Chi Ma, PhD

Division of Radiation Physics

Dr. Ma was born and raised in China where he completed his undergraduate studies at University of Science and Technology of China majoring in Applied Physics. He received his PhD in medical physics from University of Wisconsin-Madison in 2014. During graduate school, he worked on the development of 3-dimensional ultrasound cardiac strain imaging techniques and analysis of envelope and radio frequency based elastography techniques. Dr. Ma completed his diagnostic physics residency at Mayo Clinic in 2016. He joined Rutgers Cancer Institute of New Jersey and Rutgers Robert Wood Johnson Medical School in 2017 as an instructor and was promoted to Assistant Professor in 2020. His current research interests lie in general radiological physics, Brachytherapy and imaging based clinical outcome study.
