Rebecca Richards-Kortum’s research and teaching focus on developing low-cost, high-performance technology for low-resource settings. Her group is developing miniature imaging systems to improve early detection of oral, esophageal, and cervical cancer and their precursors and has integrated advancements in nanotechnology and microfabrication to develop low-cost sensors for infectious diseases at the point-of-care. Richards-Kortum also founded the Beyond Traditional Borders (BTB) program, in which undergraduate students from multiple backgrounds learn to think beyond geographic and disciplinary boundaries to solve challenges in global health.
