Dr. Krishna Rao

Description of Research: Krishna Rao

Dr. Rao’s clinical and research interests include the diagnosis and management of healthcare-associated infections, especially Clostridium difficile infection. His clinical work includes managing the University of Michigan Fecal Microbiota Transplantation (stool transplant) program for recurrent Clostridium difficile infection, which he co-founded. He works with the Antimicrobial Subcommittee of the Pharmacy and Therapeutics Committee, where he provides expertise and support in the use of procalcitonin, a novel and promising biomarker for bacterial infections. He research includes infections in older adults and is supported by the Claude D. Pepper Older Americans Independence Center of the University of Michigan Institute of Gerontology.

His research is primarily conducted through the Enterics Research Investigative Network. His overall research aim is to investigate how biochemical, microbiological, and clinical factors can help decision-making in the treatment of healthcare-associated infections, and he hopes to ultimately integrate these factors into robust risk-prediction algorithms for use by clinicians.
