Academic Interests

Dr. Weber is the Chief Healthcare Epidemiologist and Medical Director of the Infection Control Program. His research interests focus on healthcare-associated infections, particularly those caused by multi-drug resistant organisms among hospitalized patients. With his research, Dr. Weber seeks to identify novel individual, population-based and institutional risk factors that influence the likelihood of these infections. In doing so, he collaborates with colleagues across the institution and at other centers to devise novel approaches to the prevention of infection. Dr. Weber’s research has led him to become engaged in issues regarding the practice of infection prevention in the wider community. In addition to playing an active role in infection prevention policy debates at both the state and federal level, Dr. Weber is a founding member of the Chicago Healthcare Epidemiology Roundtable, a consortium of local experts who promote transparency and innovation in infection prevention across the area.

Clinical Interests

Healthcare associated infections; Complicated infectious issues in the elderly.
