As the most commonly used psychoactive substance worldwide, caffeine plays a central role in both daily life and health. While it’s most often consumed through coffee, its biological and societal impacts are remarkably complex—and increasingly relevant to both public health and product innovation.
This day-long convening of researchers, industry leaders, investors, students and more explores caffeine from multiple perspectives.
The morning begins with the UC Davis Coffee Center Annual Research Symposium, where faculty and graduate students will share cutting-edge research on roasting, extraction, defect detection, sensory science, and other innovations shaping the future of coffee.
In the afternoon, the IIFH Discovery Forum expands on the day’s conversation to explore caffeine’s bioactivity and emerging research, highlighting the potential for personalized approaches informed by chronobiology, genetic variability, and life-stage factors—within the evolving field of precision nutrition.
The UC Davis Coffee Center has provided ground-breaking research to the coffee industry. Currently, the Coffee Center is involved in coffee defect detection and computer vision machine learning AI, additionally, decaffeination sustainability, and partnering with the Middle Eastern and Southeast Asia studies for coffee culture education, history, and hands-on laboratory classes. Updates from previous work on coffee roasting research, refractive index, and published papers.
Following lunch, stroll over to the UC Davis Coffee Center for a self-guided tour of the space and treat yourself to an afternoon affogato.

Peter Giuliano | Executive Director, Coffee Science Foundation
Peter brings a human-centered lens to the evolving ways people think about caffeine. In a world where consumers increasingly seek balance, transparency, and personal agency, caffeine is no longer just a stimulant—it’s a choice woven into daily rituals, identity, and well-being. This talk will explore how cultural values, storytelling, and scientific understanding are reshaping preferences around caffeine—and what that means for coffee professionals, brands, and innovators alike.
A series of dynamic, short presentations from leading experts, followed by a moderated panel discussion with all presenters. This session explores the science behind caffeine’s physiological effects, how it’s metabolized, and how coffee processing influences caffeine content. We’ll also examine emerging technologies enabling more precise control of caffeine levels—from bean to body—and how this intersects with advances in biology, genetics, and precision nutrition.
