# Sudipto Banerjee

Sudipto Banerjee (born October 23, 1972) is an Indian-American statistician best known for his work on Bayesian hierarchical modeling and inference for spatial data analysis. He is Professor of Biostatistics and Senior Associate Dean in the School of Public Health at the University of California, Los Angeles. He served as the Chair of the Department of Biostatistics at UCLA from 2014 through 2023. He served as the elected President of the International Society for Bayesian Analysis in 2022.

## Early life and education

Banerjee was born in Kolkata, India. He attended Presidency College, Kolkata for his undergraduate studies, and the Indian Statistical Institute, graduating with an M.STAT in 1996. Subsequently, he moved to the United States and obtained an MS and PhD in statistics from the University of Connecticut in 2000, where he was introduced to Bayesian statistics and hierarchical modeling by Alan Enoch Gelfand who had been a pioneer in the development of the Gibbs sampler and Markov chain Monte Carlo algorithms in Bayesian statistics.

## Career

Banerjee joined the University of Minnesota, Twin Cities in 2000 as an assistant professor of Biostatistics and was associated with the School of Public Health for 14 years. There he worked on a number of problems and wrote numerous articles on spatial statistics, developing theory and methods related to Bayesian modeling and inference for geographic data with wide-ranging applications in public and environmental health sciences, ecology, forestry, real estate economics and agronomy. In 2014, Banerjee joined the Department of Biostatistics in the School of Public Health at UCLA as Professor and Chair of Biostatistics.

## Research

Banerjee is widely recognized as a leading expert in spatial statistics and its diverse applications in environmental, social and health sciences. He has made fundamental and pioneering statistical contributions in the broad area of Bayesian statistics and hierarchical models for analyzing spatial-temporal data and, more specifically, in the following areas within space-time modeling: (i) statistical inference for spatial gradients and zones of rapid change (also called wombling); (ii) scaling up Gaussian process models for massive spatial data analysis; (iii) graphical models for high-dimensional spatial data analysis; (iii) spatial frailties and space-time survival analysis; and (iv) computational algorithms and software for spatial data analysis. His notable statistical innovations include Gaussian predictive process and Nearest-Neighbor Gaussian process models for massive spatial-temporal data, and multivariate Markov random fields for regionally aggregated spatial data.
Banerjee's interdisciplinary research contributions include his leadership in statistical science and oversee activities surrounding exposure data science in the GuLF Study (Gulf Long-term Follow-up Study) Program examining the human-health consequences of the Deepwater Horizon oil spill in April 2010. The spill followed an explosion on a drilling rig leased by BP, the British oil company, and led to the release of over four million barrels of oil into the Gulf of Mexico, 48 miles off the coast of Louisiana in the United States. Banerjee has been actively involved in collaborative frameworks involving public health researchers with expertise in epidemiology, environmental and occupational health, and biostatistics that would be responsible for sound statistical practices including innovative methods for comprehensively analyzing the exposure of workers to potentially harmful chemicals. In another high-profile study, Banerjee was invited to serve on a committee formed by the National Research Council and the National Academy of Sciences in 2015-16 for his expertise in the use of spatial data science in analyzing and synthesizing geographically referenced flood insurance data in devising an affordability framework for Federal Emergency Management Agency (FEMA). Professor Banerjee contributed with his expertise in spatial data science and GIS technologies within a comprehensive policy framework to ascertain when and where premium increases from the Biggert–Waters Flood Insurance Reform Act of 2012 lose cost effectiveness.
