Faculty Profile

James Bina, PhD

The Bina lab studies mechanisms of antimicrobial resistance and bacterial pathogenesis in the gram-negative pathogens Vibrio cholerae and Klebsiella pneumoniae. The long-term goal of our studies is to define the underlying processes that allow bacteria use to cause disease and resist antibiotics.


Jieshi Chen

Ms. Jieshi Chen is a senior research analyst in the Auton Lab at the Robotics Institute,  Carnegie Mellon University. She is specialized in applying machine learning techniques to detect and characterize anomalous patterns in massive scale temporal transactional data in healthcare informatics, financial industry and other domains.


Vaughn S. Cooper, PhD

The mission of the Cooper laboratory is to translate evolutionary biology to improve human health, empower K-12 education, and reveal the origins of biodiversity. Specifically, we study the evolution, ecology, and genome dynamics of experimental and clinical microbial populations.


Yohei Doi, MD, PhD

Dr. Doi is the Director of Center for Innovative Antimicrobial Therapy at the University of Pittsburgh. The mission of Dr. Doi’s laboratory is to identify and investigate antimicrobial resistance of clinical concern among gram-negative bacterial pathogens. The areas of research include the genetic and molecular basis of emerging antimicrobial resistance mechanisms; the rapid diagnosis of resistance using phenotypic, genetic, and lipidomic approaches; and inhibitor-based drug discovery. Current efforts are focused on colistin resistance in Acinetobacter baumannii, a problematic healthcare-associated pathogen, and fosfomycin resistance in Escherichia coli, the predominant cause of urinary tract infection in both healthcare and community settings. The latter work has expanded into drug discovery effort aimed at reversing resistance using an inhibitor-based approach.

Artur Dubrawski, PhD

Artur Dubrawski is a Research Professor at Carnegie Mellon University Robotics Institute where he directs the Auton Lab, a research group of 80+ focusing on fundamental and applied research on machine learning. Dr. Dubrawski has three decades of R&D experience; he has served in executive roles in high tech industry and as a principal investigator on several projects into artificial intelligence for a range of government industrial partners.

Faculty Profile

Elise Martin, MD, MS

As the Medical Director of Infection Prevention and Hospital Epidemiology at VAPHS, Dr. Martin is most interested in quality improvement research in infection prevention and finding ways to decrease the spread of hospital acquired pathogens and resistant organisms. She is very interested in how we use personal protective equipment and isolation to decrease the spread of infections, while trying to maintain high quality patient care. Most of her research focuses on contact precautions and hospital adverse events. She is also interested in infection prevention in dialysis, CLABSI, and medical education.

Faculty Profile

Barbara Methé, PhD

Dr. Methé is the Director for the Center for Medicine and the Microbiome and a Visiting Professor of Medicine. Dr. Methé has extensive experience in genomics, metagenomics, microbial ecology and physiology and handling large data sets from high throughput functional ‘omics-enabled methodologies. She has led numerous annotation and comparative genome analyses of diverse prokaryotes and has developed and applied multi-omics approaches to the study of microbial communities from diverse environments including freshwater, deep subsea floor and groundwater systems, to plants, animals and humans. She was one of the leaders of the NIH supported Human Microbiome Project (HMP), a multi-organization effort focused on systems biology approaches to study microbes of the adult human body and has continued to study the human microbiome in a variety of contexts including psoriasis and lung disease.
