Dr. Matt Kanwit was honored to present the keynote lecture at Georgetown's 16th Graduate Portuguese and Hispanic Symposium. The conference's theme was "Thresholds: Disciplinary Crossroads," and Dr. Kanwit's talk centered on how the fields of sociolinguistics and second language acquisition (SLA) can mutually inform each other in beneficial ways, in addition to how two approaches within SLA (concept-oriented and variationist approaches) can contribute to a whole greater than the sum of its parts. The talk also provided an opportunity to share information about exciting projects with collaborators at Pitt and other institutions. Dr. Kanwit is grateful to the organizers for all of their hard work in planning an excellent conference with such engaging events.
