Dr. Dua is a Clinical Assistant Professor of Surgery at Stanford.  She received her undergraduate degree from the University of California, Los Angeles and her medical degree from Drexel University in Philadelphia.  She completed her general surgery residency at Stanford University School of Medicine with a two year post-doctoral research fellowship in vascular biology.  She then went on to do a one year fellowship in minimally invasive and robotic surgery at the Cleveland Clinic and a second two year fellowship in hepatobiliary and pancreatic surgery back at Stanford University prior to joining the division faculty.  Dr. Dua is the associate program director for the HPB fellowship, an active instructor in the Stanford University surgical clerkship curriculum for medical students, and also serves as the regional HPB Surgeon at the VA Palo Alto Health Care System.

 

Dr. Dua participates in the Benign Pancreas Program at Stanford and her research includes both benign and malignant aspects of GI/HPB surgery with a focus on the management of severe pancreatitis as well as surgical strategies for the treatment of necrotizing pancreatitis.  Other research interests include the application of minimally invasive approaches to the surgical management of HPB diseases including laparoscopic techniques in liver surgery and the use of laparoscopic and robotic platforms in pancreatic surgery.


Jeffery A. Norton, MD
The Robert L. and Mary Ellenburg Professor of Surgery
Division Chief, General Surgery
Section Chief, Surgical Oncology

Dr. Norton was previously a Senior Investigator and Chief of the Surgical Metabolism Section at the National Cancer Institute.  He was Chief of Endocrine and Oncologic Surgery at Washington University in St. Louis.  He was Professor of Surgery and Chief of Surgery at the San Francisco VAMC at UCSF.  Dr. Norton is an expert on endocrine and upper gastrointestinal cancer.  He has published numerous papers on these diseases especially on the surgical management of gastric cancer and pancreatic endocrine tumors.  His laboratory effort is focused on improving the anti-tumor immune response through cellular immunotherapy with interleukin-12.  He received the Flance Karl Award from the American Surgical Association in 2012 for “achievements in translational research that have transformed the surgical approach to endocrine neoplasms.” He has several ongoing multi-department human clinical protocols for the treatment of pancreatic cancer and hereditary diffuse gastric cancer.  He is on the Editorial Board of Annals of Surgery, and Cancer Research.  He has published 374 papers in peer-reviewed journals.


George A. Poultsides, MD
Associate Professor of Surgery

Dr. Poultsides completed his medical degree at the University of Athens, School of Medicine in Greece and finished his general surgery residency at the University of Connecticut.  He did a two year surgical oncology fellowship through the Memorial Sloan-Kettering Cancer Center with a dedicated one year HPB track at John Hopkins University School of Medicine.

Dr. Poultsides serves as an assistant professor at Stanford University and achieved a Master’s Degree in Epidemiology at the Stanford University School of Medicine.  He is also the assistant program director of the HPB Fellowship Program and has been appointed as a member of the National Comprehensive Cancer Network clinical guidelines panel.

His research interests include collaborative efforts with the Stanford University Department of Chemistry to use mass spectrometric imaging to molecularly assess surgical resection margins for gastric and pancreatic cancer.  Dr. Poultsides has also been instrumental in the conception and execution of a multi-institutional registry of patients with gastric cancer who were treated surgically within seven US academic medical institutions: the US Gastric Cancer Collaborative. In addition, he has produced a considerable body of work characterizing the outcomes of operative management for patients with pancreatic neuroendocrine tumors.


Brendan C. Visser, MD
Associate Professor of Surgery
Medical Director, Cancer Center GI Clinical Care Program
HPB Fellowship Program Director

Dr. Visser received his medical degree from the University of California, San Francisco and stayed there to complete his general surgery residency.  He then went on to complete a hepatobiliary and pancreatic surgery fellowship at the University of Edinburgh in the United Kingdom. 

Dr. Visser is an associate professor at Stanford University and has been appointed the medical director of the Stanford GI Clinical Care Program.  He is the surgical director of the Stanford Healthcare Benign Pancreas Program as well as the surgical lead of the Hepatobiliary tumor board at both Stanford University and the VA Palo Alto Health Care System.  Dr. Visser is also the program director of the 2-year HPB surgical training fellowship which is accredited by The Fellowship Council and the AHPBA.  

He maintains an active clinical practice with research interests in the multidisciplinary treatment of hepatocellular carcinoma and trends in the management of HPB cancers with a particular focus on socioeconomic and institutional barriers to appropriate care and compliance.
