Anneclaire De Roos is an environmental epidemiologist with extensive experience studying chemical, physical, and biological exposures as risk factors for chronic and acute health outcomes including cancer, asthma, and infectious illness. Exposure settings of interest include the workplace (pesticides, solvents) and residential communities (pollution, water contamination). Current projects focus on the nexus between the natural environment and human health – such as potential risks and benefits from urban tree canopy. She has served as an expert on several evaluative committees in recent years, including those reviewing pesticides for the International Agency for Research on Cancer (IARC) monograph series, formaldehyde for the NIEHS Report on Carcinogens, and trichloroethylene (TCE) health risk assessments for the EPA and National Academies. At Drexel University, Dr. De Roos teaches classes in Epidemiology and Environmental Health Risk Assessment.
