Proprioception and kinesthesia
How people sense limb position and movement, and how that sense changes when muscle and tendon feedback is manipulated.
Research
Proprioception and movement control.
I study how people use sensory feedback to judge limb position, correct movement, and adapt when feedback changes.
Sensorimotor integration
How visual, tactile, and proprioceptive information contribute to goal-directed actions.
Motor learning and adaptation
How people adjust movements when feedback is altered, uncertain, or in conflict with intended action.
Neuromechanics and reflexes
How sensory pathways and muscle responses contribute to posture, balance, and movement control.
Research throughline
Sensory feedback under altered conditions.
I use tendon vibration, reaching and targeting tasks, reflex measures, and computational models to study what people do when sensory feedback becomes uncertain or misleading. Some of this work is methodological too: the experiments and analyses have to be built carefully before the physiology can be interpreted.
-
Tendon vibration studies test how altered muscle afferent signals bias perceived position and movement endpoint.
-
Kinesthetic targeting and discrimination tasks examine how the nervous system weights sensory information when feedback becomes noisy or ambiguous.
-
Bimanual and visual-proprioceptive tasks examine explicit and implicit components of sensorimotor adaptation.
-
Reflex and posture experiments connect sensory pathways with muscle responses during stance and movement.
