Haider A. Khwaja is an assistant 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 water and air quality and their impact on human health, acid rain, and transport of atmospheric pollutants including inorganic and organic species.

Some of the studies conducted are:

  • Acid Rain: Identification of pollution sources in atmospheric precipitation for episodic high concentration of inorganic and organic pollutants, and trace metals using multivariate analysis;
  • Cloud Water Chemistry: Studied cloud water chemistry for understanding the incorporation of ambient aerosols, dissolution of trace gases, and their subsequent transformation into acidic species;
  • Investigation of Atmospheric Carboxylic Acids and Their Precursors: Undertook a comprehensive study of carboxylic acids in urban and rural environments to understand the source-sink relationship, which in turn are important to validate current tropospheric model predictions on chemical processes, acid deposition, and global warming;
  • Chemical Characteristics of Fine Particles Responsible for the Observed Health Effects: Knowledge of the organic carbon composition of PM2.5 is the need of the hour to judge the possible implications for human health, visibility degradation, and cloud nucleation properties. A research project is in progress aimed at comprehensive understanding of the identity, concentrations, and sources of individual organic chemical species that are associated with the carbonaceous PM2.5 in New York State;
  • Water and Human Health Issues, such as Drinking-Water Quality and Human Health Risks Associated with Water Contaminants; and
  • Exposure and Health Impacts Related to Indoor and Outdoor Air Pollution Including Studies of Indoor Allergens, Diesel Vehicle Emissions, Volatile Organic Compounds, PAHs (Polycyclic Aromatic Hydrocarbons), and other Air Toxins.
