Chenggang Liu
Research Assistant Professor

Chenggang Liu PhD. earned his doctorate at the University of Texas at Austin and has worked as a post-doctoral researcher on G protein signaling and miRNA biogenesis at the University of North Carolina and the Pennsylvania State University, respectively. In 2011, he joined Dr. Dixon's lab to study the proanthocyanidin biosynthesis pathway in Medicago and alfalfa. In 2013, he moved to the University of North Texas to work as a research assistant professor in Dr. Dixon's lab.
