Past Visiting Scientists

Terry Ellis PT, PhD Boston ROC’s Visiting Scientist for 2013-2014

Dr. Ellis is an Assistant Professor at Boston University’s College of Health & Rehabilitation Sciences: Sargent College. As the Director of the Center for Neurorehabilitation at Boston University, she has several years of experience conducting clinical trials investigating the efficacy of particular types of exercise in persons with Parkinson’s Disease. During her tenure as Boston ROC Visiting Scientist, she has worked on building on her prior work in Parkinson Disease and lay the critical groundwork necessary to conduct a large-scale clinical trial examining the benefits of physical activity in slowing disability in persons with PD.

Beth Temple

Beth Pfeiffer PhD, OTR/L, BCP Boston ROC’s Visiting Scientist for 2012-2013

Dr. Pfeiffer earned a B.A. in Psychology and Special Education from Arcadia University; a M.S. in Occupational Therapy with a specialization in pediatrics from Temple University; and a Ph.D. in Occupational Therapy from Nova Southeastern University. She is an Associate Professor in the Department of Rehabilitation Sciences at Temple University teaching pediatric courses and mentoring research in the entry-level and post-professional occupational therapy programs. Her research focuses on sensory-based interventions and outcomes for children with Autism Spectrum Disorders (ASD). Dr. Pfeiffer’s interest in outcome measures research developed from a need to have valid and sensitive measures that can determine the effectiveness of interventions for individuals with ASD across the lifespan. Although there are many well-developed tools to guide in the treatment process for sensory-based disorders in individuals with ASD, there are few that are developed to measure the outcomes of interventions. Specifically, Dr. Pfeiffer is in the preliminary phase of developing an assessment measuring the impact of sensory processing in young children with ASD.

Jacob Kean

Jacob Kean, Ph.D., CCC-SLP Boston ROC’s Visiting Scientist for 2011-2012

Dr. Kean recieved his Ph.D. in Speech and Hearing Sciences from Indiana University, Bloomington, IN, in 2008; a  M.A. in Speech-Language Pathology from Indiana University, Bloomington, IN, 2002, and a B.S. in English Education from Ball State University, Muncie, IN, in 1996. His research interests include the assessment and treatment of acquired neurogenic cognitive and communicative disorders. He  currently directs projects to evaluate the impact of prescription medications on early cognitive recovery following traumatic brain injury and serves as a collaborator on several projects to refine measures of postacute rehabilitation outcome, telehealth compliance, and severe mental illness treatment fidelity. Dr. Kean was also invited to present  “Measuring early recovery and outcome following brain injury” at the HDRI seminar series in January, 2011.
