Jesse Cook is a PhD candidate in the Dr. David Plante Sleep Research Laboratory and studies biological, psychological and sociological factors that connect with unexplained excessive sleepiness.
He was first drawn to Alzheimer’s disease (AD) research through the connection between sleep health and AD, and the prevention, detection and potential treatment implications of this connection.
Cook believes sleep health disparities across underrepresented groups may help explain disproportionate risk of AD. He is currently completing his dissertation and intends to pursue a career in behavioral sleep medicine as a clinical psychologist.______________________________________________________

🧠 Can AI and Wearables Transform Heart Function Research?From posture to activity levels, new AI-driven insights reveal how daily movements shape cardiovascular health.
In this episode, we explore how body position, physical activity, and AI-enhanced HRV data are revolutionizing heart function research. Wearable devices now track posture shifts—sitting, standing, lying down—and physical activity levels in real time, allowing researchers to analyze how these factors influence heart rate and autonomic function. Machine learning plays a key role by detecting patterns, predicting recovery trends, and identifying conditions like Postural Orthostatic Tachycardia Syndrome (POTS). Whether it's monitoring athletes' training adaptations or assessing the risks of prolonged sedentary behavior, AI-powered wearables provide continuous, real-world cardiovascular insights like never before.

📊 How Can We Capture Human Experience in Real Time?Traditional surveys rely on memory, but what if we could collect thoughts, emotions, and behaviors as they happen? That’s the power of the Experience Sampling Method (ESM).
In this episode, we dive into the Experience Sampling Method (ESM)—a research technique that captures momentary experiences, offering deeper insights into human behavior. Unlike retrospective surveys prone to memory bias, ESM gathers real-time data through smartphones, apps, and other digital tools. This method helps researchers understand daily life with unmatched accuracy, making it invaluable for psychology, healthcare, and behavioral science. We also explore different ESM approaches, from event-contingent to signal-contingent sampling, and discuss how technology is transforming its applications.

🚀 Supervised learning predicts outcomes, while unsupervised learning uncovers hidden trends—but what happens when we combine them?Machine learning is transforming physical activity research, but choosing the right approach can make all the difference.
This episode explores the differences between supervised and unsupervised learning in physical activity research, highlighting when to use each method and how they can be combined for more powerful analysis. Supervised learning excels at classifying activities and predicting health outcomes, while unsupervised learning reveals hidden patterns without predefined labels. We also discuss hybrid approaches like semi-supervised learning and reinforcement learning, which offer new possibilities for improving research accuracy and efficiency.
