I study how surface ozone and its precursors behave across Indian cities — from decade-long CAAQMS records to the machine-learning models that forecast them — and manage the national monitoring infrastructure that makes that data possible.
I am a Senior Executive (Environmentalist) at ENVEA India Pvt. Ltd. (Central Pollution Control Board CAAQMS Project), where I manage the operation and maintenance of CPCB's Continuous Ambient Air Quality Monitoring Stations (CAAQMS) across Delhi, Lucknow, Chennai and Bengaluru — part of the backbone of India's national air quality data infrastructure.
Alongside this, I am a sixth-year PhD scholar at CSIR-National Physical Laboratory, working under the supervision of Dr. Radhakrishnan S.R. My doctoral thesis — "Studies on the Variation of Ambient Ozone and its Precursors in Different Indian Environmental Conditions" — has been submitted and is currently under evaluation.
My work sits at the intersection of long-term monitoring, atmospheric chemistry, and applied machine learning — using over a decade of hourly CAAQMS observations to understand why ozone behaves differently from one city, one season, and even one year to the next.
