Juhun Lee, PhD

  • Assistant Professor, Department of Radiology, Imaging Research Laboratory

Dr. Juhun Lee received his PhD in Electrical and Computer Engineering at The University of Texas at Austin in 2014. Dr. Lee joined the Imaging Research Laboratory of the Department of Radiology in July of 2014 as a Postdoctoral Associate and was promoted to Research Instructor on February 1, 2017. His research focuses on breast imaging with an emphasis on using quantitative information extracted from breast computed tomography (CT) images, mammograms, and digital breast tomosynthesis to characterize breast lesions, estimate breast cancer risk,  and optimize image reconstruction. Dr. Lee has published 14 journal papers in the medical imaging field and two of them were honored as Editor’s Choice in Medical Physics. He has also presented over 20 presentations at national and international conferences. He recently received an R37 award from the NIH/NCI for his breast cancer risk estimation research. The R37 award allows an early stage investigator to have an opportunity for extending the research support for additional two years.
