Researchers

Ariel Feldstein, MD is investigation the biochemical pathways of cell death triggers by over-accumulation of fatty acids and other lipids in the liver and other organs, which may play an important role in disease processes such as obesity-associated liver disease (nonalcoholic steatohepatitis or NASH), and type 2 diabetes.

Kimberly Newton, MD is primarily interested in the investigation of gut microflora and its relationship to celiac disease onset, in addition to the evaluation of potential biomarkers for monitoring celiac disease activity and dietary compliance. Read More

Paulina Ordonez, MD interested in using patient specific induced pluripotent stem cells (iPSC) to create models of disease. The Ordonez lab is currently exploring the underlying mechanisms and the contribution of these pathological phenotypes to the development of disease, and pursuing drug screening studies aimed at finding new therapies for NPC1 and related disorders. Read More

Jeffrey Schwimmer, MD is Director of the Weight and Wellness Center and Fatty Liver Disease Clinica and is researching the complications of obesity, both metabolic and behavioral; he is also working to identify genes and familial factors that determine susceptibility to fatty liver - the most common cause of chronic liver disease in children. Read More

Warren Shapiro, MD continues to be interested in functional GI disorders. He implemented a GI Biofeedback Clinic at Kaiser, which has had significant success in helping the difficult cases. He inaugurated a similar clinic at RCHSD. Read More
