Mountain Climate Modeller
Biography
I am a ‘Mountain Climate Modeller’ in the the Atmosphere, Ice and Climate team. I am also a Senior Member of St. Edmund’s College, Cambridge. I am currently working with Dr Andrew Orr and Dr Hamish Pritchard on an ambitious UKRI/NERC-funded Highlight project called ‘The Big Thaw: https://www.bas.ac.uk/project/the-big-thaw/). Over the past two years, my work has focused on understanding snowfall in the Himalayas and the Alps – crucial sources of freshwater for rivers that sustain large populations and ecosystems. I am currently undertaking high-resolution atmospheric modelling work using the MetUM regional climate model with the state-of-the-art CASIM microphysics to address the question: How much snow accumulates in mountain catchments, and how will it change?
I also have field experience as Mission Scientist with the Facility for Airborne Atmospheric Measurements (FAAM) research aircraft, flying air-borne sorties over the European Alps as part of the international TEAMx observational campaign.
Before moving to BAS, I earned undergraduate and doctoral degrees in Chemical and Mechanical Engineering (Cloud Physics) in India. My PhD led to conceptual advances on the transformation of vehicle-mediated particles into cloud droplets. This research was a collaboration with the Indian Institute of Tropical Meteorology, Pune (Ministry of Earth Sciences, Government of India), as part of the Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX) field campaign (URL: https://www.tropmet.res.in/~caipeex/).
Additionally, my work has garnered attention in the British and Indian media, including an article in New Scientist (https://www.newscientist.com/article/2281560-a-1000-year-old-indian-temple-had-an-early-form-of-air-conditioning/).
