BioDr. Unaka is the inaugural Chief Health Equity Officer (CHEO) for Stanford Medicine Children’s Health (SMCH) and a Clinical Professor in the Department of Pediatrics at Stanford University School of Medicine. Prior to her transition to SMCH in July 2024, Dr. Unaka was a faculty member in the Division of Hospital Medicine at Cincinnati Children's Hospital. In addition to her clinical role as a pediatric hospitalist, Dr. Unaka served as the Associate Program Director of the Pediatric Residency Program from 2011 – January 2022. She served as the medical director of a 48- bed inpatient unit primarily for patients admitted to the Hospital Medicine service. In this role, Dr. Unaka was involved in several equity-oriented quality improvement initiatives which included work to identify, and address hunger among caregivers of hospitalized children insured by Medicaid.
Dr. Unaka worked on institution-level community health initiatives at Cincinnati Children’s. She served as the Medical Director of Quality Improvement and Data Analytics for Cincinnati Children’s Medicaid- focused, accountable care organization (HealthVine). In this role, she developed and led initiatives designed to improve the quality and efficiency of health care delivery to HealthVine’s patient population and helped lead the change management associated with the movement toward a population-health care model that improves quality, narrows equity gaps, streamlines care, and reduces costs. She helped define appropriate health care delivery, equity, and population health measures and quality benchmarks. Additionally, Dr. Unaka was a faculty lead within Cincinnati Children's Fisher Child Health Equity Center, and she specifically focused on working with operations leaders to ensure equity was embedded within all strategic plans, goals, and metrics across all sites of care. Dr. Unaka partnered with several colleagues to lead system-wide quality improvement initiatives including work accelerated via learning networks. She was the co-lead of Cincinnati Children's Health Equity Network (HEN), an initiative borne out of the pursuit of excellent and equitable health outcomes for youth in Greater Cincinnati. The HEN supports clinical teams seeking to eliminate disparities in child health outcomes by race, ethnicity, and/or socioeconomic status via targeted interventions and best practices by addressing both medical and social factors known to confer poor health outcomes. -

Sivakamasundari V
Instructor, Institute for Stem Cell Biology and Regenerative Medicine
BioMy research interests are focused on understanding the molecular basis of early development and stem cells, as it is often aberrations in stem cells or signaling mechanisms between tissues that lead to diseased states, including tumor development and cancer progression. Knowledge of stem cells and development is also critical to develop appropriate cell-based therapies for various diseases or injuries. My prior and current works take advantage of both traditional techniques (gene targeting, lineage tracing) and state-of-the-art technologies (Single cell RNA sequencing, Chromatin Immunoprecipitation (ChIP-seq), Imaging Mass Cytometry) to elucidate fundamental molecular mechanisms underlying signaling in tissue biology.

Nina Vasan, MD, MBA
Clinical Assistant Professor, Psychiatry and Behavioral Sciences
Current Research and Scholarly InterestsAt Brainstorm: The Stanford Lab for Mental Health Innovation, we lead the way in digital well-being: translating cutting-edge research into practical solutions for healthier tech use.
We are first and foremost practicing physicians; we treat patients and families. Then, grounded by the foundational oath in medicine to “do no harm,” we help companies build products that prioritize user health with responsibility and care. Our work has shaped platforms used by millions—helping Pinterest design "compassionate search", guiding TikTok in healthy screen-time management, and partnering with ML Commons to establish the first mental health safety benchmarks for large language models (LLMs).
Brainstorm is further committed to “do good” by leveraging these technologies to build a healthier digital world. We advised Dove’s Self-Esteem Project and Real Beauty Prompt Playbook, which studied AI’s impact on beauty and set new digital standards of representation. Additionally, after sharing the results of research conducted with the Stanford Center for AI Safety on the ethics, efficacy, and safety of LLMs providing mental health support, we developed the “Framework for Healthy AI” to guide industry best practices in AI product innovation.
As we apply this expertise to improve users' daily lives, it’s clear that addressing digital intimacy presents unique challenges compared to traditional human relationships. This technology is still emerging, and we are all adapting to it in real-time as it evolves. The big question is: How can we help users cultivate healthy, safe digital relationships?
After seeing success with the Stanford Social Media Safety Plan, which reduced harmful digital behaviors among users, we are now designing the Stanford GenAI Psychological Safety Plan (GPS). The Stanford GPS is a tool to help individuals, tech developers, and policymakers navigate this new terrain and make informed decisions about AI’s role in mental health.
Check out the start of the Stanford GPS in Fortune: This 4-question quiz from Stanford psychiatrists can help protect from the dangers of AI. -

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.
