Oladele Ogunseitan, chair of UCI’s Program in Public Health, will temporarily join the U.S. Department of State later this year as one of 12 Jefferson Science Fellows. An expert on the environmental effects of industrial development and hazardous pollutants, Ogunseitan said he hopes to collaborate with federal officials on improving the regulation of toxic chemicals to enhance health in the U.S. and abroad. His yearlong fellowship, which begins in mid-August, will take him to Washington, D.C., and possibly overseas. The Jefferson Science Fellowship program brings together cutting-edge academic expertise in science, technology, medicine and engineering to help shape U.S. foreign policy.
