Lauren Forrest

Assistant Professor
Research Interests: Clinical, Eating Disorders, Suicidal Thoughts and Behaviors, Applying Advanced Quantitative Methods to Clinical Science, Intersectionality, Multilevel Influences


My lab is dedicated to determining how suicide and eating disorders can be effectively predicted, treated, and prevented. We do this work because suicide and eating disorders are devastating. They affect millions of people worldwide, though the burdens are not felt equally across the population. Suicide and eating disorders disproportionately impact girls, women, and the LGBTQIA+ community. My lab conducts research to clarify particularly at-risk groups through an intersectionality lens, understand multilevel risk processes within these intersectional at-risk groups, and develop and disseminate effective interventions for these groups.

For example, my current eating disorders work investigates structural processes contributing to eating disorder prevalence at the intersection of gender, sexual orientation, and race. My current suicide work investigates multilevel and person-specific suicide risk processes at the intersection of rurality and sexual orientation. Suicide and eating disorders are incredibly complex, so much of my work uses advanced quantitative methods to capture and model this complexity.  Website

Dr. Forrest is interested in accepting new doctoral students for Fall 2024.
