"As a mother myself, I try to imagine how I could best help my kids get through some of our tests. I understand why parents ask a lot of questions while advocating for their kids."

My Biography & Research


For me, pediatric radiology is the perfect mix of technology, cutting-edge imaging, physics and problem-solving. Imaging is often used to narrow diagnoses and get answers about myriad symptoms. I enjoy helping solve these puzzles, especially for children who cannot clearly explain what they are feeling or experiencing. I have a degree in physics, so that side of imaging is also fascinating to me.

I practice pediatric radiology, especially ultrasound, and to a lesser degree nuclear medicine. As a mother myself, I try to imagine how I could best help my kids get through some of our tests. I understand why parents ask a lot of questions while advocating for their kids. We also monitor disease treatment and being able to see children grow and thrive as their health improves with therapy is very rewarding.

The Radiology Department at Cincinnati Children’s is truly amazing. Our doctors are brilliant, continually learning and conducting innovative research. As a team, we work closely with referring doctors and other Cincinnati Children’s physicians to provide expert care.

My research interests center on using ultrasound to answer clinical questions. I hope to replace more invasive tests or biopsies with gentler ultrasound scans.

I grew up in a small coastal town south of Boston and always loved walking along the beach in every season. The beach is still my favorite place to visit, even if only for a few minutes in my memories.
