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, scRNA-seq, 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.
