Ashley is a PhD student in the Department of Health, Behavior, and Society. Her work focuses on the health of people experiencing homelessness and public health governance. Prior to Hopkins, Ashley worked at the Centers for Disease Control and Prevention, where she led the Homelessness Unit in the agency’s COVID-19 Emergency Response. She led field deployments for COVID-19 outbreak investigations in homeless shelters and migrant decompression shelters and provided virtual support for mpox case investigation in correctional facilities. Ashley hopes to make social and behavioral sciences a core component of every outbreak response and integrate social conditions into public health surveillance. She received her MPH in Global Health and a Certificate in Religion and Health from Emory University’s Rollins School of Public Health and Candler School of Theology.

Kimberly is a third-year doctoral candidate in the Department of Population, Family and Reproductive Health. Her research interests lie in evaluating and improving the availability and quality of maternal and reproductive health services and interventions in resource-constrained settings. She applies mixed-methods research methods to enhance the understanding of 1) behavioral and psychosocial determinants of fertility and reproductive health outcomes among women and men, and 2) structural and health systems factors that shape access to and use of contraceptive services among adolescent girls and women. She is particularly interested in how trajectories of reproductive health evolve throughout the life course, from early adolescence through adulthood, and shape women’s and men’s overall health and psychosocial wellbeing. Currently, Kimberly is working on improving the measurement of women’s and men’s prospective pregnancy preferences by adapting the Desire to Avoid Pregnancy (DAP) scale for applications in low-resource and high-fertility settings in sub-Saharan Africa.
