Current Research Interest:

• Environmental interventions and health: The key objective of this research is to address some of the methodological challenges to measure air quality in pre and post environmental regulation periods, particularly in Delhi, and determine indoor, outdoor and travel related air pollution exposure in terms of people’s interaction in space. We are examining the feasibility of remote sensing technology to retrieve indirect estimates of air quality due to limited availability of air pollution data in terms of temporal and spatial coverage. For this purpose we have already established 113 air pollution monitoring sites in Delhi, where we record data on suspended particles in the range of 1 to 10 micron in addition to relative humidity and temperature at every site. These estimates will provide sound basis for relating aerosol optical thickness (AOT) estimates to be retrieved from MODIS and IRS satellites at 250m and 23.5m respectively. In Dec. 2003 and Jan 2004, we plan to administer a survey of about 3000 households in Delhi to examine the status of respiratory health of the individuals living in different strata to be identified on the basis of air pollution levels and proximity to pollutant sources.
