Lu Sun, Ph.D.

Lu Sun is an Assistant Professor in the Department of Molecular Biology at UT Southwestern Medical Center.  He obtained his bachelor’s degree in Biological Sciences from Tsinghua University and earned his Ph.D. in neuroscience from the Johns Hopkins University. As a graduate student in Dr. Alex Kolodkin’s laboratory, he discovered key molecular mechanisms that wire visual circuits (Sun et al., Science 2013; Riccomagno*, Sun* et al., Neuron 2014; Sun et al., Neuron 2015). As a postdoctoral fellow mentored by Dr. Ben Barres (1954-2017) at Stanford University, he focused on neuron-glia interactions and identified novel mechanisms that govern spatiotemporal specificity of central nervous system myelination (Sun et al., Cell 2018). In 2020, Lu Joined the faculty at UT Southwestern as an Assistant Professor in the Department of Molecular Biology.  Lu has been awarded with several fellowships including the Helen Hay Whitney Postdoctoral Fellowship, National Multiple Sclerosis Society Career Transition Award, and NIH Pathway to Independent Award (K99/R00). As an Assistant Professor, Lu received UT System Rising STARs Award, 2020 BBRF Young Investigator Award (NARSAD Award), and 2021 NIH Director's New Innovator Award. Lu is an Endowed Scholar in biomedical research.
