About the Institute
The Johns Hopkins Lyme and Tickborne Diseases Research and Education Institute (LTBDI) is led by inaugural director Nicole Baumgarth, PhD, DVM. The Institute resides in the Bloomberg School’s Department of Molecular Microbiology and Immunology (MMI). Baumgarth leads the Institute’s research in four areas: vector/tick biology, epidemiology, microbiology, and host immune defense. The Institute focuses on research training and public outreach centered around the increasing threats of Lyme and other tickborne diseases to public health. In addition to Lyme disease, ticks play a role as carriers and reservoirs in over a dozen lesser-known diseases. Some, like Rocky Mountain spotted fever, are caused by bacteria, while others are caused by parasites or viruses.
Mission
Leading research and education on Lyme and other tickborne diseases to advance public health
Vision
To create a society in which an informed public will be protected from tick bites and the diseases they carry through education and provision of effective prophylaxes; and to ensure healthcare providers have access to improved and new diagnostics and therapies to better help those affected by a tickborne illness.

Boosting Immunity to Protect from Lyme Disease
Nicole Baumgarth's commentary on a clinical trial for a Lyme Disease vaccine was recently published in the Lancet Infectious Disease Journal.
New Faculty Member
We are excited to share that Dr. Thomas Hart is now an assistant professor in the department of Molecular Microbiology and Immunology as a part of the Lyme and Tickborne Diseases Research and Education Institute! He will be investigating mechanisms facilitating host infection and pathogenesis of tick-borne diseases, with a focus on Lyme disease.
To infect a human host, Lyme disease bacteria, Borrelia burgdorferi, must transition from the tick vector to the mammalian host. This transition exposes the previously tick-resident B. burgdorferi to new environmental pressures, such as a new immune system to avoid and new tissues to colonize. Dr. Hart uses fine scale molecular biology techniques and comprehensive systems biology approaches to examine the ways in which Lyme Borrelia sense and adapt to these new pressures to successfully infect the host and cause disease.
He received his Ph.D. in Biology from the State University of New York at Albany in conjunction with the New York Department of Health, and completed a postdoctoral fellowship at the Yale University School of Medicine in the labs of Dr. Erol Fikrig in infectious diseases and Dr. Aaron Ring in immunobiology.
He will be recruiting graduate students and postdocs in 2025. Learn more about Dr. Hart and his work by visiting his website!
Tickborne Diseases Research at Johns Hopkins
Johns Hopkins is home to several entities that focus on tickborne diseases research, diagnosis, and treatment.
In addition to LTBDI at the Bloomberg School of Public Health, the Lyme and Tickborne Diseases Dashboard, led by Frank Curriero at the Johns Hopkins Spatial Science for Public Health Center, harnesses the power of geography in tickborne diseases research.
In the Johns Hopkins School of Medicine, the Sherrilyn and Ken Fisher Center for Environmental and Infectious Diseases, led by Paul Auwaerter, is dedicated to the clinical research of environmental pathogens which improve the diagnosis and treatment of these infections. In addition, the Lyme Disease Research Center, led by John Aucott, is pioneering patient-based multidisciplinary research in all manifestations of Lyme disease.

Support the Lyme and Tickborne Diseases Research and Education Institute
The Institute welcomes and appreciates gifts of all kinds. Some donors choose to make a monthly contribution. Other members of our community, including those who have been impacted by Lyme and other tickborne diseases, give a one-time donation. All contributions to study and combat these vicious diseases are accepted with appreciation.
