Tonda Hughes, PhD, RN, FAAN

  • Professor Emerita

Dr. Hughes has a distinguished career focusing on women’s mental health and substance use (total funding exceeding $20 million USD). She is well known for her ground breaking work in the 1980s related to chemically dependent nurses, and is a nationally and internationally recognized expert in the area of alcohol use among sexual minority (lesbian and bisexual) women.  Her pioneering studies on the predictors and consequences of alcohol use among sexual minority women have received continuous funding since 1999 from the U.S. National Institutes of Health and other sources and have grown into the world’s longest running longitudinal study of alcohol use and health among sexual minority women. She has served as Co-Investigator on numerous other funded studies with researchers from major U.S. and Australian institutions, including the University of Melbourne and Deakin University. Dr. Hughes holds Honorary Professor appointments at the University of Technology-Sydney and Deakin University (Australia), Oxford Brookes University (Oxford, England) and the University of Pennsylvania.

Current Area of Teaching

Dr. Hughes supervised masters, doctoral and postdoctoral students/fellows, and international visiting scholars. Most recently she taught Global Health Nursing for UIC and international undergraduate students. Prior to assuming her previous administrative role as Head of the Department Health Systems Science, she taught graduate core courses in the UIC Interdisciplinary Women’s Health Concentration. She participated in more than a dozen training grants and served as mentor or consultant to numerous researchers at UIC, throughout the US, and in Canada, England, India, Japan, Thailand, Rwanda, South Africa, South Korea, Australia and New Zealand.

Hughes served as primary or national mentor for three Robert Wood Johnson Faculty Nurse Scholars. In addition, she was co-investigator/co-director of the UIC Building Interdisciplinary Research Careers in Women’s Health (BIRCWH), NIH Office of Research on Women’s Health, K12 HD055892, 2007-2017 and was part of the leadership team for a National Institutes of Health and Fogarty International Center, D43 (PI, S. Weine). This project focused on building research capacity in low- and middle-income countries concerning the major global health problem of migration-related non-communicable diseases.
