About

Biography

I’m an epidemiologist with applied research interests in pediatric cardiology, nutrition, and the impact of the developing infant intestinal microbiome on growth and early development. My areas of methodical research interest include applying and developing analytical methods for microbial metagenomic next-generation sequence data, dietary assessment and analysis methodology, predictive modeling and causal inference.

My interest in research stems from a desire to improve the health outcomes of children. I strive for the thoughtful application of epidemiologic research methods and biostatistics to support evidence-based care.

I collaborate broadly as a quantitative methodologist in health sciences research and lead the Biostatistics, Epidemiology and Research Design (BERD) Core of the Center for Clinical & Translational Science & Training (CCTST), the Microbial Metagenomics Analysis Center, and the Biostatistics Service for the Heart Institute Research Core at Cincinnati Children’s. My current work is largely focused on supporting these core services.

I have been a researcher for over 15 years and began working at Cincinnati Children’s in 2014.
