Biography

I am a PhD student at the Wolfson Atmospheric Chemistry Laboratories studying atmospheric chemistry in Delhi, India. My interest in air quality research was sparked by a summer placement in WACL after the second year of my undergraduate study. Since then, I have worked with chemiluminescence and gas chromatography instrumentation. My masters project involved quantifying emission fluxes from West Africa using the mass balance approach and the development of a new photolytic cell for the chemiluminescence detection of NOx in remote locations. 

Qualifications

MChem Masters in Chemistry (University of York, 2017)

Research interests

My main interests include the effects of air pollution and air quality in megacities. A recent study by the WHO identified Delhi as one of the most polluted cities in the world with an estimated 20,000 air pollution related deaths annually. My work focuses on exploring the unique and complicated chemistry underpinning poor air quality in Delhi.

Project title

Atmospheric Chemistry in an Indian Megacity

Supervisors

Funding

Leeds York NERC SPHERES Doctoral Training Partnership (DTP)

Project outline

A unique and comprehensive observational dataset of primary and secondary pollutants and reactive intermediates will be obtained at two sites in the Delhi metropolitan area. The measurement suite will then be used to constrain photochemical models, incorporating the highly detailed Master Chemical Mechanism (MCM). The project will focus on understanding OH reactivity, determining radical sources and evaluating reduced chemical schemes against the benchmark MCM in order to determine the relative importance of OH sources in Delhi. This allows for the factors that drive in-situ ozone production to be investigated.
