My Biography & Research


My research interests involve developing testing methods for infectious diseases via clinical research trials. The type of goals my colleagues and I are attempting to reach through our research is to reduce the time it takes to detect infectious diseases as well as improve the sensitivity and specificity of diagnostic testing by applying cutting-edge technologies.

The patient care I specialize in involves diagnostic testing for infectious diseases. I was inspired to become a healthcare provider and work with children through a deep personal identification with this particular mission.

I have provided direction to the diagnostic laboratory to ensure the highest quality of results for our patients and I have provided consultation services to the healthcare staff in clinical microbiology. I’ve pursued expanding rapid testing approaches in a clinical microbiology laboratory and in outpatient settings.

I have more than 30 years of clinical microbiology experience and first joined the team at Cincinnati Children’s in 1991. In collaboration with faculty and fellows at Cincinnati Children’s Hospital, I have participated in more than 100 peer-reviewed publications, text chapters and case studies. Our research has been published in numerous respected journals, such as Diagnostic Microbiology and Infectious Disease, Journal of Clinical Microbiology, The Pediatric Infectious Disease Journal, and Pediatric Quality and Safety.
