Areas of Interest, My work is focused

• Monsoons and its variability at various scales using models of climate.


• AI/ML for climate and weather studies.


• exploitation of High Performance Computing innovatively for climate studies.

External Interaction

• Director, Monsoon Mission - A mission mode project to improve forecast of monsoons at all scales and use of predictions in various sectors . This involved interacting various institutions within the country and outside


• I was involved in a project sponsored by Intel Inc. titled Intel Parallel Computing Centre for Modelling Monsoons and Tropical Climate (IPCC-MMTC) for using computational accelerators such as Xeon-Phi for climate modelling. This research was conducted in collaboration with National Centre for Atmospheric Research (NCAR) of USA.


• Earlier I have been involved in projects sponsored by Microsoft and IBM on useof HPC for climate studies.


• I have also worked with India Meteorological Dept on using numerical models for forecasting monsoons.
