Beth Temple

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

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.

Dr Resnik’s research activities bridge the methodologies of rehabilitation and health services research. Her interests include rehabilitation service delivery, outcomes measurement, prosthetics and amputation, and postdeployment reintegration. She is a member of 3 research teams; Brown’s Center for Gerontology and Health Care Research, Providence VA’s Research Enhancement Program and Center for Restorative and Regenerative Medicine. More….

Dr. Resnik’s work at the Boston ROC will focus on patient-reported outcomes. She is working to develop a new instrument to assess community reintegration among veterans.
