Antonio Tomasso
Postdoctoral Scholar, Plastic and Reconstructive Surgery
BioAntonio Tomasso is an NWO Rubicon Postdoctoral Scholar. As part of his MSc in Medical Molecular and Cellular Biotechnology at Vita-Salute San Raffaele University, he explored the immunomodulatory and neurotrophic roles of neural stem cells (NSCs) following spinal cord injury. As a Research Assistant at Karolinska Institute, he delved into the signaling pathways required for NSC activation and migration after spinal cord injury, and the limited regenerative abilities of mouse and human heart.
During his PhD, he investigated the molecular mechanisms of tissue regeneration in planarians, axolotls and spiny mice. He conducted research as a Visiting Fellow at the University of Kentucky and the Hubrecht Institute.
His research demonstrated that MAPK/ERK signaling acts as a molecular switch between regeneration and fibrosis in adult mammals and can be activated to stimulate a regenerative response, including new hair follicle formation, in scarring wounds.
He contributed to a pioneering study showing that spiny mice can recover heart function after infarct through enhanced angiogenesis, ECM remodeling and epicardium regeneration. He also played a key role in spatial transcriptomic studies that defined regenerative and fibrotic gene signatures in spiny mice, laboratory mice and gerbils.
He earned a PhD cum laude in Molecular and Cellular Life Sciences at the Max Planck Institute for Molecular Biomedicine.
He has been awarded an NWO Dutch Research Council Rubicon Postdoctoral grant to conduct research on the molecular drivers of fibroblast activation in wound healing and organ fibrosis.
His ultimate research aim is to crack the code of tissue regeneration and rejuvenation, reversing organ scarring and preventing fibrosis in injuries and pathological conditions, through the identification of therapeutic targets for enhanced tissue repair and functional recovery.
Driven by his innate curiosity and passion for science, he loves tackling new challenges, thinking outside the box, and building interdisciplinary collaborations to push forward the boundaries of knowledge.
His career goal is to serve as a group leader, fostering a collaborative environment where everyone can thrive, achieve their goals and leave a lasting impact through community-building and scientific discoveries for the benefit of humankind. -
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).

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. -
