Bio
I am a doctoral student, and my scientific career has been involved with understanding microscale processes in atmospheric flows. These flows are non-linear, and exhibit compelling visuals governed by complex multi-scale dynamics (for instance, fluffy, cauliflower-shaped cumulus clouds). In particular, I have worked on assessing aerosol cloud interactions over polluted mega-cities where informal cooking methods from crowded shackles and shantytown settlements dispense copious amounts of carbonaceous particles into the city’s urban boundary layer. Have worked on resolving chemico-thermodynamical effects operating upon vehicle-generated emissions where the assumption of hydrophilicity breaks down. My work has established that moist thermodynamics is mediated by alterations in material accretion on sub-micron carbonaceous particles. Have also explored more accurate diffusional uptake pathways of trace gas diffusion into cloud hydro meteors. As an important outcome, the results from my work provide crucial information to city planners and regulators dealing with the relocation of inhabitants of low-lying shantytowns prone to flooding through early-warning systems. Finally, my research has led to conceptual advances on the re-distribution and transformation of vehicle-mediated particles released in complex mixtures of aerosols entailing solution non-ideal effects.
Apart from my independent research, I have worked on undergraduate team projects (fructifying into international peer-reviewed publications) with my colleagues: Projects include 'Developing a synergy between Meteorology and the Built Environment'. Specific projects include exploring bio-climatic responses in an ancient settlement constructed in South India (https://link.springer.com/article/10.1007/s00484-021-02153-6).
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 (https://www.newscientist.com/article/2281560-a-1000-year-old-indian-temple-had-an-early-form-of-air-conditioning/) and the Royal Meteorological Society of Great Britain.
Parallel pursuits:
Apart from research, I am an amateur scribbler and a painter interested in art forms of all types. I also like my tea with a tasteful book. I am enjoying 'The Tomb of Sand' by Geetanjali Shree at the moment.
