Kenneth Tran, MD
Clinical Assistant Professor, Surgery - Vascular Surgery
BioDr. Tran is a fellowship-trained 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).

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. -
