Emily Arnold, PhD, MPH
Associate Professor, Department of Medicine Dr. Arnold’s research agenda is primarily devoted to reducing HIV-related health disparities for African American men who have sex with men, with a strong emphasis on community collaborative research designs and building HIV-prevention intervention programs. As an anthropologist, Dr. Arnold has a great deal of experience in conducting and teaching others to do qualitative and mixed methods research and she has worked with various research teams, as well as post-doctoral research fellows, international trainees, graduate students, medical students, and community members to implement these research designs. Building community collaborative partnerships have been an essential part of Dr. Arnold’s research agenda, from the point of forming community advisory boards to weigh in on data collection instruments to disseminating findings back to community members. Her current studies include testing an HIV-prevention intervention for African American men who have sex with men and women using a randomized controlled trial, developing an intervention to promote sexual health through social networks among sexual and ethnic minority youth involved in house ball communities and gay families, understanding barriers to integrate behavioral health and HIV-related services for people with severe mental illness, and several policy-related studies on the impact of a changing health care delivery system on PLWHA and the agencies that serve them.

Cherrie B. Boyer, PhD
Professor of Pediatrics, Division of Adolescent Medicine Dr. Boyer is a Professor of Pediatrics based in the Division of Adolescent and Young Adult Medicine where she serves as the Associate Division Director for Research and Academic Affairs. She is an internationally recognized health psychologist with nearly 30 years of research experience in the area of adolescent and young adult health. Dr. Boyer has been the recipient of many grant awards and has been a productive investigator, publishing widely in the area of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) prevention in adolescents and young adults. Her program of research focuses on the development and evaluation of cognitive-behavioral and community-level intervention strategies utilizing both culturally competent and positive youth development frameworks to promote sexual health and to reduce the risk of STIs, HIV, and unintended pregnancy and their sequelae in adolescents and young adults (youth). Such interventions have been implemented in various groups, including high school students, teen and STD clinic patients, among at-risk youth residing in high STI prevalent urban neighborhoods, and military personnel, both domestically and internationally. Moreover, for the past 10 years, Dr. Boyer was a member of the NIH-funded Adolescent Trials Network (ATN) where she served as a lead investigator and collaborated on a number of community-based participatory research community mobilization studies to examine social determinants and structural barriers to improve HIV prevention for at risk youth and linkage, engagement and retention in long-term HIV healthcare for HIV-infected youth. She is currently working with the San Francisco Department of Public Health, Community Health Equity and Promotion Branch to conduct community-engaged research to better understand social determinants associated with increased rates of STIs in San Francisco youth with the end goal of designing age-appropriate and culturally-tailored prevention strategies to reduce their risk and acquisition of STIs.

He is PI of five NIH-funded studies evaluating the efficacy of combination interventions (pharmacologic agents with counseling modalities) among substance-using populations. In addition, he is interested in evaluating the impact of alcohol and substance use on HIV treatment and care among HIV-positive individuals. Dr. Santos is also a Senior Research Scientist at the San Francisco Department of Public Health. In addition to serving as a mentor with the Visiting Professor program, Dr. Santos is co-director of the Traineeship for AIDS Prevention Studies post-doctoral program and is a faculty mentor for multiple UCSF training programs, including the Biobehavioral Research Program in Symptom Science, the Postdoctoral Traineeship in Substance Use Disorders Treatment and Services Research, the National Clinician Scholars Program, and a summer program for underrepresented minority undergraduate students.

James L. Sorensen, PhD
Professor In Residence, Department of Psychiatry Dr. Sorensen began work in substance abuse treatment research more than twenty-five years ago, directing a National Institute on Drug Abuse (NIDA)-funded double-blind investigation of detoxification from heroin. He developed and evaluated a community network approach to drug abuse treatment, assessed family therapy’s efficacy with methadone maintenance patients, tested the efficacy of small-group HIV education with drug users, evaluated the impact of case management for substance abusers with HIV/AIDS, investigated the utility of treating methadone maintenance patients in a therapeutic community, and conducted several studies of how to help people who inject drugs to better adhere to their HIV medications. Dr. Sorensen also leads the Western States Node of the NIDA Clinical Trials Network and a NIDA T32 training program in substance use treatment research. His research has focused on how to improve the treatment that we provide to people with substance use disorders. Click here for more information on Dr. Sorensen.
Sonya Arreola, PhD, MPH
Consultant Dr. Arreola is a clinical psychologist and epidemiologist by training with expertise in community-based participatory action research, education, and advocacy focused on the sexual health of sexually and ethnically marginalized groups.

She has served as principal investigator of federally funded and foundation-funded studies focused on sexual health among marginalized populations. Her research projects include development of sexual health theory regarding how sexual stigma, sexual initiation, and other contextual and sociocultural factors conspire to create unhealthy conditions for Latino gay men in adulthood along with the resiliency factors that ameliorate the negative consequences of these conditions; a mixed-methods study on the structural factors that impact the sexual health of migrant day laborers; and global community-based mixed methods study exploring barriers and facilitators of access to HIV services as well as the development of a sexual health theory among gay men and other men who have sex with men.
