My areas of interest for research include pulmonary magnetic resonance imaging (MRI), hyperpolarized gas, rare lung diseases and pulmonary complications following bone marrow transplantation. My background and graduate school training are in hyperpolarized noble gas chemistry and physics. I have a desire to perform research that tells clinicians and researchers more about early lung disease, how lung disease changes over time and with treatment and has direct clinical benefit to individual patients.
The overarching goal of my lab is to develop and validate novel MRI techniques for visualizing and quantifying regional lung structure-function relationships in pediatric and adult lung diseases. With the use of techniques such as proton ultra-short echo-time (UTE) and hyperpolarized xenon-129 (129Xe) gas MRI, the pathophysiological mechanisms of rare lung diseases can be described. Because MRI is free of ionizing radiation, biomarkers from MRI are used to assess treatment response, especially in rare diseases with limited patient numbers. These findings can inform more individualized clinical care for patients, which could result in improved outcomes.
My research team was the first to demonstrate hyperpolarized 129Xe gas as a safe, inhaled contrast agent for lung MRI and show that 129Xe MRI was sensitive to early cystic-fibrosis lung disease. We also found that 129Xe MRI is feasible for use in children unable to perform spirometry, the clinical gold-standard test for lung disease.
I am a member of the American Thoracic Society, Alpha Chi Sigma, a co-ed professional chemistry fraterny and on the planning committee of the Assembly on Respiratory Structure and Function of the American Thoracic Society. I received the Scientific Abstract Award from the American Thoracic Society Assembly on Pediatrics in 2015 and the Rising Star Award from the American Thoracic Society Assembly on Respiratory Structure and Function in 2020.
