September 15
Cecilia Sem Obeng, PhD (IU School of Public Health-Bloomington)
Dr. Obeng's session is titled "Human Milk Banking: A Pathway to Combat Infant Mortality." This presentation will highlight:
- The Biological Edge: Discover how donor human milk acts as a unique "biological barrier" that formula cannot replicate, serving as a critical medical intervention to prevent neonatal death in the world’s most vulnerable infants.
- The Ghana Milestone: Learn about the design and implementation of Ghana’s first human milk bank, a strategic safety net developed to combat high infant mortality rates by providing a life-saving resource when maternal milk is unavailable.
- The Justice Lens: Join the conversation on why access to human milk is a fundamental matter of justice, and how scaling milk banking can bridge the survival gap for marginalized communities across Sub-Saharan Africa. A brief Q&A will follow.
Dr. Obeng is professor in the Department of Applied Health Science and the founding director of the Maternal and Child Health (MCH) program at the Indiana University School of Public Health-Bloomington. She is also the initiator, designer, and sponsor of the first human milk bank in Ghana, which was inaugurated on June 12, 2025. Dr. Obeng's work primarily focuses on maternal and child health, particularly infant feeding (breastfeeding), and the health of immigrant families. She has published several peer-reviewed articles and books on MCH and has given over 100 academic, professional, and scientific presentations on the topic. She has been an invited speaker to talk about breastfeeding at conferences. Dr. Obeng spearheaded the Breastfeeding Scaling Up Project (BSP), which focuses on training the next generation of breastfeeding educators in a public health school. She has several years of research experience conducting community-based breastfeeding research in African-American communities and has facilitated breastfeeding workshops for parents in Indiana. Dr. Obeng has received numerous grants and awards for her work in maternal and child health and qualitative research. Specifically, she has secured ten teaching grants and awards, three awards for mentoring students, one award for her contributions to women's issues, and another for her qualitative research work. Dr. Obeng is the 2025 recipient of the John W. Ryan Award for Distinguished Contributions to International Programs and Studies. She has trained over 150 students in qualitative research methodologies.

Alka Khaitain, MD (IU School of Medicine)
Dr. Khaitan is an associate professor of pediatrics at Indiana University School of Medicine and fellowship program director for the Ryan White Center for Pediatric Infectious Diseases and Global Health. She is a clinician, educator and physician-scientist. Dr. Khaitan is dedicated to diagnosing and managing infectious diseases in children and cares for patients at Riley Hospital on the General and Immune Compromised Pediatric Infectious Diseases Services. She also provides care for patients with childhood infections and children exposed to and living with HIV in the Riley Outpatient Center. In her role as fellowship program director, she is committed to training the next generation of pediatric infectious disease physicians.
Dr. Khaitan’s research focuses on pediatric HIV, immunology and global health. She aims to better understand the role of inflammation and T cell exhaustion in pediatric HIV pathogenesis and long-term outcomes. She is the Principal Investigator of NIH-funded studies focused on immunopathogenesis in Kenyan children with perinatal HIV. Her work highlights early and persistent inflammation and a myriad of other immune disruptions in children with perinatal HIV, despite successful antiretroviral treatment. She has ongoing collaborative studies to identify immune biomarkers of neurodevelopmental outcomes in children with perinatal HIV exposure.
Dr. Khaitan leads the Riley Hospital Multisystem Inflammatory Syndrome in Children (MIS-C) Task Force and serves on the Indiana University COVID-19 Treatment Algorithm Committee. She is a member of the HHS Panel on Antiretroviral Therapy and Medical Management of Children Living with HIV, Co-Chair of the International Maternal Pediatric and Adolescent AIDS Clinical Trials (IMPAACT) P2008 ("Phase I/II multisite, randomized, controlled study of monoclonal antibody VRC01 with combination antiretroviral therapy to promote clearance of HIV-1-Infected cells in infants") and an Immunologist on IMPAACT P2028 (“Long-Term Clinical, Immunologic, and Virologic Profiles of Children who Received Early Treatment for HIV Infection”).
