We at the Center for Research on Families (CRF) at UMass Amherst were deeply saddened to learn that Louis Graham passed away suddenly on December 29, 2019. Louis was a former Family Research Scholar from 2016-2017, a member of our Stress Research Group, and a member of the Public Engagement Project. His research focused on understand the psychological determinants of mental and sexual health among ethnic minorities and sexually marginalized groups - including depression, anxiety, and HIV prevention among black and Latino gay and bisexual men and transgender women. He used community based participatory approached to facilitate power sharing amongst community stakeholders. Louis was committed to his work and a valued member of the communities he served. His passion, drive, and kindness will be missed. We will remember Louis for his important contributions to the field and for his advocacy.
