She is also part of the Rutgers’ Institute of Health, Health Care Policy, and Aging. Her work focuses on how individuals’ gender, race, and class affect their mental health. She examines these effects on negative mental health problems like depression and on positive mental health such as happiness. She finds that gender, race, and class interact in paradoxical ways: certain disadvantaged groups have better mental health and happiness than those in more advantaged positions. Dr. Rosenfield proposes and investigates the explanations for these paradoxes.
