Russell E. Lewis, PharmD, FCCP, BCPS
Associate Professor
Department of Clinical Sciences and Administration
University of Houston College of Pharmacy
University of Texas M. D. Anderson Cancer Center
Houston, Texas


Russell E. Lewis received a PharmD from the University of Kansas. He completed a pharmacy residency at Barnes Jewish Hospital, Washington University and a residency in infectious diseases at the University of Iowa College of Pharmacy in Iowa City. At the University of Texas M. D. Anderson Cancer Center (MDACC), Dr. Lewis currently spends 4 months on the Infectious Diseases Consultation Service, which focuses on hematological malignancies and hematopoietic cell transplantation.

Dr. Lewis is a board-certified pharmacotherapy specialist with added qualifications in infectious diseases. He is involved with several professional societies, holding membership in the American Society for Microbiology, International Society for Anti-Infective Pharmacology, American College of Clinical Pharmacy, American Association of Colleges of Pharmacy, Society of Infectious Diseases Pharmacists, and the American Society of Health-System Pharmacists.

Dr. Lewis has authored or coauthored over 85 peer-reviewed publications in the area of antifungal pharmacology and immunology. His laboratory was the first to describe the in vivo pharmacodynamics of amphotericin B and caspofungin for invasive pulmonary aspergillosis, and also the first to document that immunosuppressive metabolites secreted by Aspergillus fumigatus could be detected in sera of patients with aspergillosis. With the help of collaborators at MDACC, Dr. Lewis and his team were able to demonstrate that one of the metabolites, gliotoxin, could suppress human cell-mediated immunity through apoptosis of antigen-presenting cells. Currently, Dr. Lewis’s laboratory is focusing on how inflammation in non-neutropenic patients with invasive molds affects drug activity and host responses in the lung. He is a frequent invited speaker on topics relating to infectious diseases and has presented at numerous symposia and meetings.
