Ph.D. Candidate at School of the Environment, Nanjing University


Riyang is a visiting doctoral student in the Environmental Health Sciences Department at the Yale School of Public Health. His research focuses on exposure assessment of air pollutants and non-optimum temperature with multidisciplinary approaches. His dissertation aims to capture the uncertainty level of the estimates of statistical models, and improve the interpretability of models to expand their application. At Yale, Riyang hopes to learn environmental epidemiologic methods and climate change models and conduct his research on Predicting daily air temperature over the United States from open-access data using a statistical model.
