    Research Overview

  • Dr. Vilcassim's primary area of interest for research is the health effects associated with or caused by exposure to environmental pollutants, with a special focus on particulate matter air pollution in urban environments.

    Specific research interests include, Low-cost sensor methods to measure exposures and cardiopulmonary health, and study dose-response relationships; Sources and composition of urban air pollution and their impacts on residents; Air quality in underground subway systems; Adverse health impacts of traveling to/visiting polluted cities abroad (Eg. Travelers from the US to New Delhi, India; Beijing, China); and Health and air quality impacts of using alternative tobacco products.
