Biography
Following his medical and doctoral studies, Dr. Williams completed a postdoctoral fellowship at the University of Pittsburgh under the tutelage of Dr. Andrew Schwartz. During this time, he initially studied the neural correlates of learning using intracortical BMIs as well as how to optimize training for new subjects naïve to BMI control. He later transitioned to advancing peripheral nerve optogenetic techniques to stimulate paralyzed muscle function. These techniques involve using virus injections to label nerves with light sensitive ion channels such that targeted muscles can be activated by exposing their nerves to specific colors of light. While optogenetic stimulation of muscle activity has many benefits over more traditional forms of electrical muscle stimulation, this approach faces a number of unique challenges including delivery and expression of desired gene products to target nerves, immune responses to light-sensitive ion channels that are not native to the body, and chronic means of light delivery to targeted nerves. These hurdles are critical issues that must be addressed before optogenetic stimulation technology may translated to clinical application for conditions such as spinal cord injury.
Dr. Williams joined the Biomedical Engineering and Neurosurgery Departments in August of 2019. His lab continues to develop neuroprosthetic devices, BMI technologies, and optogenetic therapies aimed at restoring motor function to spinal cord injury patients and other motor disorders. Collaborations with other members of the VA Neuroscience Labs also include using electrophysiology and optogenetic methods to study secondary injury phenomena that occur during the acute stages of spinal cord injury.
