Carolee J. Winstein, PhD, PT, FAPTA

Dr. Winstein runs an interdisciplinary research program focused on understanding control, rehabilitation and recovery of goal-directed movements that emerge from a dynamic brainbehavior system in brain-damaged conditions. With NIH funding, she and her team are leading a multi-site phase III randomized controlled trial—ICARE (Interdisciplinary Comprehensive Arm Recovery Evaluation) stroke initiative--to improve outpatient therapy for arm paresis after stroke. With funding from the Foundation for Physical Therapy, she led the first Physical Therapy Clinical Research Network, PTClinResNet that supported clinical research on the effectiveness of task-specific/muscle-specific training to enhance muscle performance and functional activities across four disability groups including adult spinal cord injury, children with cerebral palsy, adult stroke, and low back pain. In 2008, with NIDRR/DoE funding, she and her colleagues at USC and Rancho Los Amigos National Rehabilitation Hospital established a Rehabilitation Engineering Research Center (RERC) to study the challenges of growing older with and into disabilities and the positive effects that new technologies can have on independence, health and quality of life. Recently with funding from NICHD and in collaboration with colleagues at USC, Winstein launched a new development-of-concept trial, Optimizing Dosage of Rehabilitation after Stroke (DOSE) to ultimately determine prospectively the dose of therapy that maximizes the efficacy of treatment—determine the smallest effective dose for individual patients.

Lawrence W. Barsalou, PhD
Professor of Psychology, Emory University

Lawrence W. Barsalou, PhD

Lawrence Barsalou is Samuel Candler Dobbs Professor of Psychology at Emory University. He received a Bachelors degree in Psychology from the University of California, San Diego in 1977, and a Ph.D. in Psychology from Stanford University in 1981. Barsalou's research addresses the nature of human knowledge, and its roles in perception, memory, language, and thought. The current theme of his research is that the human conceptual system is grounded in the brain's modal systems. Barsalou's research has been funded primarily by the National Science Foundation.

Anna Borghi, PhD
Associate Professor of Psychology, University of Bologna

Dr. Borghi is also an associate researcher at the Laboratory of Autonomous Robotics and Artificial Life (LARAL), Institute of Cognitive Sciences and Technologies (ISTC), National Reserch Council (CNR), Rome. She obtained her PhD in Psychology with a dissertation on the role of perception and action in categorization. Dr. Borghi is currently the coordinator of an FP7 project ROSSI (Emergence of communication in Robots through Sensorimotor and Social Interaction). Dr. Borghi's main area of research is embodied cognition and the interaction between knowledge and perception and action. Her current interests focus on the relationships between object concepts and action, the role of affordances in categorization, the grounding of language in sensorimotor processes. She works using both experimental methods and computer simulations.

Karalyn Patterson, PhD

Karalyn Patterson is a senior research scientist at the MRC-CBU (Medical Research Council Cognition & Brain Sciences Unit) in Cambridge UK, a Fellow of the Academy of Medical Sciences, and a Fellow of Darwin College, Cambridge. Her educational background is in experimental psychology, with degrees from the Universities of Toronto (Canada), Michigan and California (USA) and Cambridge (UK). Her research on language and memory disorders includes cognitive testing of different patient groups, to obtain detailed patterns of processes that are impaired and those that are still relatively preserved, combined with structural and sometimes functional brain imaging to reveal malfunctioning brain regions.

Assistant Professor, Communication Sciences & Disorders University of Florida

Lisa A. Edmonds, PhD, CCC-SLP

Lisa Edmonds, CCC-SLP, PhD is an Assistant Professor in Communication Sciences and Disorders at the University of Florida. Her primary research interests relate to lexical retrieval across a variety of language contexts (from single words to discourse) and modalities (e.g., spoken and writing) in monolingual English speakers and bilingual Spanish-English speakers and in persons with aphasia/bilingual aphasia. She is particularly interested in developing theoretically motivated treatments for aphasia, particularly Verb Network Strengthening Treatment (VNeST), to increase efficiency and communicativeness of lexical retrieval in sentences and discourse in persons with aphasia/bilingual aphasia.

Patricia Gough, DPhil

Patricia Gough has just completed a DPhil with Prof. Kia Nobre and Dr. Joe Devlin at the University of Oxford U.K. Her DPhil work was on the role of the left inferior frontal gyrus in language processing. She used TMS, fMRI, and ERP to investigate the possibility of fractionating the inferior frontal gyrus into regions with varying involvement in semantic, phonological, and grammatical processing. She is currently working as a postdoc, with Dr. Kate Watkins at Oxford, on a project investigating developmental stuttering.

Sarah H. Creem-Regehr, PhD
Associate Professor, Department of Psychology, University of Utah

Sarah H. Creem-Regehr, PhD

My research program involves several focus areas in space and object perception that are tied together by a common perspective that studying action representations is essential for studying visual cognition. One line of research asks how to define the modularity of the visual system with respect to functionally separate but interactive visual processing streams for perception and action. My second line of research examines the neural and cognitive mechanisms involved in spatial transformations of the self and of the external world. Most recently, I have been using virtual environments to examine perception, action, and spatial cognition, and at the same time asking fundamental questions about how virtual environments are perceived. This work involves an active interdisciplinary collaboration with faculty and students in computer science. My approach is to use both cognitive and functional neuroimaging methods to obtain converging evidence for the processes defining visual cognition.
