Max Kasun
Research Professional, Psychiatry and Behavioral Sciences
BioMax Kasun works in the Roberts Ethics Lab and Kim Ethics Lab at Stanford, which use empirical methods to help anticipate, clarify and resolve ethical issues in modern biomedical research. He has interests in empirical and normative thought dedicated to increasing scientific understanding and societal appreciation of the nature, internal experience, and prevalence of mental illness and well-being, as well as in moral philosophy (e.g. justice, action, capability, neo-Aristotelianism, and pragmatism), cognitive and affective sciences, and philosophy of mind (e.g. embodiment and personhood). He has co-authored scientific, peer-reviewed articles and other scholarly work investigating ethical issues in research (e.g. authentic voluntarism in informed consent), medical education, public health, and neuroscience. His most recent contributions to NIH-funded scientific work (National Center for Advancing Translational Sciences; PI: Dr. Jane Kim) have focused on investigating ethical issues encountered in the design, development, and clinical integration of artificial intelligence, e.g., how environmental and cognitive factors shape appraisals of AI tools, clinical judgments, trust, and health decision-making.
Max is a co-author of several chapters in APA's Study Guide to DSM-5-TR (2024) including the chapters on bipolar and related disorders and personality disorders (American Psychiatric Association). He has published work in and provided editorial support for the peer-reviewed journal Academic Medicine (Oxford University Press) and for two works on the subject of trauma and crisis and related interventions, including a reference guide for providing mental health care to victims of state atrocity (United Nations, Springer). Previously, he served on leadership teams for the Stanford Mental Health Technology and Innovation Hub and Neurodiversity Project.
Max is currently working to develop a new Special Initiative of the Chair on Mental Health Care for Unhoused and Justice-Involved Persons (see https://med.stanford.edu/psychiatry/special-initiatives/mhuj.html). The initiative aims to bring together a community of scholars, public stakeholders, and health care professionals to help advance more humane and participatory inquiry and health policy in service of a population that faces profound controversy, health stigma, and scientific neglect. The initiative aims to improve how science is communicated to the public and policy decision-makers and to develop more evidence-based, pragmatic, strengths-based, and trauma-informed approaches to mental health care for unhoused persons, including those who have experienced episodic or cyclical involvement in the criminal and civil justice systems. -
Makoto Kawai
Clinical Professor, Psychiatry and Behavioral Sciences - Sleep Medicine
BioI am a physician scientist in the field of sleep medicine in aging and brain function. Using combined polysomnogram and novel neuroimaging technology, I aim to identify potential sleep biomarkers to investigate the mechanism of progression from normal aging to Mild Cognitive Impairment (MCI) or dementia. I also investigate the impact of sleep on cognitive/affective function or behavior abnormality in various neurodevelopmental and neurodegenerative disorders.

