Understanding how people move to design assistive technologies that work with them.
We combine experimental and computational approaches in biomechanics and motor control to understand how wearable robots affect movement. We strive to develop adaptive systems that respond to the values and lived experiences of the communities we work with.
Moving through everyday environments requires reconciling competing demands, such as conserving energy while moving quickly or crossing uneven terrain while staying balanced. We are building models that infer those priorities from measured movement§. We are relating these priorities to the coordination strategies that express them and studying how both change with aging and neurological gait conditions.

Mobility aids shape both how people move and how they perceive that movement, with responses changing over time. We are designing lower-limb exoskeleton control strategies that keep adapting as people's behavior changes, personalizing assistance to multiple objectives§ and considering perceptual outcomes alongside physical performance. Our work examines the tradeoffs among these objectives and what leads devices to be adopted rather than abandoned as people engage with technology over longer timescales.

Learning a new motor skill depends on interpreting cues from the body and environment, a process that well-designed feedback can accelerate. We are developing real-time biofeedback paradigms that guide people toward strategies suited to their own movement, rather than a single prescribed target§. We are investigating which signals meaningfully aid learning under which conditions and how skills learned with feedback can endure without it, supporting independence in clinical and community settings.

Supporting mobility with technology requires more than building a device. We need ways to understand people’s priorities in the context of their own bodies and everyday environments, represent those priorities in our design objectives, and evaluate to what extent technology actually supports them. This framework provides a structure for connecting these considerations across the research process. Although shown as stages, the process is iterative, with insights from each stage shaping the others.
Learning from people's own accounts of their mobility, in the context of their values and goals.
Representing insights as qualitative and quantitative data that can be systematically analyzed and used to develop testable models.
Connecting models of biomechanical, neural, and psychosocial processes to understand how they jointly shape human behavior.
Creating physical systems and interfaces whose form and function are informed by integrated models of behavior.
Developing personalized control strategies that adapt device behavior to each person as they move.
Evaluating effectiveness beyond the laboratory, in the context of people’s everyday lives.
Each of these stages represents an important area of inquiry and collaboration. While our published and ongoing work focuses primarily on Encode and Operationalize—inferring movement priorities from behavior and building control strategies that respond to them—fully realizing this vision will require expertise and collaboration across the entire framework.
