  • Professor, UC Department of Pediatrics



The research areas I am most interested in include clinical trials, predictive modeling, electronic health record data, meta-analysis, causal inference and missing data. My research lab's primary goal is to provide statistical assistance to researchers and investigators on study design and data analysis.

I’ve collaborated with investigators on traumatic brain injury, smoking, nutrition, cystic fibrosis, HIV, inflammatory bowel diseases, quality improvement, sleep intervention and medication, epilepsy, pain therapy, emergency department mediations, environmental health and attention-deficit/hyperactivity disorder (ADHD).

With my research team, I’m also designing novel statistical processes to manage issues arising from clinical and public health studies.

My love of math and statistics led me to my research interests. Over the years, I have become truly amazed how statistics can be used to solve real-world problems. One of the most promising discoveries my team and I made was published as Early Childhood Lead Exposure and Academic Achievement in the American Journal of Public Health. The findings in this paper were among the first to link lead exposure to academic achievement.

My 2019 article, Examination of Injury, Host, and Social-Environmental Moderators of Online Family Problem Solving Treatment Efficacy for Pediatric Traumatic Brain Injury Using an Individual Participant Data Meta-Analytic Approach, in the Journal of Neurotrauma was chosen as "Top publication" of the year in the Division of Biostatistics & Epidemiology. I am also proud of three awards won by my students/mentees.

I have more than 10 years’ experience in the biostatistics field and started working at the Cincinnati Children’s Hospital Medical Center in 2013. Other accomplishments I have include publishing more than 90 peer-reviewed articles and reviewing papers for more than 50 academic journals. My research has been published in journals such as Journal of the Royal Statistical Society, Biometrics, BMC Medical Research Methodology, Journal of Neurotrauma, Pediatrics and JAMA Pediatrics.
