Current Projects

My current work is focused on the rehabilitation of bilingual aphasia. Based on a previously validated computational model that simulates language recovery after bilingual aphasia rehabilitation (Grasemann et al., 2011; Kiran et al., 2013; Miikkulainen et al., 2009), we are now examining the ability of the model to predict the optimal language of treatment for English-Spanish bilinguals with aphasia. We are also interested in testing the ability of the model to identify the factors that account for within- and across-language generalization. The ultimate goal of this project is to further our current understanding on how language recovery takes place in bilingual aphasia rehabilitation and to inform currently available treatments on the best language to target in rehabilitation and how to maximize cross-language generalization outcomes.
