Dr. Santhoshkumar G is currently serving as an Assistant Professor at the Indian Institute of Technology (IIT) Bhubaneswar. He obtained his Ph.D. and M.Tech. degrees from IIT Kanpur, after completing his Bachelor of Engineering (B.E.) at GCT-Anna University.

With over five years of teaching and research experience, complemented by more than two years of professional experience in field investigations and industrial consultancy, his work bridges academic research and engineering practice. His research focuses on geotechnical engineering, with particular emphasis on numerical modelling, foundation engineering, geotechnical earthquake engineering, and soil–structure interaction. He has published over 20 papers in reputed peer-reviewed journals and has presented his research at several national and international conferences.

His research interests encompass numerical and analytical methods in geomechanics, with a focus on topics such as retaining systems, rigid pavements, skirted footings, interaction effects, and the effects of earthquakes on geotechnical structures. Additionally, he has conducted extensive analyses of pile foundations and ground improvement methods.
