Mytilee Vemuri
Clinical Associate Professor, Psychiatry and Behavioral Sciences
Current Research and Scholarly InterestsI am a Clinical Assistant Professor of Psychiatry, with clinical and research interests in hormonal influences on women’s mental and cognitive health. After Psychiatry residency I completed a NIMH research fellowship studying gender differences in metabolic complications such as dyslipidemia, obesity, and insulin-resistance in patients with bipolar disorder. As a research fellow, I also provided clinical oversight for research participants in studies evaluating hormonal change, metabolic biomarkers and mood. More recently, I have collaborated with PI Duncan and her research group on projects studying relationships between sex hormones and mood/anxiety disorders, particularly in peri-menopausal women. From these experiences I have gained experience in conducting clinical research and collaborating in interdisciplinary research teams. I have also had over 20 years of clinical experience as an attending psychiatrist in Stanford Women’s Wellness psychiatry, general psychiatry and primary care clinics treating a wide range of psychiatric conditions including perimenopausal and geriatric mood disorders. I have published review articles detailing the evidence-basis for treating mood disorders in women during times of hormonal change, and the role of hormones as potential treatments. I also serve as the Stanford Psychiatry Department’s clinical quality improvement leader, where I oversee multiple interdisciplinary improvement teams charged with improving the quality and efficiency of care processes. I currently specialize in managing perimenopausal mood disorders and have an interest in the judicious use of menopausal hormone therapy as an adjunctive treatment for mood symptoms in this population. My clinical and research experience in the intersection of women’s mental health, sex-steroid hormones, and the perimenopause, along with broad experience working on cross-disciplinary teams, will bring valuable input to this research team.

Abraham Verghese, MD, MACP
Linda R. Meier and Joan F. Lane Provostial Professor, Emeritus
Current Research and Scholarly InterestsMy interest is in clinical skills and the bedside exam, both in its technical aspects, but also in the importance of the ritual and what is conveyed by the physician's presence and technique at the bedside. This work interests me from an educational point of view, and also from the point of view of ethnographic studies related to rituals and how they transform the patient-physician relationship. Recently we have become interested in medical error as a result of oversights in the bedside exam.

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. -
