John Metcalfe

John Metcalfe is a Professor In Residence in the Department of Pulmonology at Zuckerberg San Francisco General Hospital (ZSFG), part of the University of California, San Francisco (UCSF) School of Medicine. His email contact is john.metcalfe@ucsf.edu.

Dr. Metcalfe has a particular interest in the clinical management of multidrug resistant tuberculosis (MDR-TB) in high HIV burden settings in Southern Africa. His research includes the development of non-invasive pharmacokinetic measures to enhance MDR-TB drug development and clinical trials. He is a member of the AIDS Clinical Trials Group TB Transformative Science Group and has specialized training in epidemiology, statistical prediction, and diagnostic test evaluation. Dr. Metcalfe serves as a specialty editor for respiratory diseases at PLoS Medicine.

His research focuses on several critical areas within tuberculosis:

• Drug-resistant tuberculosis diagnostics and treatment
• HIV-TB co-infection management
• Pharmacokinetic monitoring using novel methods like hair sampling
• Genomic analysis of drug resistance mutations
• Development of improved diagnostic tools for tuberculosis

Analysis of Dr. Metcalfe's recent publications reveals a strong emphasis on genomic approaches to understanding and detecting drug resistance in tuberculosis. His work frequently employs next-generation sequencing technologies and novel molecular diagnostic approaches. There's a clear focus on practical applications in resource-limited settings, particularly in Southern Africa where HIV-TB co-infection is prevalent. His research increasingly incorporates innovative methods like hair sampling for therapeutic drug monitoring and the development of more accessible diagnostic tools.

Dr. Metcalfe has contributed significantly to several important areas of tuberculosis research:

• Development of LC-MS/MS panels for quantifying drug-resistant TB medications in small hair samples
• Investigation of bedaquiline resistance mechanisms and detection methods
• Studies on the prevalence and management of drug-resistant TB in Zimbabwe and South Africa
• Research on chronic lung disease following tuberculosis treatment
• Validation of novel diagnostic approaches for tuberculosis

Dr. Metcalfe's work has involved collaboration with numerous research groups across Africa and the United States. His research has been supported by various grants focused on tuberculosis diagnostics, treatment, and epidemiology. He has contributed to important policy discussions regarding tuberculosis management in high HIV burden settings and has been involved in clinical trials evaluating new approaches to drug-resistant TB treatment.

His laboratory and research team focus on translational tuberculosis research, bridging the gap between basic science discoveries and clinical applications. The team employs a range of techniques from molecular biology to epidemiology to address critical challenges in tuberculosis control, particularly in settings with limited resources.
