Kenneth Tran, MD
Clinical Assistant Professor, Surgery - Vascular Surgery
BioDr. Tran is a vascular surgeon in the Vascular and Endovascular Surgery Division at Stanford Health Care. He is also a clinical assistant professor in the Department of Surgery, Division of Vascular Surgery at Stanford University School of Medicine.
Dr. Tran’s clinical expertise includes the entire spectrum of vascular surgery, including minimally invasive strategies for aortic aneurysm repair and multiple methods of managing peripheral vascular disease. He also specializes in treating cerebrovascular disease (problems with blood flow in the brain) using carotid angioplasty and stenting, transcarotid artery revascularization, and conventional carotid surgery. In addition, Dr. Tran offers comprehensive dialysis access management and treats venous reflux (when leg veins fail to return blood to the heart).
Dr. Tran has a special interest in minimally invasive techniques for repairing complex aortic conditions using custom stents placed inside blood vessels (endografts). He has expertise in designing, fabricating, and implanting physician-modified endografts tailor-made to each patient’s unique aortic anatomy. This technique expands the ability to offer minimally invasive repair to more patients.
Dr. Tran’s research efforts focus on utilizing novel computational approaches to better understand and optimize blood flow patterns after complex aortic repair. This work has helped improve the understanding of how different types of aneurysm repair perform long term. Dr. Tran hopes to use these research findings to improve clinical outcomes for patients with aortic aneurysmal disease.
Dr. Tran has published his work in numerous prestigious peer-reviewed journals, including the Journal of Vascular Surgery, JAMA Surgery, and the European Journal of Vascular and Endovascular Surgery. He has presented at the podium at numerous national and international conferences.
Dr. Tran has received multiple research awards, including the Vascular and Endovascular Surgery Society’s Medtronic Resident Research Award and Best Resident Presentation at the Swiss Society for Vascular Diseases. In addition, he received the Young Researcher Prize at the European Symposium on Vascular Biomaterials for his research related to complex aortic repair hemodynamics (blood flow). Dr. Tran also coauthored a chapter in the book Complications in Endovascular Surgery. -
Amber Trickey, PhD
Casual - Non-Exempt, Stanford-Surgery Policy Improvement Research and Education Center
BioAmber W. Trickey, PhD, MS, CPH, is a health services biostatistician working with the S-SPIRE Center. She supports multidisciplinary teams in research design, implementation, and analysis. Dr. Trickey obtained degrees in epidemiology and biostatistics, and certifications in public health and SAS data analysis. She has evaluated data quality in surgical and trauma care, supported multiple clinical trials, and led data validation studies using the ACS-NSQIP surgical registry and administrative claims. Dr. Trickey has contributed to public and private grants on surgical safety, healthcare quality metrics, simulation-based training, team communication, error disclosure, and emergency services.

William J. Vasquez McTeigue
Life Science Research Professional 1, Surgery - Vascular Surgery
BioWilliam Vasquez McTeigue is conducting research in the lab of Katherine Hekman, MD, PhD, RPVI, FACS, where he applies induced pluripotent stem cells (iPSCs) to develop regenerative therapies for peripheral artery disease. His work bridges vascular surgery and stem-cell biology, with the goal of advancing treatments for patients with critical limb ischemia and other vascular disorders.
Beyond his current research, William is interested in cardiovascular innovation and translational medicine, aiming to pursue a career at the intersection of surgery, engineering, and regenerative biology. -
Jenny Lymary Veliz-Urzua, DNP, FNP-BC
Affiliate, Surgery - General Surgery
BioJenny L. Veliz-Urzua, DNP, FNP-BC is Nurse Practitioner for GI Surgical-Oncology at Stanford Health Care Center. She graduated with her Family Nurse Practitioner (FNP) degree from Yale University School of Nursing in 2006. Her area of clinical practice includes hepatobiliary, pancreas, gastrointestinal and peritoneal malignancies. She has worked closely with Dr. Byrne Lee, Program Director for Regional Cancer Therapies, to optimize HIPEC patient care experience.

Banita Verma
Postdoctoral Scholar, General and Vascular Surgery
BioI am Banita Verma, a postdoctoral researcher at Stanford University, currently working with Dr. Fredrick M. Dirbas at the Department of Surgery. Our research focus is to understand the type of cell death and the nature of immune responses triggered by FLASH versus conventional radiotherapy in various murine breast cancer models. Additionally, we aim to explore the role of DAMPs released by dying cells in generating immune responses after both FLASH and conventional radiotherapy. Furthermore, we are interested in studying the mechanism behind the low toxicity of the FLASH compared to conventional radiotherapy to the adjacent non-cancerous tissue. To accomplish this goal, our laboratory is actively collaborating with Dr. Bill Loo, who holds great expertise in the field of radiation oncology.
Before joining Stanford University, I served as a postdoctoral researcher at Karolinska Institutet, Sweden from 2021-2023. My research aimed to study the activation mechanism of Cholineacetyltransferase (ChAT), a pivotal enzyme in acetylcholine synthesis. This enzyme is known to be hypoactive in neurodegenerative conditions such as Alzheimer's and Parkinson's disease. Our group successfully synthesized novel compounds capable of enhancing ChAT activity.
I completed my doctoral research in cancer biology at the Department of Experimental Medicine and Biotechnology, PGIMER Chandigarh, India, in 2021. My work was the evaluation of role of TNF-α mediated Necroptosis in breast cancer cells. My primary research interests are cancer biology and cell death pathways. -
Joshua Aaron Villarreal
Affiliate, Department Funds
Resident in SurgeryBioDr. Villarreal is a current clinical informatics fellow at Stanford Medicine and first surgical resident to enter the program. He began general surgery training at Stanford in 2020. Dr. Villarreal is a Texas native and hometown is in McAllen TX. He completed medical school at Baylor College of Medicine in 2020 and undergraduate studies in Human Biology at the University of Texas.
During residency, Dr. Villarreal has published numerous articles in a wide range of surgical fields including: pediatric surgery, liver transplantation, trauma critical care and surgical data science. He currently holds the role as president of the resident led surgical research group Surgeon’s Writing About Trauma (SWAT) and mentors medical students and undergrads in conducting surgical related clinical research. He is a member of the Artificial Intelligence in Surgery research group at Stanford focused on leveraging methods in machine learning in the care of transplant patients.
His long-term goals are to apply clinical informatics frameworks to optimize surgical care workflows, enhance intraoperative decision making, and increase accessibility of outpatient surgical services to lower income patients. -
