Q&A Session

Dr. Siddharth Pathak is a Technical Support Engineer at the MIDAS R&D Centre, Navi Mumbai, specializing in geotechnical numerical modelling with MIDAS GTS NX. He holds a Ph.D. in Geotechnical Engineering from IIT Mandi, where his research focused on strain-rate effects in sand and pile behavior under rapid load tests. Before joining MIDAS, he gained valuable industry and consultancy experience in geotechnical design, including slope stability, deep foundations, and ground improvement.
