    The Eye Knows: Using Ocular Biometrics to Diagnose PTSD, Anxiety, and Depression

    What if diagnosing PTSD, anxiety, and depression could be as objective as a blood test — done in 10 minutes on your phone? That's the vision behind Sensei, a company using AI and ocular biometrics to bring measurable, objective diagnostics to mental health. In this episode, host Deborah Westphal sits down with David Zakariaie, founder and CEO of Sensei, to talk about the science of the eye, a $2M technology problem solved with a commercial camera, and why fixing mental health starts with fixing measurement. Key Takeaways Mental health's biggest crisis isn't just a shortage of care — it's a measurement problem. Major depression, the most commonly diagnosed mental health condition in the U.S., is misdiagnosed approximately 65% of the time. PTSD, bipolar, and schizophrenia are misdiagnosed between 84–92% of the time.Sensei's diagnostic app shows patients a series of ocular stimuli for roughly 10.5 minutes, captures their eyes' responses via a standard smartphone camera, and outputs a binary diagnosis plus a severity score.The platform measures approximately 45 individual metrics across three categories: traditional ocular metrics (pupil size, blinks, saccades, gaze), iris dilator and sphincter dynamics (mapping sympathetic vs. parasympathetic nervous system activity), and heart rate and heart rate variability from facial video.Sensei is currently in Phase 3 clinical trials for a PTSD diagnostic, with an FDA submission planned for late 2025 and approval expected in 2027.About 16,000 people participated in pre-trial studies; the full dataset at submission is expected to reach approximately 30,000.The go-to-market strategy focuses on telehealth platform integration — partnering with companies like Spring Health, Talkspace, and BetterHelp to embed the diagnostic tool directly into existing care delivery workflows.Future expansion targets schizophrenia, bipolar disorder, and ADHD, with longer-term interest in neurodegenerative conditions like Alzheimer's and dementia.About David Zacharia David Zakariaie is the founder and CEO of Sensei, a mental health diagnostics company building the first FDA-regulatory-grade platform for diagnosing and monitoring PTSD, anxiety, and depression using AI-powered ocular biometrics. His path began at 15, when he attended Google I/O, received an early pair of Google Glass, and became fascinated with the scientific potential of the human eye. He left high school after 10th grade, taught himself to code, and launched the company in 2015.

    The Third Pillar: Why Sleep Apnea, Circadian Rhythms, and Cognitive Health Are More Connected Than You Think

    Are you trading your long-term brain health for late-night screen time? Dr. Paul Chung, physician and researcher at Northwestern University, joins host Deborah Westphal to reveal why sleep is far more than rest - and why ignoring it could cost you decades of cognitive health. Dr. Chung is an Assistant Professor at Northwestern University, a pulmonary and sleep medicine physician, and a 2023 Toffler Scholar. His research sits at the intersection of sleep, circadian biology, and Alzheimer's disease - with a special focus on adults with Down syndrome as a model for understanding cognitive decline. What You'll Learn in This Episode Why sleep is an active process of repair - not passive rest - and how it regulates your heart, brain, immune system, and metabolismWhat sleep apnea actually is (beyond snoring) and why it causes a body-wide stress response every single nightWhy sleep apnea remains dramatically underdiagnosed - even 60 years after being formally defined - and what patients say when asked why they skip sleep studiesThe shocking truth: a third of adults and children still aren't getting enough sleep, and the number is even worse for teenagersHow disrupted circadian rhythms are linked to the buildup of amyloid beta - the protein central to Alzheimer's diseaseWhy individuals with Down syndrome are an invaluable research population for understanding Alzheimer's progression in the broader populationWhat "slow wave activity" in sleep EEG data reveals about cognitive declineThe science of chronotherapy - why when you take a medication or vaccine may be just as important as what you takeNight owls vs. early birds: the genetic reality behind your body clock, and why society quietly punishes night owlsThe future of personalized sleep medicine - beyond CPAPKey Takeaway Sleep is the third pillar of health alongside diet and exercise - yet it's the one most people sacrifice first About Dr. Paul Chung Dr. Paul Chung is a physician and Assistant Professor at Northwestern University's Feinberg School of Medicine, specializing in pulmonary and sleep medicine. He is a 2023 Toffler Scholar whose research focuses on sleep EEG microstructure, actigraphy, and circadian rhythms as they relate to cognitive vulnerability and Alzheimer's disease - with a particular emphasis on adults with Down syndrome.

