Digital gait biomarkers for early detection of cognitive impairment.
Alzheimer’s disease and related dementias pose an immediate and growing threat to the health and quality of life for millions of older adults. Interventions for delaying onset are improved with early detection and digital biomarkers based on gait are emerging as key indicators. We have projects investigating the effects of cognition on motor control towards the development of new digital biomarkers of cognitive impairment.
Prevention and rehabilitation of musculoskeletal injuries.
In particular, hamstring and ACL injuries. We have projects investigating mechanisms of injury, assistive devices for rehabilitation and prevention of hamstring injuries; the relationship between pain, gait, and recovery; and the utility of remote gait analysis for improving rehabilitation outcomes.

Sparse-sensor human movement analysis.
We leverage wearable sensing and remote monitoring in almost every project. Practical deployment of these tools requires imposing a minimal burden to the user and, consequently, minimal sensor sets. That is, sparse sensing: we don’t have all the information we’d like to compute the variables of interest. We are investigating solutions at the intersection of machine learning and biomechanical modeling and simulation.
