I am an Assistant Professor in Statistics at the Indian Institute of Management, Calcutta. Prior to joining IIM Calcutta, I held a Lecturership in Mathematical Data Science at the Queen Mary University of London. Also, I was engaged with the data-centric engineering programme at the Alan Turing Institute. I held a postdoctoral position at the Imperial College London and National Postdoctoral Fellowship in India after completing PhD degree in Statistics from the Indian Statistical Institute. I have several years of industry experience as a Data Scientist in the Analytics sector, providing training and analytical solutions to global clients across industry verticals. I am passionate about solving real-world business problems and issues related to the humanitarian crisis.

Elected Member since 2019, International Statistical Institute. M. N. Murthy Memorial Prize : 2017-2018, awarded by Indian Statistical Institute for outstanding thesis in Applied Statistics. National Postdoctoral Fellowship, 2017, Science and Engineering Research Board, Government of India. Junior Research Fellowship, 2011, Indian Statistical Institute.
As a Data Scientist, my main consulting interest is in the Analytics sector to provide analytical solutions across industry verticals. I work across multiple functions in consulting, including advanced statistical modeling in different analytical domains using both structured and unstructured information with global organizations. I have established and headed an offshore credit risk modeling team and managed onsite projects in the UK and USA for premier banking and financial institutions.

My primary research interests lie broadly in statistical data science and methodology, motivated by real-life challenges arising from complex systems, social science and public policy. In particular, my doctoral work deals with computational and inferential issues in time-dependent stress-strength interference. In postdoctoral research, I worked on modeling and analysis of incomplete longitudinal data with missingness and zero-inflation. Currently, I am working on causal inference and its application in transport networks. I am also engaged in cross-disciplinary work, focusing on data-analytic settings in sports and environmental sciences.
