Research description<\/h2>\n

Dr. Ambike studies movement in biological systems. He currently focuses on human prehension (manual behavior) and locomotion across the adult age span. He is interested in how aging influences stability of various movements, and how stability and maneuverability – two antagonistic movement attributes – are traded off in activities of daily living.\u00a0His current projects are (a) quantifying manual dexterity, (b) measuring and modeling mechanics at the fingertip-object interface, and (c) quantifying synergistic control of adaptive locomotion.\u00a0<\/p>\n\t
