In 2010 he was awarded the Maternal and Child Health Bureau’s Vince Hutchins Award “…to a lifetime of distinguished service to improve the health of MCH populations.” Contact Dr. Blum.



Caroline Moreau, MD MPH PhD – Co-Principal Investigator

Caroline Moreau, MD MPH PhD, is the Robertson Chair and Assistant Professor at the Johns Hopkins Bloomberg School of Public Health. Strongly dedicated to women’s sexual and reproductive health, she has led a number of sexual and reproductive health research projects at institutions including the Johns Hopkins Bloomberg School of Public Health, Princeton University, and the National Institute of Health and Medical Research (INSERM) in France. Her work has especially focused on advancing the understanding of contraceptive use patterns over time and its association with unwanted fertility and abortion rates. She is particularly committed to working in a multidisciplinary environment which has shaped her thinking by linking social science concepts and statistical methods to develop a better understanding of the processes underlying sexual and reproductive health behaviors and outcomes. In this perspective, she is currently involved with colleagues at Hopkins in a project applying agent based modeling to simulate the effects of family planning interventions on fertility outcomes. Over the last 3 years at INSERM, she has been co-PI of the last national survey on sexual and reproductive health in France conducted in 2010 (n=8,645 participants) that explores sexual and reproductive health as a process resulting from social and medical factors that inform individuals’ attitudes and behaviors. The project has also served as a platform to advance survey methodology, to investigate the feasibility, value and limitations of conducting national fertility surveys online. Working closely with colleagues at Princeton University, INED (Institut National d’Etudes Démographiques), she places a strong emphasis on cross national-comparative approaches to reproductive health issues.

Kristin Mmari, DrPH – Lead Qualitative Researcher

Kristin Mmari, DrPH is an Assistant Professor in the department of Population, Family and Reproductive Health at the Johns Hopkins Bloomberg School of Public Health. With a degree in medical anthropology, she has extensive training in both qualitative and cross-cultural research. She has been conducting qualitative and cross-cultural research for nearly 15 years, and has used these methods for both research inquiry and evaluation purposes. Recently, Kristin completed one of the largest cross-cultural qualitative studies on adolescent health. For this study, known as the WAVE study (Well-Being of Adolescents in Vulnerable Environments), she was the lead qualitative investigator and was responsible not only for designing all of the qualitative data instruments across 5 global sites (which included Shanghai, New Delhi, Johannesburg, Ibadan, and Baltimore), but was also responsible for developing a coding and analysis protocol so that data from across the different sites could be compared and contrasted systematically. This consisted of qualitative data from 100 key informant interviews; 100 in-depth interviews among youth; and 40 focus groups among youth across the sites. Her experience with this project as well as other qualitative studies conducted among diverse populations of adolescents, including American Indian, Tanzanian, Zambian, and inner city youth in Baltimore, will provide a strong and solid basis for conducting Phase 1 of the GEAS. For the GEAS, Kristin will be responsible for helping to design the qualitative data collection instruments, training research assistants to conduct the in-depth interviews and group interviews, and will be supervising the coding process and analysis of the qualitative data.

Amanda Latimore, PhD – Director of Data and Analytics

Amanda Latimore is a social epidemiologist and faculty at Johns Hopkins Bloomberg School of Public with a joint appointment in the Departments of Population, Family and Reproductive Health and Epidemiology. Her primary interests are the social, psychological and contextual factors that contribute to disease and disorders, particularly in urban youth.  While completing her doctoral training at the Johns Hopkins Bloomberg School of Public Health in the department of Epidemiology, Dr. Latimore developed a data-informed, agent-based simulation of sexual behavior to demonstrate the impact of community gender ratios on the high-risk partner selection of inner-city females.  She is currently involved in evaluating a community-based mental health intervention for high-risk youth in Baltimore and conducting multilevel analyses of a state-wide home visiting program. She is also part of a  Baltimore City-wide collaboration to address the needs of disconnected youth through multi-agency systemic change.


Lydia Animosa, MSPH – Research Program Coordinator

Lydia Animosa received a Master of Science in Public Health degree from the Johns Hopkins Bloomberg School of Public Health Department of Population, Family, and Reproductive Health. As a student, she interned at the Johns Hopkins School of Medicine in the Department of General Pediatrics and Adolescent Medicine where she led a qualitative study of risk behavior involvement and future orientation among adolescents in Baltimore, looking closely at which ecological factors motivated youth to transition away from involvement in risk behavior. Before coming to Baltimore, Lydia was a service fellow with Volunteers in Asia and worked as an English teacher at the Guangzhou English Training Center for the Handicapped, a junior college for youth with physical disabilities in Guangzhou, China. She is the GEAS program coordinator and as such enjoys working with researchers at each site to move the study forward for the betterment of adolescent health around the world. Contact Lydia.


Anna Kågesten, MPH  Research Assistant

Anna Kågesten received her MPH in epidemiology from the Johns Hopkins Bloomberg School of Public Health and has a BSc. in public health and gender studies from University of Gothenburg. She came to the US from Sweden as a Fulbright grantee in 2011 and is now a PhD student within the Department of Population, Family and Reproductive Health. As a PhD student, she blends training in social epidemiology and qualitative methods, focusing on international adolescent reproductive health. She is especially interested in the gender influences on sexual decision-making and access to comprehensive adolescent health services including contraceptives. Anna has over 6 years of professional experience in the design and implementation of ASRH programs, ranging from the implementation of comprehensive sexual health programs in Swedish schools, to the understanding of coping strategies among youth HIV peer educators in South Africa. Her past research has explored determinants in sexual debut in Sweden, teenage pregnancy in urban poor environments through the Well-being of Adolescents in Vulnerable Environments (WAVE) study; men’s fertility intentions in France; and the quality of comprehensive adolescent health programs that improve sexual and reproductive health. She is a consultant to the WHO on program reporting standards and led the youth component of the 3rd International Conference on Family Planning, which brought together 3,300 world leaders, NGOs, donors and youth leaders under the age of 25. Anna has been working as a research assistant for the Global Early Adolescence Study for the past two years, and will develop her dissertation around Phase 1.