    Why One Gene at a Time Isn't Enough: A Pioneer's View on Autism, Transcriptomics, and Future Cures

    What if the key to understanding autism isn't one gene — but thousands working together? In this episode of Research Renaissance, host Deborah Westphal sits down with Dr. Daniel Gershwind, Gordon and Virginia McDonald Distinguished Professor of Human Genetics, Neurology, and Psychiatry at UCLA, and Associate Vice Chancellor for Precision Health. A true pioneer in neurogenomics, Dr. Gershwind has spent over two decades reshaping how we understand autism and complex brain disorders — from building one of the first autism gene banks to applying transcriptomic network methods that revealed the molecular landscape of the brain in entirely new ways. This conversation is as much about the science as it is about how science gets done — through collaboration, curiosity, and a willingness to tackle the problems others walk away from. Key Takeaways Genetics doesn't mean "everything is genetic" — all human disease has both genetic and environmental components, but genetics offers a powerful, tractable starting point for understanding causeLooking at gene networks (rather than single genes) transformed the field by making sense of hundreds or thousands of genes at once — and revealing how biological systems adapt and respond to disruptionAutism affects approximately 1 in 100 children today — not because rates have risen, but because our ability to diagnose it has dramatically improved over the past 30 yearsAbout 15% of people with autism can now be identified with a specific causative genetic mutation through whole genome or exome sequencing — pointing toward targeted, precision therapiesTranscriptomics (measuring RNA expression across the brain) revealed shared molecular patterns in autism brains across different patients — a surprising convergence that has since been validated in large sample sizesAutism, schizophrenia, and bipolar disorder share some molecular pathology but are mostly molecularly distinct — a finding only visible at the transcriptomic levelCRISPR activation (without genome editing) has already been used in lab models to restore normal neuronal firing in certain autism-linked epilepsy syndromes — a proof of concept for future therapiesAI is now being used to connect gene networks to existing drugs, potentially accelerating drug discovery without needing full mechanistic understandingNeurodegeneration (including Alzheimer's and frontotemporal dementia) is closer to clinical trials than autism — but the two fields are informing each other in real timeAbout the Guest Dr. Daniel Gershwind is the Gordon and Virginia McDonald Distinguished Professor of Human Genetics, Neurology, and Psychiatry at UCLA. He leads the Gershwind Lab and serves as Associate Vice Chancellor for Precision Health. He co-founded the Autism Genetic Resource Exchange (AGRE), which became the leading data resource for autism genetics research for over a decade, and has been instrumental in developing transcriptomic network approaches now used widely across the field.

    The Brain's Plumbing Problem: A Neurologist-Scientist's Quest to Clear Alzheimer's Proteins

    What if one of the most promising frontiers in Alzheimer's research isn't just about what's building up in the brain - but how the brain clears it out? In this episode of Research Renaissance, host Deborah Westphal sits down with Dr. Tirth Patel, a neurologist and physician-scientist at UCLA and 2025 Toffler Scholar, to explore the cutting-edge science of brain clearance, tau protein, and the newly discovered lymphatic vessels surrounding the brain. This is a conversation about curiosity, persistence, and the kind of early-career science that could reshape how we understand and treat dementia. What You'll Learn in This Episode What tau protein is, why it "gunks up" the brain, and how it differs from amyloid beta in Alzheimer's diseaseThe recently discovered lymphatic vessels in the brain's meninges - and why they matter for clearing toxic proteinsHow sleep deprivation spikes tau and amyloid levels in the blood, and what that means for long-term brain healthThe glymphatic system: the brain's internal waste-clearance highway and its deep connection to sleepWhy aging slows down the brain's lymphatic drainage - and what researchers are doing about itThe genetics of Alzheimer's: the difference between causative mutations (APP, PS1, PS2) and risk factors like APOE4New FDA-approved blood tests and the promise of tau PET scans for better diagnosis and stagingThe latest treatments for Alzheimer's - how they work, their limitations, and what's coming nextWhy failure is one of the most undervalued tools in science - and what's missing in how the field handles negative dataA candid take on AI in biological research: where it helps, where it falls short, and whether it lets scientists failAbout Our Guest Dr. Tirth Patel is a neurologist and physician-scientist at UCLA, currently working in the lab of Dr. Jason Hinman. His research focuses on how the brain's meningeal lymphatic vessels clear tau protein from the brain to the bloodstream - a question with major implications for Alzheimer's disease and related dementias. Dr. Patel is a 2025 Toffler Scholar, supported by the Karen Toffler Charitable Trust. He is also the co-host of the podcast Recreational Science, where he and his colleague Dr. Lou Yang explore wacky but well-designed scientific studies to illuminate the scientific method. 📧 Reach Dr. Patel: tkpatel@mednet.ucla.edu Resources & Links Mentioned Karen Toffler Charitable TrustRecreational Science Podcast - co-hosted by Dr. Tirth Patel and Dr. Lou YangUCLA Department of NeurologyAlzheimer's Association resources on APOE4, tau, and amyloidLike what you heard?

