Learning the hidden language of the human body

I study how physiology, behavior, environment, and time interact to understand human state and improve human alignment.

The Human Alignment Problem

Much of what determines how a human feels and performs is hidden from direct observation.

Human state emerges from interactions among physiology, behavior, environment, and time. These systems continuously generate signals that contain information about underlying state.

My research asks how we can read those signals, map the underlying space, and use that knowledge to guide action.

About Lara

Lara Weed, PhD, is a bioengineer and Wu Tsai Human Performance Alliance Postdoctoral Fellow in the Stanford Intelligent Systems Laboratory, where she is mentored by Prof. Mykel Kochenderfer. Her research combines human experiments, real-world sensing, and computational modeling to investigate hidden physiological state and develop personalized approaches to human health and performance. She completed her PhD in Bioengineering at Stanford with Dr. Jamie Zeitzer focused on human circadian and sleep regulation and building on earlier work in wearable biomechanics and physiological sensing.
