Meet Our Residents

	Name and Background
Image	Andy Ogilvy, PhD Medical Physics Resident, Third year Education: PhD, Medical Physics, University of British Columbia, Canada MSc, Medical Physics, University of British Columbia, Canada BSc, Physics, University of British Columbia, Canada Research Area: 3D Dosimetry, Optical CT, Ray Tracing Simulation Biography: Andy completed a PhD in Medical Physics, designing and creating an optical CT scanner for use on 3D dosimeters. 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.
	Mason Ross, PhD Medical Physics Resident, First Year Education: PhD, Biomedical Physics, East Carolina University MS, Medical Physics, East Carolina University MA, Mathematics, East Carolina University BS, Applied Physics, University of Louisville Research Area: Monte Carlo Transport Modeling, Phantom Development Biography: Mason’s PhD research focused on computationally modeling the fluid properties of the quark-gluon plasma and investigating the baryon and electric charge stopping in relativistic heavy ion collisions. He has also collaborated in designing a phantom for determining the mechanical isocenter of a linear accelerator using pervasive clinical materials. Mason joined the Department of Radiation Oncology as a medical physics resident in July 2026.
