Meet Our Residents

	Name and Background
	Elizabeth Polsdofer, PhD Medical Physics Resident, Third Year Education: PhD, Biomedical Engineering - Medical Physics, University of Texas Southwestern Medical Center MS, Medical Physics, Oregon Health Science University Research Area: Quality Improvement, Mathematical Oncology Biography: Elizabeth enjoys the multidisciplinary aspect of medical physics. For her doctoral research, she performed research in a molecular radiation biology laboratory where she learned tissue culture and how to conduct animal studies. These techniques became the cornerstone of her dissertation and allowed her to better understand how response to radiation is affected by the dose delivered and tumor biology. She joined the Department of Radiation Oncology as a medical physics resident in July 2023.

The design utilized an in-house ray tracing simulator to reconstruct refracted images through iterative reconstruction. He joined the Department of Radiation Oncology as a medical physics resident in July 2024.

His research studied the relationship between occupational exposures and lung diseases among U.S. workers. He has published over 35 peer-reviewed papers. He was also a member of the UIC MinER Center, working closely with pulmonologists and epidemiologists on the prevention of black lung disease among U.S. miners. He joined the Department of Radiation Oncology as a medical physics resident in July 2025.
