Curriculum Vitae of Marcia C. Linebarger

Overview:

My professional life has revolved around three disciplines: formal linguistics, the study of acquired language disorders, and the development of computer software. I completed a PhD in theoretical linguistics, received postdoctoral training in aphasiology, and spent several years exploring language processing in aphasia with Myrna Schwartz (Moss Rehabilitation Research Institute) and Eleanor Saffran (Temple University). I then entered the field of computational linguistics, spending 16 years in an industry setting (Unisys Corporation) with a research group developing natural language understanding software, which allows computers to process spoken human language. Ten years into this position, I was able to join these varied professional threads when I received an R01 grant from NIDCD to develop aphasia treatment software at Unisys and investigate its effects at MossRehab with my former colleagues. During this grant, I invented SentenceShaper, a communication aid for aphasia. Research studies with this aid were quite promising, and in 2001 I left Unisys and started my own small business, Psycholinguistic Technologies, Inc., which has released SentenceShaper as a commercial product. In subsequent NIH-funded collaborations between Psycholinguistic Technologies and MossRehab (Myrna Schwartz) and the University of Maryland (Rita Berndt, Denise McCall), we examined the impact of SentenceShaper as a communication aid and as a therapy tool. In recent years, I have focused upon maintaining and further developing this software.
