Research & Publications
Dr. He received the NIH Pathway to Independent (K99/R00) Award from the NIH/NIDDK. This award facilitated the transition of his career from postdoctoral researcher to an independent principal investigator.
Currently, he has two projects supported by NIH/NIDDK fundings: 1) to sudy the mechcanism of metformin action and AMPK's role in regulating glucose metabolsim in the liver; 2) to investigate the changes of intestinal microbiota composition and co-activater P300's role in the development of fatty liver.
