Scholarly Interests

Language and social interaction:

  • Conversation analysis
  • Classroom discourse
  • Advice giving and receiving
  • Parent-child interaction
  • Communicating with the public


Language and Social Interaction Working Group (LANSI)

LANSI was established in Fall 2010 to bring together students and scholars in the larger metropolitan area of New York working on naturally-occurring social interaction. As a relatively new venture sponsored by The TESOL and Applied Linguistics Program here at Teachers College, Columbia University, LANSI pursues two goals:

(1) create a space for analytical workouts: for the past four years, we have been hosting monthly data sessions, where students and professors work side by side as colleagues towards the common goal of becoming better analysts (If you’re interested in joining us, check our website at www.tc.edu/lansi for schedules and locations); 

(2) provide a forum for and promote dialogs among analysts who work within the various areas of language and social interaction. Through LANSI, we hope to engage in substantive conversations that would enrich our understandings--not only of our common interest, but also of each other.
