My research broadly focuses on how science, technology, and society shape each other. Much of my recent work has focused especially on environmental health governance, predominantly in urban settings. Ongoing projects include a focus on air pollution governance in Indian cities, climate resilience in smart city contexts, and cooling infrastructures in the face of rising temperatures.

I am interested in assessing the impacts climate change may have on environmental/ecosystem health, and subsequently human health. The recent Nature papers explores these in terms of enhanced accumulation of toxincs in marine fishes. Other area of work is the study of elemental biogeochemical cycles, and impact of climate are important.

I am an anthropologist with research interests in media, health and more recently, sustainability. I have supervised a doctoral study on water from an ethnographic perspective. I am also interested in urban governance structures including digitisation. The larger interest is in using a qualitative approach to look at how people understand issues around climate and sustainability.

My research interest lies in the interface of data analysis and optimization. Data analysis includes data based modeling, feature extraction, clustering based unsupervized learning from time independent and time series data of any process related to climate change using AI/ML. Optimization includes optimization under uncertainty, hyper parameter optimization of AI/ML based techniques, supply chain optimization of biofuel based economy including emission effects on climate change, surrogate modeling of computationally expensive models.

My research interest is majorly focussed on sustainable waste management with special emphasis on resource recovery from waste, in short Waste to Energy. I would like to focus on carbon emissions and carbon balance especially from trafic and different biochemical processes that can use emitted carbon as a resource to produce value added products. Briefly, my research is a part of the mitigating or taking precautionary measures to combat climate change.
