About

Biography

My research focuses on predictive modeling, longitudinal data analysis, environmental health, biomarker discovery and medical monitoring, with an emphasis on lung diseases and disorders. My lab designs and analyzes medical monitoring studies and integrates geo‑ and bio‑markers to improve early detection and prediction of rapid disease progression. Notable contributions include identifying pediatric phenotypes of rapid lung disease progression using the U.S. Cystic Fibrosis Registry and developing geo‑ and bio‑marker–informed prediction models.

I have taught introductory statistics and longitudinal data analysis and have developed advanced statistical and epidemiologic courses at the University of Cincinnati. I have nearly 20 years of experience in biostatistics, beginning my career at Cincinnati Children’s in 2007, and I have received recognition for biostatistical contributions to rare lung disease research. My work has been supported by the NIH, Cystic Fibrosis Foundation and The LAM Foundation.
