Dr. Lightfoot received her master’s and doctorate in Counseling Psychology from UCLA. Her research focuses on improving the health and well-being of adolescents and young adults, as well as the development of culturally competent, efficacious interventions to reduce acquisition and transmission of HIV among populations disproportionately burdened by the epidemic. She has obtained NIH funding to design and implement HIV preventive interventions, including culturally-tailored interventions for adolescents in the juvenile justice system, runaway/homeless youth, youth living with HIV, young MSM, and adults living with HIV. Her research has developed interventions and bridged the gap from development to implementation. She has been the Principal Investigator on numerous R01 and other R-level grants, as well as center grants and foundation grants, including from the Robert Wood Johnson Foundation, William T. Grant Foundation, and others. She has had a distinguished career in community-engaged research, receiving awards for her community partnership efforts.
