On completion of his deputation, he returned to IIT BBS but stayed there only for three more years and joined the Indian Institute of Technology Delhi (IITD) in 1998 as a professor at the Centre for Atmospheric Sciences.

[11] He is also a former visiting scientist at the Asian Disaster Preparedness Centre, Thailand[12] and is a faculty member at the University Network for Climate and Ecosystems Change Adaptation Research (UN-CECAR) of the United Nations.

[15] He overseas a team of researchers engaged in the study of coastal inundation with a view to develop Land-Ocean-Atmospheric Modelling System for predicting extreme weather events.

[20] He has edited the book, Advanced Numerical Modelling and Data Assimilation Techniques for Tropical Cyclone Prediction, published by Springer Science+Business Media in 2016.

[25] He is known to have made over 45 international visits[11] and has delivered plenary or invited addresses at several conferences and seminars including the lecture on Numerical Simulation of Track and Intensity of Orissa Super Cyclone-1999 at the 5th International Conference on Information Technology in 2002,[26] the seminar on Numerical Modeling of Land Surface Processes for Improved-Simulation of Extreme Weather Events over the Indian Region of 2014[27] and the Colloquium on Recent Developments in Prediction of Tropical Cyclone and Associated Coastal Hazards of 2016,[28] both held at IIT Bhubaneswar, and the National Workshop on GPS RO Techniques and Applications of 2015 held at SRM Institute of Science and Technology.
