Professor Yanjia Cao received her PhD in Geography from University of Maryland, and MS in Geography from University at Buffalo-SUNY. As a health geographer, she had cross-disciplinary training in public health science during her postdoctoral scholarship, at Stanford University School of Medicine, Division of Infectious Diseases and Geographic Medicine, and also University of California San Diego, School of Public Health. Her current projects cover a variety of world-wide locations, concentrating on food environment and diabetes in San Diego, access to COVID-19 vaccine in England, and hospital facility functionality in Malawi. She serves board of directors (BOD) for the Health and Medical Geography specialty group at AAG since 2019. She was also the BOD member for the International Association of Chinese Professionals in Geographic Information Sciences during 2019-2020.
