Research Interests
I am interested in the development of human coordination primarily from a neuromuscular perspective. This interest is satisfied by investigating locomotion and posture processes. More recent interests include the characterizing of gait and upper limb movements of individuals with genetic mutation developmental disorders, including those with NGLY1 deficiency, Rett Syndrome, Syngap1 deficiency, Phelen-McDermid deficiency, Rett Duplication Syndrome, and CDKL5 deficiency.
