Christian Sewor, Student and New Researche Network (SNRN) Liaison
Christian Sewor is a doctoral candidate in the Environmental Health (Epidemiology specialization) program at Colorado State University’s Department of Environmental and Radiological Health Sciences. His research focuses on the cardiometabolic and inflammatory impacts of household air pollution in low-resource settings, using both longitudinal and cross-sectional data from randomized cookstove intervention trials in Honduras and Rwanda. Christian’s work places a particular emphasis on identifying effect modifiers to better understand population-level differences in exposure-outcome relationships. By exploring these sources of heterogeneity, his research aims to inform more targeted interventions that reduce the health burden of environmental exposures. Christian is dedicated to combining research, policy advocacy, and public health practice to promote environmental health equity in low-resource settings.
