Biography Hong Sun received his M.D. from Xuzhou Medical University in 1987. After served as a neurosurgeon for six years, he returned to graduated school in 1995 at Mie University School of Medicine. In 1999, he was granted a Ph.D. in neurosurgery. Following graduate school, he moved to University of Nebraska Medical Center and trained as a post-doc fellow (1999-2003) in the Department of Cellular & Integrative Physiology, and progressed through the ranks of Instructor (2003-2005) and Assistant Professor (2005-2011) before accepting a tenure-track Assistant Professor position in the Department of Cellular Biology & Anatomy at LSUHSC-Shreveport in 2011. He was promoted to Associate Professor in 2016.

Hong Sun has specific expertise in vascular biology and neuroscience. His research career has focused largely on developing novel strategies for the prevention and treatment of ischemic stroke. Alcohol is one of the most commonly used chemical substances. He has found that heavy alcohol consumption worsens, whereas light alcohol consumption reduces mortality and brain injury from ischemic stroke. His lab currently is investigating the mechanisms underlying the beneficial effect of light alcohol consumption and detrimental effect of heavy alcohol consumption on ischemic stroke. Obesity is another serious public health problem. The increased risk of ischemic stroke in obese individuals is also accompanied by a poorer prognosis after the ischemic insult. Blood-brain barrier (BBB) permeability and cerebral vasoreactivity are two important factors associated with brain injury following ischemic stroke. Another major direction of his lab is to investigate the influence of obesity on BBB disruption and cerebral vasoreactivity following ischemic stroke. His lab is currently supported by the National Institute of Health (NIH).

In addition to research, Hong Sun is extensively involved in teaching residents, graduate students and medical students and reviewing for the AHA and more than 20 scientific journals.
