Mathangi Janakiraman
Postdoctoral Scholar, Gastroenterology
Current Research and Scholarly InterestsAs a postdoctoral scholar, I am studying the gut ecosystem, gut functionality nad neuroimmune interactions during aging and age-associated diseases like AD, and the role of fermented food in modulating gut health. I expect to be able to show that dietary modifications can help with healthy aging and to contribute to possibly leveraging dietary interventions therapeutically in age-associated diseases.

Kian Keyashian
Clinical Associate Professor, Medicine - Gastroenterology & Hepatology
BioThe management of inflammatory bowel disease continues to evolve, with the introduction of biologic and small molecule therapies and new goals of treatment, with an emphasis on healing the bowel. My career goal since my graduation from IBD fellowship in 2012 has been to improve the outcomes and quality of life of patients with inflammatory bowel disease. In line with these goals, my research has focused investigating new noninvasive diagnostic test, finding factors early in the disease course that might predict a more aggressive disease course and need for different therapies, and investigating new promising effective medications with less side effects.

BioI am clinically trained as a physician specializing in gastroenterology and hepatology. My research has focused on clinical research of nonalcoholic fatty liver disease (NAFLD) and obesity-related gastrointestinal diseases, focusing on a population-based study. In addition, my research was not only focused on gastroenterology and was expanded to cardiology, endocrinology, and neurology (sleep medicine). I have experience with large epidemiologic cohort studies as well as clinical trials. This work has resulted in over 250 published papers, including major journals such as Gastroenterology, Hepatology, Gut, Journal of Hepatology, American Journal of Gastroenterology, etc. (as the first and corresponding author). These publications have been cited more than 13,000 times.

W. Ray Kim
Professor of Medicine (Gastroenterology and Hepatology)
BioChronic liver disease is one of the most common causes of premature death in Americans. My career goal is to improve the outcome of individuals with chronic liver disease by identifying the optimal means for diagnosis, monitoring, treatment and prevention. The path I have chosen to achieve this goal is through engagement in clinical epidemiology and patient-oriented, effectiveness research.
Since the development of the MELD score which recognizes the importance of renal function in the prognosis of patients with end stage liver disease, one of the areas that we have had intense interest has been acute and chronic renal injury in patients undergoing liver transplantation. Liver transplantation represents a unique opportunity for research, because of the potential for reversal of the renal injury as well as access to biological materials. -

TZU HAN LO
Postdoctoral Scholar, Gastroenterology
BioTzu-Han Lo, a researcher at the Institute of Biomedical Sciences at Academia Sinica, has made contributions to the field of macrophage biology. His work has particularly focused on inflammation, especially in the context of fibrotic response. One of his works includes a study on the regulation of macrophage polarization in ureteral obstruction. This research has illuminated the role of inflammatory cell infiltration and activation during the early stages of kidney injury, a common pathological feature of chronic kidney disease.
In addition to his work on macrophage biology, Tzu-Han Lo has also delved into research related to galectins, a family of β-galactoside–binding proteins. His work in this area has centered on the role of galectins in recognizing microbial glycans, particularly lipopolysaccharides (LPSs). He has explored their impact on host defense mechanisms, including autophagy and both canonical and non-canonical inflammasome signaling pathways.
His research has offered insights into the complex interactions between host immunity and microbial components. This has contributed to our understanding of inflammatory responses and their implications for human health.
