I am looking for enthusiastic graduate students and post-doctoral fellows. If you are interested in the neural mechanisms of sensory perception and motor control, please email me a copy of your CV along with a brief description of your scientific interests and career goals.
Neural mechanisms underlying sensory perception and motor control
Motor behavior and sensory perception appear effortless but actually reflect a myriad of complex interactions between the mechanical properties of the body and a highly distributed neural circuit. The goal of my research is to explain how the nervous system handles and exploits these interactions when moving the arm and manipulating objects with the hands. Addressing this issue is essential to our basic understanding of sensorimotor function and may lead to better treatment following trauma (e.g. nerve and spinal cord injury) and disease (e.g. ALS) which often disrupt these interactions. In my lab, tackling this issue is a multi-disciplinary affair, including neurophysiological studies at various levels of the nervous system, targeted modeling efforts, behavioral and psychophysical studies, and patient work.
