Language Science Day aims to bring together the cross-departmental community of 200+ language science students and faculty to improve awareness of the rich opportunities for language science at the University of Maryland. “Language science” is to be understood broadly, to include cognitive, computational, engineering, clinical, theoretical, philosophical, biological, and educational approaches. The goal is to showcase research activities and opportunities, to make students aware of training possibilities, and to jump-start potential interdisciplinary connections. This is the fourth annual Language Science Day.
