Faculty Researchers
William Bishai, MD, PhD
William Bishai, MD, PhD is a Professor of Medicine, Pathology, and Molecular Microbiology and Immunology. He is the Co-director of the Johns Hopkins University Center for Tuberculosis Research. The William Bishai Laboratory studies the molecular pathogenesis of tuberculosis. The overall goal of our laboratory is to better understand tuberculosis pathogenesis and then to employ this understanding toward improved drugs, vaccines and diagnostics. Since Mycobacterium tuberculosis senses and adapts to a wide array of conditions during the disease process, it is clear that the regulation of expression of virulence factors plays an important role in pathogenesis. As a result, a theme of our research is to assess mycobacterial genes important in gene regulation. We are also interested in cell division in mycobacteria and the pathogenesis of caseation and cavitation.

Our research also includes ongoing studies of HIV and TB patients in Brazil and South Africa. Golub bio Johns Hopkins Center for Tuberculosis Research; Golub Research Dashboard and Publications
Amita Gupta, MD
Amita Gupta, MD is an Associate Professor of Medicine and the Deputy Director of the Johns Hopkins University Center for Clinical Global Health Education (CCGHE). The Amita Gupta Lab focuses on drug trials to prevent and treat HIV, tuberculosis (TB) and other co-morbidities in adults, including pregnant women and children who reside in low-income settings. We also conduct cohort studies assessing HIV, inflammation and nutrition in international settings; TB in pregnancy; and risk factors for TB in India (CTRIUMPH). We collaborate with several faculty in the Center for TB Research, Division of Infectious Diseases and the School of Public Health.

Christopher Hoffmann, MD, MPH
Christopher Hoffmann, MD, MPH is an Associate professor of Medicine. The Hoffmann Lab is focused on reducing TB and HIV morbidity and mortality in the low and middle income settings through behavioral and implementation science approaches. Work has focused on understanding individual-level behavior towards linkage to care and continued care engagement for HIV and TB and using this knowledge to develop approaches to increase HIV testing, linkage to care, HIV viral load suppression, and retention in care. Other work has focused on health system strategies to improve service delivery and improve adherence to best practice to guidelines-based care. The group’s research includes work on the general population, corrections inmates and ex-inmates, men at risk for HIV, and recently hospitalized individuals. Most of the research has been in South Africa and elsewhere in sub-Saharan Africa. Hoffmann bio Johns Hopkins Center for Tuberculosis Research; Hoffmann Research Dashboard and Publications

Petros Karakousis, MD
Petros C. Karakousis, MD is a Professor of Medicine. The Karakousis Lab is primarily focused on understanding the molecular basis of Mycobacterium tuberculosis persistence and antibiotic tolerance. A systems biology-based approach, including the use of several novel in vitro and animal models, in combination with transcriptional, proteomic, genetic, imaging, and computational techniques, is being used to identify host cytokine networks responsible for immunological control of M. tuberculosis growth, as well as M. tuberculosis regulatory and metabolic pathways required for bacillary growth restriction and reactivation.

Gyanu Lamichhane, PhD
Gyanu Lamichhane, PhD is an Associate Professor in the Division of Infectious Diseases, Department of Medicine, Johns Hopkins University School of Medicine. Investigating fundamental aspects of microbial life and leveraging the findings to develop clinically useful tools are equally emphasized in his research program. In 2012, he established a research program titled ‘Taskforce to study Resistance Emergence & Antimicrobial development Technology’ (TREAT).
Dr. Lamichhane’s current research focuses on identification and characterization of essential proteins of peptidoglycan biosynthesis and development of new antibacterials that work by interfering with this pathway. Peptidoglycan is the exoskeleton of bacterial cells without which bacteria cannot survive. The historical model of the peptidoglycan is narrow and does not adequately describe important aspects present in several clinically important bacteria. Dr. Lamichhane’s group focuses on the non-classical pathways for synthesis of peptidoglycan in mycobacteria.

Eric Nuermberger, MD
Eric Nuermberger, MD is a Professor of Medicine. Research in the Eric Nuermberger Lab focuses primarily on experimental chemotherapy for tuberculosis. We use proven murine models of active and latent tuberculosis infection to assess the effectiveness of novel antimicrobials. A key goal is to identify new agents to combine with existing drugs to shorten tuberculosis therapy or enable less frequent drug administration. We’re also using a flow-controlled in vitro pharmacodynamic system to better understand the pharmacodynamics of drug efficacy and the selection of drug-resistant mutants during exposure to current agents.
