My Biography & Research


My interest in pediatric medicine began at a young age. I was quite ill as a child and became inspired by the physicians who cared for me.

During college, I realized I also enjoyed research. So, I decided to pursue a career that would combine research and patient care. I completed a fellowship in critical care and a PhD in microbiology and immunology.

Today, I work in the Pediatric Intensive Care Unit, where I continuously care for children who struggle to overcome sepsis. My research, which draws on my training in neutrophil biology, neutrophil heterogeneity and immunology in the critically ill, aims to understand why some kids quickly recover from sepsis while others do not.

I’ve received research funding from a variety of sources. This funding includes a K08 Mentored Clinical Scientist Development Award from the National Institute of General Medical Sciences and a Procter Scholar Award from Cincinnati Children’s.
