Institute Fellows
Cohort 1
 Michelle Broaddus, Ph.D., is an Assistant Professor at the Center for AIDS Intervention Research (CAIR) at the Medical College of Wisconsin. Her research has been guided by the study of gender roles, how individuals negotiate condom use within relationships, and contexts of sexual risk among high-risk young adults and adolescents. She obtained her Ph.D. in social psychology at the University of Colorado at Boulder in Social Psychology in 2008, focusing on condom attitudes and gender and power in heterosexual relationships. She has published articles examining associations with consistent condom use and the effects of a HIV risk reduction randomized controlled trial among adolescents in detention, detailing gender specific models of condom use intentions and use among adolescents on probation, and perceptions of condom proposers among college students. She completed a NRSA postdoctoral fellowship at CAIR in 2010, and conducted a developmental project on the uses of social media technology, including Short Messaging Service (SMS, also known as “texting”) in sexual relationships among HIV and STD at-risk young adults. After being hired as an assistant professor at CAIR in 2010, Dr. Broaddus’s interests remain focused on the potential for mobile phone technologies in innovative HIV prevention interventions, both as a medium for intervention delivery, and as a tool for at-risk populations to increase safer sex communication. The expansion of “Web 2.0,” in which people both actively consume and produce content, challenges some fundamental concepts that guide ethical decisions made by IRBs. In online and mobile environments, the concept of “privacy pragmatism,” or the belief that people weigh concerns about possible intrusions into privacy against the inherent benefits of sharing personal information, challenges the rubric of costs and benefits currently used by IRBs. Dr. Broaddus aims to explore these issues during her time as a RETI fellow.

 Peter Davidson received his Ph.D. in medical sociology from the University of California, San Francisco in 2009. Dr. Davidson has been conducting research and harm-reduction based intervention development around heroin-related overdose and the transmission of HIV, hepatitis C, and sexually transmitted infections among drug users in Australia and the United States since 1997. Dr. Davidson's dissertation project explored the influence of policing practices on the movements and economic activities of a highly mobile group of homeless younginjecting drug uses in San Francisco, and how these in turn affect the willingness and ability of young injectors to utilize needle exchange services. His work also involves explorations of how injecting drug users and other economically marginalized populations ‘make sense’ of research participation, and the ethical implications of these understandings.

Kristin Kostick, Ph.D.
 Dr. Kristin Kostick is a medical anthropologist with expertise in applied prevention/ intervention research, with specific experience in HIV/AIDS prevention and interdisciplinary research methods. She specializes in the design and implementation of culturally-specific and community-based health interventions, including those aimed at reducing sexual risk and promoting psychosocial health and gender equity. She has engaged in training and capacity-building among local non-governmental and community-based organizations in developing countries, particularly among impoverished urban slum communities in India and Mauritius. She has also conducted evaluation research on evidence-based research programs, including Supported Employment rehabilitation services for individuals with severe mental illness in the US, and malaria control interventions in West Africa. Dr. Kostick has experience collaborating with both local and national entities, and coordinating research activities across academic and clinical settings. Her methodological approach combines mixed qualitative and quantitative methods, including ethnographic research techniques ranging from structured and unstructured interviewing with individuals and focus groups to participant observation. She is also trained in psychometric research methods, including statistical analysis, scale construction, and survey research methods, and in social network analysis related to peer relationships and psychosocial well-being. Her current research focuses on the role of MDMA (ecstasy) –use on sexual risk behaviors among urban young adults, as well as the use of ecstasy to improve intimacy, communication and sexual satisfaction in relationships characterized by significant intimate partner conflicts. In conjunction with her previous work in India, she continues to focus on culturally-based symptom markers that can help to identify women who are in relationships whose dynamics put them at greater risk for HIV and other sexually transmitted infections. Dr. Kostick has conducted research in India, Africa, Mauritius and the US, and is conversational in French.

Cynthia Pearson, Ph.D.
 Research Assistant Professor Cynthia R Pearson directs the Research Methods and Policy Core at the Interdisciplinary Indigenous Wellness Research Institute where she collaborates with indigenous scholars in the development of research policies and directs iterative data analysis on historical and cultural determinants of physical and mental health among American Indians and Alaska Natives. Dr. Pearson expertise is in designing community-based health studies from an ecological perspective that emphasize social, economic, political, environmental, and historical determinants of health. Specifically, Dr. Pearson’s research focuses on the intersecting risk of substance use, historical and lifetime trauma, and HIV risk and how culture, place, and community serve as protective factors. Dr. Pearson meets community members where they are and identifies community ways of knowing and resources to create innovative sustainable interventions. She is involved in several CBPR health and wellness projects across Pacific Northwest tribal communities identifying strengths and protective factors that support young women’s wellness, maternal health, cardiovascular disease, youth academic achievement, and suicide prevention.

 Elizabeth Reed, MPH, ScD is an Assistant Professor at George Washington University School of Public Health in the Department for Prevention and Community Health. Her research has focused on gender-based violence (GBV) and HIV prevention in multiple global settings, with particular attention to the influence of social, environmental, and structural factors on risk (e.g. economic position, gender inequities and norms, other challenges across individuals’ ‘life contexts’). Given the increasing recognition that such contextual-level factors are contributing significantly to these health burdens and thereby, the need for interventions that aim to alter such structures within communities, Dr. Reed’s research agenda focuses on the development, implementation, and evaluation of structural-level interventions to address GBV and HIV –particularly those that consider both social and economic aspects of women’s lives. Given the contribution of GBV to HIV risk across populations and contexts, her work related to GBV prevention is also central to HIV prevention. Dr. Reed’s recent work in the US has involved investigation of social and environmental contexts in relation to GBV perpetration, as well as the mechanisms explaining the link between such perpetration and STI/HIV risk. Her most recent work abroad has involved the investigation of social and environmental factors (e.g. residential instability, economics, migration/mobility, forced migration) and relation to vulnerability for GBV and HIV risk among women working as sex workers in South India.

Lianne Urada, Ph.D., LCSW
 Lianne Urada is a postdoctoral scholar in the Division of Global Public Health, UCSD Department of Medicine, with a PhD in Social Welfare from UCLA (March, 2011), and a former doctoral training fellow in the Social and Behavioral Determinants of HIV/AIDS Prevention in the Department of Community Health Sciences, UCLA School of Public Health. She also worked with persons living with HIV/AIDS for eight years in Los Angeles, California. She served as a Field Education faculty member in Social Welfare at UCLA and holds a California license in clinical social work. For her dissertation, she conducted surveys of 498 female entertainment workers and 48 managers from 54 establishment venues (night clubs/bars, spa/saunas, karaoke bars) in the Philippines. She received grants to assess the socio-structural influences of risk behavior among the entertainers and to develop and evaluate a new intervention. The Philippines is a predominately Catholic country with a growing HIV prevalence. Specifically, she examined factors in the risk environment (at physical, social, economic, and policy levels) and their effects on behavioral outcomes. She used a mixed method, collaborative community-based research approach. She also interviewed 48 key informants (health officials, managers, NGOs) and held focus groups of entertainers prior to administering questionnaires. Dr. Urada wishes to examine the ethics surrounding research with sex workers in the Philippines who are concerned about their legal risks and human rights. The criminal contexts of substance use, sex work, and trafficking often pose perceived risks to participants. Interviews with policymakers, law enforcement, and establishment managers regarding police practices in relation to sex workers and substance users are necessary. Prior ethics inquiry may help facilitate sex worker interventions and minimize the risks involved.
