Dr. Changjie Cai is the founding Director of the Children’s Environmental Health Center in U.S. Southern Great Plains, which is a core Center in the Hudson College of Public Health at the OUHSC. He is the PI of a biosafety level 2 lab (BSL2), which is a core research lab in the College. His background is Meteorology and Occupational and Environmental Health. Research in Dr. Cai’s lab focuses on three directions: (1) identifying and assessing exposure to hazards (e.g., aerosols, bioaerosols, gases, etc.) and their controls; (2) integrating advanced techniques (e.g., machine-learning, advanced materials) into Occupational and Environmental Health fields; (3) studying air pollutants and their climate effects using atmospheric dynamic models (e.g., WRF-Chem); and (4) environmental equity and sustainability.
