Chandra Sekhar Das

Dr. Chandra Sekhar Das is a Research Associate in the Department of Civil and Environmental Engineering at The Hong Kong Polytechnic University. He earned his Ph.D. from PolyU (2025) and B.Tech from IIT (ISM) Dhanbad (2019). His research focuses on developing a deeper understanding of steel corrosion under various microclimates and on developing techniques for the accurate monitoring, prediction, and protection of corroded structures.
