Paul A. Khavari, MD, PhD
Carl J. Herzog Professor of Dermatology in the School of Medicine
Current Research and Scholarly InterestsWe work in epithelial tissue as a model system to study stem cell biology, cancer and new molecular therapeutics. Epithelia cover external and internal body surfaces and undergo constant self-renewal while responding to diverse environmental stimuli. Epithelial homeostasis precisely balances stem cell-sustained proliferation and differentiation-associated cell death, a balance which is lost in many human diseases, including cancer, 90% of which arise in epithelial tissues.

Current Research and Scholarly InterestsResearch in this laboratory focuses on problems where deep insights into enzymology and metabolism can be harnessed to improve human health.
For the past two decades, we have studied and engineered enzymatic assembly lines called polyketide synthases that catalyze the biosynthesis of structurally complex and medicinally fascinating antibiotics in bacteria. An example of such an assembly line is found in the erythromycin biosynthetic pathway. Our current focus is on understanding the structure and mechanism of this polyketide synthase. At the same time, we are developing methods to decode the vast and growing number of orphan polyketide assembly lines in the sequence databases.
For more than a decade, we have also investigated the pathogenesis of celiac disease, an autoimmune disorder of the small intestine, with the goal of discovering therapies and related management tools for this widespread but overlooked disease. Ongoing efforts focus on understanding the pivotal role of transglutaminase 2 in triggering the inflammatory response to dietary gluten in the celiac intestine. -
Peter S. Kim
Virginia and D. K. Ludwig Professor of Biochemistry
On Partial Leave from 09/01/2023 To 06/30/2024Current Research and Scholarly InterestsWe are studying the mechanism of viral membrane fusion and its inhibition by drugs and antibodies. We use the HIV envelope protein (gp120/gp41) as a model system. Some of our studies are aimed at creating an HIV vaccine. We are also characterizing protein surfaces that are referred to as "non-druggable". These surfaces are defined empirically based on failure to identify small, drug-like molecules that bind to them with high affinity and specificity.

KM Mulberry Professor, Professor of Developmental Biology, of Medicine (Endocrinology) and, by courtesy, of Pediatrics (Endocrinology)
Current Research and Scholarly InterestsWe study the development of pancreatic islet cells using molecular, embryologic and genetic methods in several model systems, including mice, pigs, human pancreas, embryonic stem cells, and Drosophila. Our work suggests that critical factors required for islet development are also needed to maintain essential functions of the mature islet. These approaches have informed efforts to generate replacement islets from renewable sources for diabetes.

Alaina Kipps
Clinical Professor, Pediatrics - Cardiology
BioDr. Kipps grew up in Santa Cruz, California and completed her medical degree at Harvard Medical School in 2003. After general pediatrics residency at Stanford, she completed pediatric cardiology fellowship at Boston Children’s Hospital from 2006 to 2009. Having concentrated her final year of fellowship on echocardiography, she came west to practice at University of California, San Francisco until 2012. She was recruited back to Stanford in 2012 to become the medical director for acute care cardiology and she remained active in the echocardiography laboratory until 2016. In 2014 she co-founded the PAC³ network with Nicolas Madsen and co-directs this today. Her academic focus is in clinical effectiveness and quality improvement science, and she completed her Masters of Science in Epidemiology at Harvard School of Public Health in 2016. Her other significant interest is in teaching; she co-directs the pediatric residency cardiology rotation at Stanford.

Varvara A. Kirchner
Associate Professor of Surgery (Abdominal Transplantation) and, by courtesy, of Pediatrics
BioDr. Kirchner completed her medical school, surgical residency and multi-organ transplant fellowship in adult and pediatric liver, pancreas, kidney transplantation and total pancreatectomy with islet auto-transplantation at the University of Minnesota. She underwent further training in living donor liver transplantation and hepatobiliary surgery at the Asan Medical Center, Seoul, South Korea. Her clinical practice involves living and deceased donor liver and kidney transplantation in adult and pediatric patients as well as total pancreatectomy with islet auto-transplantation for patients with chronic and acute recurrent pancreatitis. She currently serves as Surgical Director of the Islet Cell Auto-Transplant at Stanford Children’s and Associate Director of the Living Donor Liver Transplant Program at the Division of Abdominal Transplantation. Dr. Kirchner’s research focuses on the biology of aging, cellular and solid organ transplantation. Her specific interests are in auto-islet transplantation, iPSC-derived hepatocyte therapies and liver regeneration. Dr. Kirchner's research on the impact of donor age on generation of iPSC-derived hepatocyte-like cells is supported by the NIA K08 Faculty Development Award. She is an active member of the American Society of Transplant Surgeons and the International Liver Transplantation Society.

Jonathan D Klein
Marron and Mary Elizabeth Kendrick Professor of Pediatrics
BioMy research interests include preventive services, confidentiality, access to care, youth development, tobacco control, and the translation of research into clinical and public health practice and global child health policy. Current projects address engagement of clinical leaders in countries and communities in health care delivery improvement, accountability measurement, and advocacy for adolescent health, comprehensive sexuality education, and non-communicable disease prevention.
