3) Gaurav Das

Started out on July-2015 as a Masters student. Batch topper. Written five papers as a Masters student. 3 of them got accepted: 1 in ASCE, 1 in ASTM and 1 in Catena. His 4th paper in Catena received favourable reviews and the 5th one is under review in ASCE, International journal of Geomechanics.

4) Manu Krishnan

Started out on July-2015 as a Masters student. Joined the doctoral program at Virginia Tech in Aerospace Engineering. Batch topper in Masters (CPI 9.85). Published 3 papers with Basuraj Bhowmik. Technically very strong, he is certainly the most sharp-witted student I have come across in recent times.
