- Email: asheikh@wuslt.edu
Dr. Sheikh specializes in bacterial pathogenesis, host-pathogen interactions, host responses, and vaccines, with a special focus on enteric bacterial pathogens including enterotoxigenic E. coli (ETEC).
Chen Shen, PhD
Assistant Professor of Medicine
- Phone: 314-273-3387
- Email: shenc@wustl.edu
Dr. Shen studies the structural mechanisms of host-pathogen interactions with an emphasis on the signaling involving NOD-like receptors and other pattern recognition receptors. The ultimate goal is to provide the molecular basis for the development of therapeutics targeting various infectious diseases.
Andrej Spec, MD, MSCI
Associate Professor of Medicine
- Phone: 314-454-8354
- Fax: 314-454-5392
- Email: aspec@wustl.edu
Dr. Spec‘s research is in fungal infections, particularly in immunocompromised patients, including those with transplants. His research focuses on Cryptococcus, Histoplasma, Candida, Aspergillus and other invasive molds. Dr. Spec also runs the division’s clinic focusing on invasive fungal infections, where he takes care of both immunocompromised and immunocompetent patients with fungal infections, which he considers the best and most rewarding part of his job.
Eva-Maria Strauch, PhD
Associate Professor of Medicine, Molecular Microbiology, Biochemistry and Molecular Biophysics
- Email: evas@wustl.edu
The main focus of Dr. Strauch's research is on how to diagnose, prevent and treat viral infections with the aim to generate new antivirals and candidates for vaccination through protein design.
Abby Sung, MD
Assistant Professor of Medicine (PEFA)
- Email: ASUNG@WUSTL.EDU
Dr. Sung recently completed a two year fellowship in ID. She will continue to stay on in ID to continue her work on outpatient infection prevention, occupational health and medical education.
Why did you choose WashU for your ID fellowship?
I chose WUSM for fellowship training because of: the flexibility in career paths (very accommodating for people who don’t know what specific realm of ID they want to pursue), the abundant research opportunities, the awesome people, being able to walk to work, the giant hospital with its wide array of disease pathology and large referral radius.
Larissa B. Thackray, PhD
Professor of Medicine
- Phone: 314-747-7976
- Email: lthackray@wustl.edu
Dr. Thackray specializes in basic research on RNA viruses with a specific focus on the role of the microbiome in host immunity and pathogenic outcome following systemic virus infection. She also uses model systems to characterize therapeutics and vaccines against emerging pandemic viruses such as SARS-CoV-2.
Barbara W. Trautner, MD, PhD
Gerald and Judith Medoff Professor of Infectious Diseases, Professor of Medicine, Co-Chief, Infectious Diseases Division
- Phone: 314-454-8354
- Email: trautner@wustl.edu
Dr. Trautner’s research focuses on diagnostic and antibiotic stewardship, particularly for urinary tract infections (UTIs). She has led trials to disseminate successful antibiotic stewardship interventions, improve the diagnosis and treatment of UTIs in men, develop bacteriophage therapy for UTIs in individuals with spinal cord injuries, and to reduce overdiagnosis of catheter-associated UTI.
Maria Cristina Vazquez Guillamet, MD
Associate Professor of Medicine
- Phone: 314-454-8215
- Email: m.c.vazquezguillamet@wustl.edu
Dr. Vazquez Guillamet’s main research interest is in infections caused by mutidrug resistant microbes in critically ill patients. She applies new methods to better stratify and predict the epidemiology, trajectories and outcomes of ICU patients at risk for MDR pathogens
