Dr. Pisegna’s main research interest is the molecular pharmacology of hormones and receptors in the gastrointestinal tract. These research and clinical interests derive from research in the biochemistry and molecular physiology of neuroendocrine tumors as well as an understanding of the molecular interaction of peptide hormones and their receptors. His clinical efforts are currently focused on the management of gastric hypersecretory conditions, neuroendocrine tumors of the GI tract, and Zollinger Ellison Syndrome (ZES), medical conditions that derive from alterations in the expression of gastrointestinal hormones. Dr. Pisegna cloned the receptor for human cholecystokinin A (CCKA), the cholecystokinin B (CCKB or gastrin) receptor and the pituitary adenylate cyclase activating polypeptide (PACAP) receptor. He has previously demonstrated that PACAP is a potent stimulant of gastric acid secretion and is expressed on neurons innervating the stomach, on enterochromaffin-like cells (ECL) of the stomach expressing receptors for PACAP. Using mice lacking the PAC1 receptor, he has demonstrated that the mice develop a gastric acid hypersecretory condition resulting from hypergastrinemia. Recently his lab is focused on understanding the role of peptide hormones in the development of obesity, metabolic syndrome and NAFLD. Dr. Pisegna's research interests extend to understanding the molecular mechanisms involved in satiety and metabolic syndrome including the role of the gastrointestinal microbiome.

David Geffen School of Medicine at UCLADr. Sarnoff graduated with honors from Brown University with a concentration in human health and biology. Between college and medical school, she worked in Dr. Jeffrey Friedman’s lab at Rockefeller University, where she investigated genetic enhancer proteins for leptin hormone. She completed medical school at NYU Langone School of Medicine, where she was inducted into the Gold Humanism Honor Society as a student role model for compassionate medical care. At NYU, she worked under the mentorship of Dr. Martin Blaser, investigating connections between the gut microbiome and precancerous colon polyps that was featured on CBS News. Dr. Sarnoff completed her internal medicine residency and chief residency at UCLA, where her passion for teaching, communication, and innovation in medical education and patient care led her to receive multiple teaching and young investigator awards. Primed by her microbiome work and ignited by the complex patients she saw during her residency, her interest in the gut environment expanded to disorders of gut-brain interaction (DGBI).
After chief year, Dr. Sarnoff partnered with her closest mentor, Dr. Lin Chang, to create a physician-scientist training program for herself with the goal of developing a DGBI niche within primary care. To learn how to design and critique clinical trials in the DGBI space, she is completing a master of science in clinical research, for which she has been granted Department of Medicine IGNITE funds. She is also a Career Enhancement Core scholar within the Chang-Mayer SCORE NIH grant, where she is designing her own studies as well as recruiting for clinical trials. Her research is also supported in part by the Goodman-Luskin Microbiome Center. She has been awarded support for the rest of her clinical and research training by the Department of Medicine. Clinically, she practices as a primary care provider at Internal Medicine Suites, where she trains residents and medical students. Finally, she trains under DGBI specialists such as Dr. Chang as well as the Integrative GI interdisciplinary care team. She is most interested in identifying factors that influence risk of developing DGBI, such as early life adversity, psychological comorbidity, and microbiome changes.
Dr. Sarnoff is board certified in internal medicine. She is dual appointed by the divisions of general internal medicine and digestive diseases.

Dr. Sternini's research program is focused on two major areas: 1) the neuronal circuits that form the enteric nervous system or “brain in the gut,” which regulate intestinal functions, and 2) chemosensing in the gastrointestinal tract in conditions of gut microbial imbalance and obesity. Studies on the enteric nervous system are focused on the identification of enteric neuronal circuits and their targets in health and disease states and on the mechanisms that govern receptor-mediated responses with an emphasis on the µ opioid receptors, the primary targets of opioids clinically used for pain control. Chronic use of opioids induces opioid bowel dysfunction, a debilitating condition characterized by severe constipation and abdominal pain, the treatment of which remains a major challenge. The discovery that opioids differ in their efficiency to induce receptor internalization, a key regulatory process of receptor function, in enteric neurons and that receptor trafficking and signaling pathways differ in distinct neuronal cell populations, sheds light on the mechanisms of action of opioids on enteric neurons compared to the brain, which is essential for the development of effective analgesics devoid of gastrointestinal side effects. Additional studies are focused on changes in the expression of transmitters and receptors in different pathological conditions such as intestinal ischemia, enteric neuropathies, and chronic constipation. Studies on gut chemosensing are focused on the expression and regulation of taste receptors in the gastrointestinal tract in diet-induced obesity based on the finding that bitter taste receptors, the first point of contact with foodstuff in the oral cavity that can impact on food consumption, are expressed in enteroendocrine cells in the intestine, and are upregulated in a microbiota-and diet-dependent manner. These studies are testing the innovative hypothesis that bitter taste receptors detect luminal content including bacteria and bacteria products to induce functional responses through the release of signaling molecules by enteroendocrine cells, which modulate intestinal homeostasis, caloric intake, and metabolism. Taste receptors in the gut might represent a functional link between microbiota and host leading to modulation of gut function, appetite and satiety through the brain-gut-microbiome axis and might be a potential target for obesity prevention and treatment.

Weiss was a member of the U.S. National Committee to the International Union of Pure and Applied Chemistry (2000-05). He has been the technical co-chair of the Foundations of Nanoscience Meetings and thematic chair of the Spring 2009 and Fall 2018 ACS National Meetings. He was the senior editor of IEEE Electron Device Letters for molecular and organic electronics (2005-07), and was the founding editor-in-chief of ACS Nano (2007-2021). At ACS Nano, he won the Association of American Publishers, Professional Scholarly Publishing PROSE Award for 2008, Best New Journal in Science, Technology, and Medicine, and ISI’s Rising Star Award a record ten times.

UCLADr. Yang's lab specializes in developing computational tools to integrate multiomics data (genetic, transcriptome, epigenome, proteome, metabolome, and microbiome) and model multitissue multiomics networks underlying complex diseases. She received her PhD in molecular genetics and bioinformatics from Georgia State University and then did postdoctoral training in systems genetics at UCLA. She was subsequently senior research scientist at Rosetta Inpharmatics/Merck & Co and then principal scientist and director of Systems Biology at Sage Bionetworks, before returning to UCLA as a faculty. Her experiences in both industry and academia enable a broad research portfolio from computational tool development and disease mechanism investigations to drug discovery and environmental exposure studies using multiomics approaches.