Debra Lee Kaysen
Professor of Psychiatry and Behavioral Sciences (Public Mental Health and Population Sciences)
Current Research and Scholarly InterestsMuch of my current research focus is on the development of testing of accessible, scaleable, and effective treatments for trauma-related disorders and related comorbidities (e.g. substance use disorders, HIV, mood disorders). This work has focused on addressing trauma-related disorders especially in underserved populations and settings. This includes research in rural communities, with Native American communities, and with sexual minorities. My research has had a strong impact on building an evidence base on adaptations of psychotherapies for PTSD and substance use disorders for diverse populations both within and outside the United States. Our findings demonstrate that complex cognitive behavioral psychotherapies like Cognitive Processing Therapy can be culturally adapted and delivered in challenging settings (conflict settings, high poverty environments) with significant and lasting change in PTSD, depression, and functioning. This has led to work adapting CPT for diverse populations within the United States (rural Native Americans, urban Latinos) and outside of it (Iraq, DRC). Other research has focused on treatment for PTSD/SUD. My research has also found support for the use of brief telehealth interventions to build treatment engagement and to reduce drinking among trauma-exposed populations. In addition, my work has been critical in testing the feasibility of novel trauma-focused interventions for use by those with PTSD and SUD, thus paving the road for more rigorous research studies.
Current PI'ed research studies include: 1) developing and evaluating a brief motivational interviewing intervention designed to increase treatment-seeking among military personnel with untreated PTSD; a two-arm randomized comparative effectiveness trial to evaluate prevention of HIV/STI sexual risk behavior by addressing PTSD through Narrative Exposure Therapy or substance use through Motivational Interviewing among Native American men and women with PTSD; and 3) a comparison of outcomes among patients randomized to initially receive pharmacotherapy or Written Exposure Therapy delivered in primary care as well as comparing outcomes among patients randomized to treatment sequences (i.e., switching and augmenting) for patients who do not respond to the initial treatment. -
Corey Keller, MD, PhD
Associate Professor of Psychiatry and Behavioral Sciences (Public Mental Health and Population Sciences)
Current Research and Scholarly InterestsThe goal of my lab is to understand the fundamental principles of human brain plasticity and build trans-diagnostic real-time monitoring platforms for personalized neurotherapeutics.
We use an array of neuroscience methods to better understand the basic principles of how to create change in brain circuits. We use this knowledge to develop more effective treatment strategies for depression and other psychiatric disorders. -

Kevin Kelley
Assistant Professor of Psychiatry and Behavioral Sciences (General Psychiatry and Psychology)
BioAs a neuroscientist and psychiatrist, I am motivated by how little we understand about the pathophysiology of psychiatric disorders and hope that further knowledge will help to alleviate the ongoing distress of many of our patients. My research program leverages computational genomics, human brain cellular models, and molecular neuroscience techniques to understand the cellular and molecular mechanisms of human brain development and how dysfunction in these processes lead to psychiatric disorders.

Wayne Kepner
Postdoctoral Scholar, Psychiatry
BioWayne Kepner, PhD, MPH is a public health researcher whose work examines how addiction treatment systems can be organized to support long-term recovery. He is an Instructor in the Department of Psychiatry and Behavioral Sciences at Stanford University School of Medicine, where he holds a NIDA Mentored Research Scientist Development Award (K01DA067040) as principal investigator. The award funds a five-year study of how medications for opioid use disorder and mutual help groups fit together in addiction treatment, along with development of a user-centered intervention to bridge the two. Dr. Keith Humphreys serves as his primary mentor and Dr. Mark McGovern as co-mentor. Dr. Kepner joined the Stanford faculty in 2026 after completing the school's NIDA T32 postdoctoral fellowship in Pain and Substance Use.
Dr. Kepner received his doctoral degree from the Joint Doctoral Program in Interdisciplinary Research on Substance Use at San Diego State University and the University of California, San Diego, and he holds an MPH from San Diego State University. His doctoral research addressed substance use disorders, health services utilization, and geospatial analysis of health data, with particular attention to older adult populations. Across more than thirty peer-reviewed publications, he has studied the implementation of low-threshold opioid treatment, emergency department utilization for substance-related diagnoses, national trends in stimulant and cannabis use, and harm reduction for older adults in opioid treatment programs. He works in both qualitative and quantitative traditions, with interviews of people who use drugs alongside analyses of large electronic health record and national survey datasets. Journalists at the Washington Post, CNN, and Forbes have covered his research, and the Urban Institute cited his work on stigma in its analysis of Oregon's Measure 110.
Alongside his academic work, Dr. Kepner maintains an active commitment to recovery communities and community-based organizations. He co-founded Aztecs For Recovery, the collegiate recovery program at San Diego State University, and he now advises SMART Recovery USA and Narcotics Anonymous World Services on research. He also serves on the board of the Asian American Drug Abuse Program, where he advises the implementation of a $20 million state grant to expand behavioral health services for Asian American and Pacific Islander communities. -
