Biography:
Haider A. Khwaja is an associate professor of environmental health sciences and a research scientist at the New York State Department of Health's Wadsworth Center. His research and teaching interests lie in the field of Environmental Health. Active research programs include the study of multidisciplinary environmental chemistry related to air and water quality and their impact on human health, sources and fate of chemical contaminants; cloud water chemistry; and acid rain.

Some of the studies he's conducted include:

Particulate matter, air quality and human health: Acquiring the knowledge for maintaining and improving air quality is one of the major environmental problem of concern as it has been estimated by WHO that air pollution contributes to more than 7 million deaths a year worldwide. To address these issues, we investigate a wide range of scales from the assessment of reactive oxygen species (ROS) activity of fine particulate matter (PM2.5), to observations in outdoor and indoor environments, to studies of the effects of short-term exposure of PM2.5 on daily morbidity and mortality due to cardiovascular and pulmonary diseases among adults and young children residing in various communities of large cities.

• Acid Rain: Careful monitoring of precipitation chemistry is essential to fully understand the threat of anthropogenic pollution to such susceptible areas as NYS. This project focuses on identification of pollution sources in atmospheric precipitation for episodic high concentration of inorganic and organic pollutants, and trace metals using multivariate analysis.

Tracking environmental contaminants and microorganisms in New York State (NYS) schools: In collaboration with Dr. Shao Lin (University at Albany) and Dr. Kerry Kinney (University of Texas, Austin), environmental pollutants (PM, CO2, CO, formaldehyde, and volatile organic compounds (VOC)) are being monitored in classrooms at 10 randomly selected NYS schools. The aim of this project is to examine the relationship between school’s environment and occupant health, learning, and performance in NYS schools, and to promote the best school practice.

Sources & fate of chemical contaminants: We study sources, transport, and sink of environmental pollutants including inorganic and organic species. This is carried out by state-of-the-art techniques for chemical analysis, laboratory experimentation, and field sampling.

Water and human health issues: To evaluate drinking water quality and human health risks associated with water contaminants, we conduct monitoring studies and develop new methods for chemical analysis (e.g., hexavalent chromium, perchlorate).
