## "India Class" data problems

At the 2020 World Economic Forum in Davos, Santanu talked about his philosophy of solving "India Class" data problems that serve as a template for the rest of the world. According to his talks and writings on the topic, "India Class" problems are defined as being at the crossroad of exploding amount of private data (unstructured, incomplete, incorrect), nascent consumer behaviour with "switchers" who exchange or try out others phones, apps, expectations for software or services being free and relatively limited amount of public data on addresses, population, migration, income etc.

## COVID-19 and data science

The rapid growth of COVID-19 led to an unprecedented response globally. Santanu was appointed as a member of the COVID-19 Mobility Data Network at Harvard University to "provide daily updates to decision-makers at the state and local levels on how well social distancing interventions are working." The team consisted of infectious disease epidemiologists and scientists working in partnership with tech companies to use aggregated mobility data in support of the COVID-19 response.