    Rethinking Depression: Why Mental Health Is a Whole-Body Disease

    What if depression and anxiety are not just disorders of the brain, but conditions shaped by the entire body? In this episode of Research Renaissance, host Deborah Westphal speaks with Dr. Scott Russo, Director of the Brain Body Research Institute at Mount Sinai, about a major shift underway in mental health science. His work challenges the long-standing brain-only model of psychiatric illness and explores how inflammation, immune signaling, and organ systems interact with the brain to shape mood, resilience, and disease risk. From gut health to traumatic injury, this conversation reveals why mental health research is moving toward an integrative “systems biology” approach that could redefine treatment in the next decade. Key Takeaways Mental illnesses often coexist with medical conditions, suggesting they are whole-body disorders rather than isolated brain diseases.Chronic inflammation may be a shared biological driver across conditions ranging from depression to cardiovascular disease.Signals from peripheral organs can influence emotional states, meaning some emotions may originate in the body before being processed by the brain.Environmental exposures, infections, and life experiences may account for the majority of mental health risk, with genetics contributing a smaller portion.Emerging therapies may target immune pathways or body-brain signaling rather than neurotransmitters alone.Collaboration across disciplines is essential to advancing mental health research, yet institutional silos still limit innovation. About the Guest Dr. Scott Russo is Director of the Brain Body Research Institute at the Icahn School of Medicine at Mount Sinai. His work focuses on understanding how immune, metabolic, and neural systems interact to influence psychiatric disorders and resilience.

    Bioethics at the Bedside and Beyond: How Ethics Shaped Modern Medicine

    Modern medicine is not shaped by science alone. It is shaped by ethics, trust, and the difficult decisions made when technology moves faster than society can understand it. In this episode of Research Renaissance, legendary bioethicist Dr. Art Caplan reflects on a career that helped build the field of bioethics from the ground up. From surviving polio as a child to shaping national policies on organ transplantation, informed consent, and end-of-life care, Caplan offers a deeply personal and historically grounded perspective on how ethical thinking became essential to modern healthcare. The conversation explores the lingering distrust born from COVID-19, the ethical blind spots of artificial intelligence, the environmental cost of data infrastructure, and why communication between science and the public may be the most urgent challenge ahead. This episode is both a history lesson and a call to action. Ethics is not abstract philosophy. It is practical problem-solving for real people, real patients, and real consequences. Key Takeaways Bioethics emerged to solve real clinical dilemmas, not theoretical debates.Policies such as informed consent, brain-death standards, and organ allocation were shaped by early bioethics work.Public trust in medicine declined significantly after COVID-19 due to shifting scientific guidance and poor communication.AI introduces ethical risks beyond autonomy and bias, including environmental strain, privacy vulnerability, and unclear liability.The U.S. healthcare system’s structure, not just its technology, drives many ethical failures.Ethics must move from academic journals into communities through direct engagement and public dialogue.   Guest Spotlight Art Caplan, PhD One of the founders of modern bioethics, Dr. Caplan has advised governments, medical institutions, and research bodies on issues ranging from organ transplantation policy to emerging AI ethics. His work bridges philosophy, clinical medicine, and public engagement. Topics Discussed Origins of bioethics as a disciplineHuman subject protections and informed consentEnd-of-life decision frameworks and hospice careVaccine hesitancy and post-pandemic mistrustEthical governance of artificial intelligence in healthcareEnvironmental implications of digital infrastructureStructural inequities in U.S. healthcare deliveryThe role of communication in rebuilding scientific trustIf you found this conversation valuable: Follow Research Renaissance for more conversations at the intersection of science, policy, and human health.Share this episode with colleagues working in healthcare, research, or ethics.Leave a review to help more listeners engage with these critical discussions.To learn more about the breakthroughs discussed in this episode and to support ongoing research, visit our website at tofflertrust.org.
