Research & Publications

Research Summary

Dr. He’s research focuses on liver metabolism, in particular, glucose and lipid metabolism and the involvement of mitochondrial dynamics. Currently, his laboratory is working on an NIH-funded project to define the molecular mechanisms of metformin’s effects on mitochondrial dynamics and respiration through AMPK activation. He has another NIH-funded project to investigate mechanisms leading to the paradoxical concurrence of insulin resistance and hepatic steatosis in obesity and type 2 diabetes. In addition, his laboratory is studying the mechanisms responsible for the mitochondrial expansion in neonates.

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
