Peter J. Niedbalski, Ph.D.

Professional Background

Dr. Peter Niedbalski is an Associate Professor at the University of Kansas Medical Center. During the course of his career, Dr. Niedbalski has transitioned from basic-science research in physical chemistry to translational magnetic resonance imaging (MRI).

Dr. Niedbalski received his Ph.D. in Physics from The University of Texas at Dallas, where he researched mechanisms of ¹³C dynamic nuclear polarization. From there, he completed a post-doctoral fellowship in the Center for Pulmonary Imaging Research at Cincinnati Children's Hospital Medical Center. During this post-doc, he developed new methods of quantifying lung structure and function using hyperpolarized ¹²⁹Xe MRI. Building on this work, he came to the University of Kansas Medical Center to begin a hyperpolarized ¹²⁹Xe MRI research program.

Research

Overview

I am a Research Assistant Professor in the Division of Pulmonary, Critical Care, and Sleep Medicine. My research is centered on pulmonary MRI using hyperpolarized ¹²⁹Xe. Xenon is an inert gas that can be made visible to MRI using a process known as hyperpolarization. Once hyperpolarized, xenon can be inhaled and imaged, providing images of regional pulmonary function. Specifically, ¹²⁹Xe MRI can be used to quantify ventilation, pulmonary microstructure dimensions, and pulmonary gas exchange non-invasively and with no ionizing radiation.

I am interested both in the development of new imaging methods and in using current methods for the characterization and monitoring of pulmonary disease. In particular, I am interested in developing imaging and analysis methods than can provide improved quantitative biomarkers of pulmonary function. These biomarkers can then be used to better understand the pathophysiology, progression, and treatment of diseases including asthma, hypersensitivity pneumonitis, idiopathic pulmonary fibrosis, cystic fibrosis, and many others.
