My research has a strong interdisciplinary focus and aim to explore how technology, digital intelligence, algorithm, and social science can transform corporates, policy and humanity. My research interest utilizing the above core strength span several topics in Fintech AI, Household finance, Sustainability. I use a data based approach and exploit policy shocks in emerging markets like India, to study the above mentioned topics and its impact on consumer behaviour. The research has implications for business, government agencies  and monetary authorities in India. I work closely with them to use the results of my research towards practical implications.
