Research

Mechanisms of locomotor function.

I study how muscle mechanics, gait mechanics, joint gear ratios, and vascular physiology influence locomotor function across healthy and clinical populations.

Projects

Research projects.

MS / Penn State

Plantarflexor architecture and Achilles tendon moment arm

My MS thesis examined how lateral and medial gastrocnemius architecture scales with ankle leverage in healthy adults.

PhD / Penn State

Calf stretching and joint gear ratio

My doctoral work studied daily calf stretching in peripheral artery disease and developed a device to isolate foot-ankle leverage effects in basic studies across healthy and clinical populations.

Postdoc / Utah

Limb asymmetries in blood flow and gait

Current work examines how limb-level gait mechanics and blood-flow regulation interact in people with unilateral transtibial amputation.

Highlighted work

Architecture and leverage.
