Jae Mo Park, Ph.D.

Jae Mo Park, Ph.D.

Associate Professor I Email 

Dr. Park received all of his degrees in Electrical Engineering. His doctoral work at Stanford University was focused on technical developments of magnetic resonance imaging (MRI) and spectroscopic imaging (MRSI) with application to preclinical brain tumor metabolism. Following completion of his Ph.D. in 2012, he broadened his research into advanced biomedical imaging as a postdoctoral research fellow and a research associate in the Department of Radiology at Stanford School of Medicine. He moved to the Advanced Imaging Research Center at the UT Southwestern in 2016 as an Assistant Professor. He also joined the Department of Electrical and Computer Engineering at UT Dallas in 2017. He has been an Associate Professor of the Advanced Imaging Research Center, Department of Biomedical Engineering, and Department of Radiology at UT Southwestern since 2022 when he received his tenure.

Crystal E. Harrison, Ph.D.

Research Scientist I Email 

Dr. Harrison received her BS in Physics at the University of Texas at Austin in 2003. She later got her MS and PhD, both in Physics, from the University of Texas at Dallas studying the metabolism of pyruvate in cancer using hyperpolarized 13C spectroscopy and imaging. Dr. Harrison held two postdoctoral positions at UT Southwestern in the Advanced Imaging Research Center and Radiology. Her research interests include MR sequence programming, data reconstruction, and mathematical modeling. Dr. Harrison is the Regulatory Manger of Human Studies at the AIRC, the primary operator of the human hyperpolarizer, the SPINlab®, and a mom of three.

Jun Chen, Ph.D.

Postdoctoral Fellow I Email

Dr. Chen graduated with a BA in Biomedical Sciences from Imperial College London in 2011. Afterwards, she obtained her PhD from Department of Biochemistry of UT Southwestern in 2017 where she researched how TORC1 regulates nitrogenic cataplerotic metabolism in response to amino acid starvation. She is interested in developing new probes for assessing intermediary metabolism and exploring the pathophysiological metabolism using 13C/15N-labeled MR imaging and spectroscopy.

Kelley A. Derner, R.N.

Research Nurse & Coordinator I Email 

She received her BS in Psychology from Texas A&M University and in Nursing from Texas Woman's University. Kelley joined the lab in 2022 as a research nurse and coordinator. Prior to joining the lab, she worked for UT Southwestern Medical Center, including the AIRC human core.

Mai T. Huynh portrait

Mai Huynh, Ph.D.

Postdoctoral Fellow I Email 

Dr. Huynh received her PhD in Chemistry from the University of Texas at Dallas where she researched the interaction of bovine serum albumin coated-MWNTs and macrophages using SR-A knockout RAW 264.7 cells that were generated using CRISPR-Cas9 technology. She is interested in synthesizing and developing the 13C-labeled metabolic probes generated by dynamic nuclear polarization and parahydrogen induced polarization techniques that can be used as a tracer in in vivo metabolism study and MRI.
