About Us

The Division of Infectious Diseases, part of the Department of Medicine, is composed of two sections led by two highly distinguished co-directors who work closely together to ensure a fully-integrated multidisciplinary program.



William Powderly, MD, the J. William Campbell Professor of Medicine, leads the clinical section, which manages the patient care, graduate and post-graduate medical education, and clinical research missions of the Division. Dr. Powderly is the Larry J. Shapiro Director of the Institute for Public Health and the director of the Institute of Clinical and Translational Sciences (Washington University’s CTSA)







Jennifer Philips, MD, PhD, heads the basic sciences research mission of the Division. Dr. Philips has been recognized with the Maxwell Finland Award for Excellence in Research and The Astellas Young Investigator Award, She is a member of the American Society of  of Clinical Investigation (ASCI) and is a Fellow of the American Academy of Microbiology.  Dr. Philips’ research focuses on Mycobacterium tuberculosis virulence factors, metabolism and immunology.

Dr. Philips is known for her scientific accomplishments, her collaborative leadership style, and commitment to mentoring the next generation of infectious disease physicians and scientists.

Researchers within the division have contributed to advances in the basic understanding of infectious diseases as well as in the identification and establishment of better care practices that have led to better patient outcomes.

The laboratories of the Division are heavily engaged in basic science research encompassing the study of pathogenesis and host defense in infectious diseases using an array of methodologies drawing from:

  • Molecular biology
  • Biochemistry
  • Genetics
  • Genomics
  • Immunology
  • Cell biology

Clinical research

Clinical research within the Division includes translational research as well as areas such as:

  • Epidemiology
  • Health services
  • Outcomes
  • Patient safety

Patient care

The patient care and research programs of the Division are closely allied with the following:

These groups share joint clinical and research conferences and offer a wide range of elective clinical and research rotations. Several members of the faculty have joint appointments in more than one department, and several of our fellows have been trained in both pediatric and adult infectious diseases.

Collaboration across divisions and departments is highly encouraged and opportunities abound for mentored clinical and laboratory-based research at the Washington University School of Medicine.
