Sten Vermund, MD, PhD


Dr. Sten Vermund is a pediatrician and infectious disease epidemiologist focused on diseases of low- and middle-income countries. His work on HIV-HPV interactions among women in Bronx methadone programs motivated a change in the 1993 CDC AIDS case surveillance definition and inspired cervical cancer screening programs launched within HIV/AIDS programs around the world. The thrust of his research has focused on health care access, adolescent sexual and reproductive health and rights, and prevention of HIV transmission among general and key populations, including mother-to-child. Dr. Vermund has become increasingly engaged in health policy, particularly around sustainability of HIV/AIDS programs and their expansion to non-communicable diseases, coronavirus pandemic response and prevention, and public health workforce development. His recent grants include capacity-building for public health in Chad, molecular epidemiology for HIV in Kazakhstan, and COVID-19 vaccine studies in Dominican Republic and Connecticut. He has worked with schools and arts organizations for COVID-19 risk mitigation and institutional safety.

Maggie Bartlett, PhD

Program Director

Dr. Maggie Linn Bartlett, a virologist at Johns Hopkins Bloomberg School of Public Health, specializes in emerging infectious diseases, focusing on RNA persistence and post-infectious conditions. Her groundbreaking work spans neurotropic viral diseases, post-viral syndromes, and immune-privileged zones. Utilizing multimodal sequencing and systems biology, she explored the resilience of bat immune systems to the filovirus Marburg. From addressing filovirus outbreaks at the United States Army Medical Research Institute of Infectious Diseases to studying B cell responses to SARS-CoV-2, Dr. Bartlett's expertise extends to alphaviruses, paramyxoviruses, and bunyaviruses. Her innovative multi-modal single-cell sequencing provides a holistic analysis of host-virus interactions, impacting therapeutic development and patient care. Dr. Bartlett's systems biology analyses identified potential biomarkers for neurotropic viral illness and are being explored for prognostic capacity in post-viral syndromes. Passionate about infectious disease mysteries, she investigates links between post-acute SARS-CoV-2 syndrome and post-viral illnesses, particularly in individuals with genetic connective tissue diseases. Dr. Bartlett's expertise in BSL-3/4 research and innovative methodologies positions her at the forefront of virology, reflected in recent grants for agnostic virus detection, therapeutics, and biomarker discovery.
