Dr. Katzman's research career has evolved significantly over time. For more than two decades, his work focused on the structure and function of retroviral integrase enzymes, particularly in HIV, avian sarcoma viruses, and visna virus. His contributions include the first purification of enzymatically active retroviral integrase from bacterial expression systems and the development of assays still used to study this enzyme today. More recently, his research has shifted to antimicrobial stewardship, with numerous publications on Clostridioides difficile infections, antibiotic treatment guidelines, and optimizing antimicrobial stewardship programs through electronic medical records.

His most recent publications demonstrate a clear trend toward clinical applications of infectious disease research, particularly in hospital epidemiology and antimicrobial stewardship. The 2023 article on reducing Clostridioides difficile infections represents the culmination of his work in infection control, while his 2019 paper on electronic medical record customization shows his adaptation to modern healthcare technology.

• Distinguished Educator Award (2011)

Dr. Katzman has secured multiple NIH-funded research projects throughout his career, including three significant grants from the National Institute of Allergy and Infectious Diseases. His 1991-1995 project focused on HIV-1 integration, followed by substrate interaction studies (2000-2002), and novel stimulators of HIV-1 integrase (2007-2010). As his career evolved, he transitioned from basic science research to clinical applications, establishing and directing Penn State's Antimicrobial Stewardship Program since 2011.

Dr. Katzman leads the Antimicrobial Stewardship Program at Penn State Health Milton S. Hershey Medical Center, which involves collaboration between infectious disease specialists, pharmacists, and clinical microbiologists. His work contributes to UN Sustainable Development Goals related to good health and well-being through his research on appropriate antimicrobial use and infection control.
