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. -
Brendan C. Visser, MD
Professor of Surgery (General Surgery)
Current Research and Scholarly InterestsDr. Visser's research interests span the breath of his clinical practice. Areas of active research include the multidisciplinary treatment of pancreatic neuroendocrine cancers, technical aspects of minimally invasive pancreatic and liver surgery, and trends in the management of hepatobiliary cancers in California, focusing on socioeconomic and instituional barriers to appropriate care.

Thomas G Weiser, MD, MPH
Clinical Professor, Surgery - General Surgery
BioDr. Thomas Weiser is a general, emergency, and trauma surgeon, and surgical intensivist. He treats and cares for injured patients and those with acute surgical emergencies as well as manages critically ill surgical patients in the Intensive Care Unit.
His research has focused on evaluating the role surgical care plays in the delivery of health services in resource poor settings, in particular low and middle income countries. He is interested in barriers to access and provision of surgical care, the quality of surgical services, and outcomes research as well as the science of implementation, how improvements can be made, and how to strengthen compliance with best practices and change behaviors for the better. He also has an interest in domestic policy as it relates to trauma outcomes, trauma systems, insurance coverage and costs of care, and firearm violence.
Dr. Weiser's efforts have led to improvements in the safety and reliability of surgical service, the quality of surgical care delivered globally, and improvements team dynamics, function, and communication. He works closely with Lifebox, a nonprofit focused on improving surgical and anesthetic safety worldwide, where he was previously the Consulting Medical Officer. Lifebox delivers programs throughout the world in combination with local partners and includes the procurement and distribution of low cost devices to improve the safety of care (including pulse oximeters for the routine monitoring of patients undergoing anesthesia and surgical headlights to safeguard care during power outage) and Clean Cut, a surgical infection prevention and control program that has reduced complications by up to 50%. This work safeguards millions of surgical patients every year.
From 2006-2009, he was part of the World Health Organization’s Safe Surgery Saves Lives program where he quantified the global volume of surgery and created, implemented, evaluated, and promoted the WHO Surgical Safety Checklist. He was part of the Lancet Commission on Global Surgery, the World Bank Disease Control Priorities Program, and a Gates Grand Challenge awardee.
From 2022-2026 he was the Program Director of Surgery: Assess/Validate/Expand (SAVE) at Wellcome Leap. His current research efforts aim to accelerate computer vision models for quantifying surgical performance and identifying mechanisms to predict patient recovery trajectories following surgery.
