Zhongxu An is currently a Ph.D. candidate in Biomedical Engineering at the University of Texas Southwestern Medical Center and works as a research assistant in the Advanced Imaging Research Center under the guidance of Dr. Changho Choi. He is dedicated in in-vivo 1H Magnetic Resonance Spectroscopy and Spectroscopy Imaging research in human brain at 3T and 7T. He has developed novel sequences for in-vivo detection of challenging metabolites including 2-hydroxyglutarate in IDH-muated glioma and GABA in normal brain. Recently, he focuses on high resolution imaging of these metabolites using Echo Plnar Spectroscopic Imaging technique.
