Her research interests include environmental transmission, with particular interest in CRE outbreak management, and the transmission and epidemiology of C. difficile. She also focuses on diagnostic stewardship, and the behavioral, cultural, and human factors aspects of implementation of initiatives to enhance appropriate use of diagnostic tests. Dr. Rock earned her MD at the University College Dublin School of Medicine, National University of Ireland, and her MS masters of clinical science of research at the University of Maryland, where she received the MS scholar award for epidemiology.

Marin Schweizer, PhD
SRN Review Committee Chair

Dr. Marin Schweizer is an Assistant Professor of Internal Medicine at the University of Iowa Carver College of Medicine and a core investigator at the Iowa City VA Health Care System Center for Innovation. She received her PhD in Epidemiology from the University of Maryland, Baltimore. Her research focuses on developing and evaluating evidence-based strategies to reduce the prevalence of and poor outcomes associated with healthcare-associated infections, including prevention and treatment of surgical site infections, and comparative effectiveness of medications to prevent and treat S. aureus bloodstream infections. She has expertise in study design, meta-analysis, and outcomes research.


The unique healthcare institutions that make up the SHEA Research Network (SRN) respond to 6-10 research projects every year. These projects are reviewed and approved by the SRN Review Committee for their potential contributions to the knowledge base of healthcare epidemiology.  

SRN Elite institutions have the highest response rate and are recognized for their exemplary contributions to the SRN.

The SHEA Research Network (SRN) is a consortium of over 100 hospitals collaborating on multi-center research projects of interest to the SHEA membership to identify important gaps in the healthcare epidemiology science base and address them by contributing data and expertise. 

All hospitals with a dedicated site PI are able to join the SRN and participate in future projects. Approval of proposed research projects is determined by the SRN Review Committee upon submission of a concept form.

Engaging the Network

Investigators interested in engaging the SRN for a study should review and complete the online Study Proposal Concept Form and submit it to

Proposals funded by an external source or those seeking funding from an external source will be reviewed for project significance and alignment with the mission and capabilities of the SRN. For unfunded proposals, consideration will also be given to the burden on participating sites. If the research proposal aligns with the mission and capabilities of the SRN, the concept sheet alone may be sufficient and will be approved by the SRN Application Review Committee. Review of proposals will not commence until all materials are received.

Fee Structure

  • Federally funded grants (excluding training or career development grants): $2,000
  • Corporate funded grants: $5,000
  • Fees cover review and solicitation of members; they do not cover administrative support and data management.
  • Proposals that require additional resources (e.g. Adelphi process with multiple rounds of surveying) will be assessed an additional fee to cover administration of the proposal. The amount will be determined following review of the proposal.
  • Proposals that are not accepted will not be charged.
  • Fees will not be assessed for unfunded research projects (i.e. conducted with no visible means of support).
