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 multimodal 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 position her at the forefront of virology, reflected in recent grants for agnostic virus detection, therapeutics, and biomarker discovery.
