Watch a video about my work

Dr. Erica S. Shenoy is an Associate Physician at the Massachusetts General Hospital where she specializes in the evaluation and management of infections among both hospitalized and ambulatory patients. Dr. Shenoy sees patients in the Infectious Diseases clinic at the Mass General Main Campus, and is available for follow up, initial consultations and second opinions.

Dr. Shenoy is Associate Chief of the Infection Control Unit. She is an Associate Professor of Medicine at Harvard Medical School and is trained as a health economist. Her research has evaluated the clinical, operational and economic impact of competing infection control strategies for methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) through clinical studies and mathematical modeling, has leveraged electronic health records for infection control surveillance, and applied machine-learning techniques to create risk prediction models for Clostridioides difficile infection. She has investigated and published on detection and prevention of nosocomial infections.

Dr. Shenoy is Medical Director of the Regional Emerging Special Pathogens Treatment Center at MGH, one of 10 facilities supported by the US Department of Health and Human Services as part of the regional treatment network for emerging pathogens. She has served as the Infectious Diseases and Infection Control advisor to MGH and MassGeneral Brigham for the COVID-19 response. She has published and lectured nationally and internationally on infection prevention and during the COVID-19 pandemic on approaches for SARS-CoV-2, the role of universal masking in healthcare settings and in the community, evaluation and management of healthcare workers infected with COVID-19, and on optimizing evaluation and isolation of patients with suspected and confirmed COVID-19 in healthcare settings.

Dr. Shenoy is a Fellow in both the Society for Healthcare Epidemiology of America (SHEA) and the Infectious Diseases Society of America (IDSA). She has served on the Guidelines Committee of SHEA and currently a member of SHEA’s Public Policy and Government Affairs Committee and co-chair of the Sterilization and High-Level Disinfection guidelines committee. An active member of IDSA, she previously served on the IDSA Antimicrobial Resistance Committee.

My research addresses the clinical, operational and economic impacts of competing Infection Control strategies for important nosocomial pathogens such as methicillin-resistant Staphylococcus aureus (MRSA). This involves hospital-based clinical studies, national survey-research, as well as “dry-bench” studies using computer-based simulation modeling. Our team collaborates with colleagues with expertise in computer science and articificial intelligence on risk prediction related to hospital acquired infections.  I also collaborate with colleagues on research and implementation of antibiotic allergy evaluations.
