My primary appointments are as a Research Investigator in the National Military Audiology and Speech Pathology Center at Walter Reed National Military Medical Center, Bethesda, MD. I also hold faculty affiliations as a Research Associate Professor in the Department of Surgery at the Uniformed Services University and as an Associate Research Scientist in the Department of Hearing and Speech Sciences at the University of Maryland. I completed my Ph.D. in Psychology at the University of Illinois and postdoctoral training in the Hearing Research Program at the Medical University of South Carolina. Using neuroimaging and pupillometry techniques, I investigate the sensory and attention systems that support language understanding in adverse conditions. A primary focus of my work aims to mitigate the speech-recognition challenges faced by older adults with hearing loss through interventions that optimize both comprehension accuracy and cognitive effort.
