Assistant Professor
Ph.D. University of Durham, Durham, UK.
"I
pursue research in the broader area of (a) environment and health, (b) methods
of geo-spatial analysis, (c) location-allocation for decision support system,
and (d) spatial-statistical methods of visualization. In the first, I study
the health outcomes of human interaction in social and physical environments."
My current NIH project examines the association between
long term personal exposure and respiratory health in pre (before the year
2002) and post air pollution regulation periods in Delhi, India. The research
exploits advances in atmospheric remote sensing and geo-spatial analysis
for estimating air pollution at a high spatial resolution (such as at every
household location) in pre and post regulation periods, and for imputing
long term personal exposure to air pollution. An individual’s personal
exposure is retrieved by linking his/her (routine) spatial interaction with
the air pollution level at every place this individual has spent sometime
during the course of his/her life.
In the second, I work on the methods of examining spatial dependency and causality of stochastically distributed point events; these methods have edge over the conventional methods that are based on the characteristics of the Cartesian space. In the third, I use location-allocation models for service area demarcation, locational efficiency evaluation of services and planning public and private services. In the final, my research focus is on innovative methods of visualization that improve our understanding of the underlying spatial-statistical structure of the mapped data.

Selected Grants:
- 2005-2007: Health and Air Quality Regulation in Delhi, India: The main goal of this project is to estimate air pollution at a high spatial-temporal resolution in pre and post environmental regulation periods in Delhi using atmospheric remote sensing and geo-spatial methods, and then use these estimates to compute long term personal exposure to ambient air pollutants and its effect on respiratory health. Air pollution and health data will be collected in Delhi, which has been subject to environmental regulation in recent years, and its neighboring districts, largely unaffected by such regulation. The air pollution estimates to be retrieved from MODIS satellites in the post regulation period will be validated using the air quality data to be collected at 150 sites in Delhi and 50 sites in the neighboring states. The project also includes the second round of survey of the 1600 households (in the year 2006-07) that were surveyed in January-March 2004. (Role: Principal Investigator; Collaborators: Prof. Andrew Foster, Economics Dept, Brown University, Dr. Allen Chu, NASA, Dr. Sachidanand Tripathi, Indian Institute of Technology, Kanpur; Funding Agency: NICHD, NIH; Amount: $275,000.)
- 2003-2005 Urbanization, Health, and Environmental Quality in coastal Ghana: In this project, we are investigating the effect of urbanization on environmental and health risks, and how these in turn influence local thinking about environmental issues. The main goals of the project are to (1) examine association between population dynamics and pollution levels in eight lagoon, (2) conduct focus groups and in-depth interviews with respondents located in the region, addressing questions of health behavior and demographic activity, (3) conduct exploratory drinking water quality measurements at the household and community level, (4) delineate watersheds of coastal water bodies, (5) develop a population growth and land use profile of the study area, and (6) conduct preliminary analysis of the interrelationships among urbanization, lagoon water quality, fish catches and human health. (Role: Co-Investigator; PI: Prof. Michael White, Brown University; Funding Agency: NIH; Amount: $200,000)
- 2003-2004: Air Quality and respiratory health in Delhi, India: The main objectives of this project were (a) to evaluate the feasibility of retrieving indirect estimates of air quality from satellite imageries based on the relationship between aerosol optical depth retrieved from satellite imageries and air pollution measured at 113 sites in Delhi, India and (b) to examine the association between the state of respiratory health and exposure to air pollution, measured by suspended particulate matters (PM2.5). We collected data on suspended particulate matters in a range of 1 to 10 micron (aerodynamic diameter) at 113 sites in Delhi (India) from July-December 2003, followed by an extensive respiratory health, socio-economic and demographic survey of 1,600 households (about 4000 individuals) in different strata identified based on air pollution levels and proximity to pollution sources from January to March 2004. (Role: PI; Co-PI: Prof. Andrew D. Foster, Brown University; Funding Agency: Seed Grant, Population Studies and Training Center (PSTC), Brown University; Amount: $50,000).
- 2003: Air Quality and Respiratory Health in Delhi – Feasibility Analysis: The main objective of the award was to examine the feasibility to study the health effects of recently implemented air quality regulation in Delhi, India. (Role: PI; Funding Agency: Seed Grant, PSTC, Brown University; Amount: $3,500)
