Although Chi Hwan Lee works with flexible electronics technologies at the cellular and tissue scales, the collaborations he marshals to help advance and translate his innovative technologies operate on an international scale. The assistant professor of biomedical and mechanical engineering at Purdue University is a master collaborator. His partnerships span the globe, from South Korea, across the US, to the faculty member next door. He finds partners in industry, clinics, academia, the governments of two countries, and, serendipitously, while standing in line at Starbucks.
