Hello! My brief #introduction: I'm a professor of #economics and a #publicpolicy scholar at Rice U. I use #math modeling to inform science-based policy. I work on the economics of emerging infectious diseases, climate and the energy transition, and using #gametheory to study symbiotic relationships in #ecology. In #math I am interested in #topology and have studied #fixedpoint theorems for locally contractive set-valued maps. I enjoy travel, kayaking, reading, and dreaming of classic cars.
