in the study of standby redundancy. Standby redundancy is a commonly used technique to increase the reliability of a system. He has studied the reliability properties of a k-out-of-n system, equipped with two cold standby components as well as the reliability of a coherent system equipped with two cold standby components. His research areas include – Stochastic Aging and ordering, Reliability estimation, Entropy and Extropy.
