Dr. Clare Rock is an Assistant Professor of Medicine, Division of Infectious Diseases at the Johns Hopkins University School of Medicine, Associate Hospital Epidemiologist at the Johns Hopkins Hospital, and Faculty Member at Armstrong Institute for Patient Safety and Quality.

Dr. Rock's research expertise is healthcare environmental hygiene and mitigating the role that environmental transmission plays in acquisition of multidrug-resistant organisms. With CDC funding, she applies human factors, systems engineering and other novel approaches to enhance current hospital environmental hygiene practices. She speaks nationally and internationally on this and other infection prevention related topics. Dr. Rock co-leads the Maryland Statewide Prevention And Reduction of Clostridioides difficile (SPARC) collaborative, where she assesses and advises hospitals on environmental cleaning practices, and other C. difficile prevention strategies.  Her other area of interest is diagnostic stewardship, and the behavioral, cultural and human factors aspects of implementation of initiatives to enhance appropriate use of diagnostic tests. Dr. Rock is principal investigator of the Johns Hopkins 2018-2020 CDC Prevention Epicenter grant using innovative approaches to improve appropriate C. difficile testing. She is Chair of Society for Healthcare Epidemiology of America (SHEA) Research Network, served on SHEA research committee and is research director for High Value Practice Academic Alliance.
