I’m an epidemiologist with more than 40 years of experience in biomedical and public health research. Since 2011, I’ve served as director of the Division of Biostatistics and Epidemiology at Cincinnati Children’s, where I lead a cadre of 20 faculty and 60 professional staff comprised of talented epidemiologists, statisticians, project managers and clinical data managers whose expertise covers a vast array of methods and specific research areas.
Prior to joining Cincinnati Children’s, I was a professor of epidemiology at the University of Alabama at Birmingham (UAB). I also served as a distinguished consultant and branch chief at the Centers for Disease Control and Prevention (CDC). During my career I’ve taught epidemiological research methods to dozens of graduate students, research fellows, post-doctoral fellows and junior faculty members. I’ve also had the privilege of collaborating with clinical researchers, basic scientists and behavioral and social scientists representing academic institutions and government agencies on four continents.
Throughout my career in biomedical and public health research, I’ve passionately and rigorously applied the scientific method to the design and analysis of epidemiologic studies and clinical trials. My work has touched epidemiologic research methods, the design and evaluation of surveillance systems, cancer epidemiology, and occupational epidemiology, as well as reproductive health and infectious disease epidemiology.
I have provided leadership for the coordination and management of infrastructure and programs in support of clinical and translational research. I am a co-investigator at the Center for Clinical and Translational Science and Training (CCTST) at the University of Cincinnati College of Medicine and have served as associate director on its Executive Committee. In October 2019, The National Center for Advancing Translational Science (NCATS) awarded Cincinnati Children’s the Data Management and Coordinating Center (DMCC) for the Rare Diseases Clinic Research Network (RDCRN). As contact co-principal investigator of the DMCC, I help manage the shared resources and data from RDCRN research studies across more than 20 research consortia comprising more than 200 sites in the U.S. and across the globe. Our goal is to advance the methods and practice of rare disease research across the RDCRN and to the broader rare disease community. In July 2025, NCATS awarded a five-year renewal of the DMCC award, which extends the work of the DMCC through 2030.
As principal investigator or co-investigator on many research initiatives, I’ve helped secure more than $100 million in research funding from federal government agencies, non-profit organizations and industry. I have published more than 240 articles in respected journals such as JAMA, Epidemiology, The American Journal of Epidemiology, Toxicology, and the Scandinavian Journal of Work, and Environment and Health. My publications have been cited more than 9,000 times and my current h-index is 52. I’m also a fellow of the American College of Epidemiology.
