Biography

I am working on an ambitious new UKRI/NERC-funded Highlight project called ‘The Big Thaw: https://www.bas.ac.uk/project/the-big-thaw/) with an aim to assess past, present and future changes in global mountain water resources by investigating ice/snow accumulation in high mountain regions. Working within the ‘atmospheric modelling’ work package of this project, I am currently undertaking high-resolution atmospheric modelling work using the MetUM regional climate model (RCM) with the current state-of-the-art CASIM microphysics to address the question: How much snow accumulates in selected key mountain catchments, and how will it change?

My PhD led to conceptual advances on the re-distribution and transformation of vehicle-mediated particles released in complex mixtures of aerosols into cloud droplets entailing solution non-ideal effects. 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 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).

My work has also received attention in the British media, including an article in New Scientist, a UK-based science magazine under the Daily Mail Trust and the Royal Meteorological Society of Great Britain (https://www.newscientist.com/article/2281560-a-1000-year-old-indian-temple-had-an-early-form-of-air-conditioning/). Additionally, I hold a position as a Research Associate at St. Edmund’s College, University of Cambridge.
