Biography

Atmospheric modelling has again come center stage in Global Forums, including the recently concluded COP28 and G20 Summit. Amongst other things, the Summits have discussed new Policies for Sustainable Development in Developing Economies. The tenuous exercise of undoing the disequilibrium unleashed from unregulated development has to be tackled comprehensively. Standalone engineering fixes will fail unless new research and innovations are fully interpreted, understood, and then disseminated to policymakers for further action. The problem of interpretation thus combines an incredible amount of ingenuity and mathematical acumen to distinguish between the genuine and the spurious.

I am presently working on the ‘The Big Thaw: gauging the past, present, and future of our mountain water resources’ project (https://www.bas.ac.uk/project/the-big-thaw/), which is an ambitious new UKRI/NERC-funded project assessing past, present and future changes in global mountain water resources from snow and ice. Working within the ‘atmospheric modelling’ work package of The Big Thaw project, I am currently undertaking high-resolution atmospheric modelling work using the MetUM regional climate model (RCM) to address the question: How much snow accumulates in selected key mountain catchments, and how will it change? The crucial task involves optimizing the current state-of-the-art Met Office’s Unified Model to get snowfall right over High Mountain regions, including the Alps and the Himalayas.

During my Bachelor’s in Chemical Engineering, I have been trained to acquire the thorough knowledge expected from a rigorous engineering degree. Thereafter, I was offered admission to the Chemical Process Engineering programme of Imperial College, London; however, on its heel also came an offer of a fully funded Integrated PhD, at the School of Mechanical Engineering, Vellore Institute of Technology (ranked 12th best among engineering colleges in India) which I decided to accept. This involved a project that dealt with the chemical conversion of soot and black carbon particles into cloud condensation nuclei. This involved a collaboration with the Indian Institute of Tropical Meteorology, Pune (Ministry of Earth Sciences, Government of India) under the aegis of the Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX) (URL: https://www.tropmet.res.in/~caipeex/). Some of this (a large part of my PhD research) was featured in IITM’s cloud physics lecture series following the International Conference on Cloud Physics and Precipitation, 2021 (URL: https://www.youtube.com/watch?v=TNpMZPyCJSc)

I have also presented my work (collaborative research with British Antarctic Survey, UK) at Cambridge University, UK and the recently concluded International Conference on Clouds and Precipitation (collaborative research with IITM, Pune, Ministry of Earth Sci., Govt. of India) as a plenary session speaker.

My research has also been covered by the British print media including New Scientist – a UK based Science Magazine under the aegis of the Daily Mail Trust and the Royal Met. Soc. of Great Britain.

I am also an elected Post-Doctoral Research Associate at St. Edmund’s College, University of Cambridge.
