Dr. Wang has had many seminal research accomplishments throughout his career and published more than 150 peer-reviewed original research articles.  His research program has been continuously funded by multiple NIH grants, VA MERIT-Review awards, and VA Career Scientist Award over twenty-three years.  Dr. Wang’s service to the scientific community is exceptional, as he serves as a member of multiple NIH study sections and VA MERIT-Review study sections, and he is also on the editorial board for several scientific journals.  

Dr. Wang has successfully mentored young scientists and junior faculty.  Over the past ten years, >30 surgical residents, research fellows, graduate students, and junior faculty members have worked at Dr. Wang’s group; six trainees under Dr. Wang's mentorship received NIH grants (K01, R21, and R01), VA Career development Awards, and VA MERIT-Review Awards.

Research Interests

Dr. Wang's research is to define the roles and mechanisms of RNA-binding proteins (RBPs) and noncoding (nc) RNAs in gut mucosal regeneration, protection, and diseases.  His laboratory is particularly interested in the regulation of mRNA turnover and translation during mucosal growth, injury/repair, and epithelial barrier dysfunction.  Dr. Wang’s research program studies stress-related processes regulated by RBPs and ncRNAs, the post-translational events that affect target gene expression in the presence or absence of cellular polyamines, and the interplay between RBPs and ncRNAs in the gut epithelium homeostasis.  Dr. Wang’s group employs approaches that examine specific mRNAs as well as approaches focused on large-scale RNA analyses (microarray, RIP and ribosome profiling). His group has also used gain-of-function transgenic and tissue-specific knockout approaches to generate various genetically modified animal models.  The comprehensive approach and experience have provided him with an appreciation for the need to study mucosal tissue and cells directly, and to move back and forth from human disease to model systems and to validate key findings in the human context.  Importantly, Dr. Wang's research projects are directly relevant to surgical patients with massive mucosal injury/delayed healing, maladaptation, barrier dysfunction, systemic inflammation, and sepsis.
