In my lab we focus on research issues relating to clinical neuropsychology. We have two broad lines of research that we have pursued here. One pertains to neuropsychological aspects of multiple sclerosis (MS), with special emphasis on contributors to depression in this common neurological disorder. In recent years we have also focused on the possible contribution of secondary factors like slow speech and poor visual acuity to neuropsychological test performance in these patients. Additionally, we will soon be exploring structural and functional neuroimaging indices associated with cognitive and affective functioning in MS.

We also study the consequences of sports-related concussion. My students and I run the sports concussion program for Penn State, something that involves neuropsychological testing of many of the athletes at Penn State involved in contact sports. We are especially interested in motivational factors that may influence testing, as well as how test indices such as variability can reflect either motivational factors or post-concussion symptoms depending on the testing context.

Both of these research programs provide students with the opportunity to develop their clinical skills and experience with two very different clinical populations, while at the same time exploring research questions that have both theoretical and applied implications.
