John Stewart holds a Ph.D. from the Department of Germanic Studies at U.T. Austin. His research fields include Germanic linguistics and language acquisition. John's prior experiences with conducting linguistic fieldwork and building a corpus of spoken language data explain his attraction to the Texas German Dialect Project. John worked on the project from Fall 2002 through Summer 2003. At that time he completed his dissertation entitled “The Fundamental Difference between Child and Adult Second Language Acquisition: a Longitudinal, Naturalistic Study of Parameter Resetting in Swedish Interlanguage.” He then accepted a position as lecturer at the Institute of Translation and Interpreting, University of Heidelberg, Germany. Since then, he has continued to teach translation studies at Heidelberg University and conduct research in Germanic linguistics. Inspired by his experiences with the TGDP among other things, he have branched out from his dissertation research topic of second language acquisition to do work on areal and contact linguistics, interlingual transfer and interference, and immigrant languages, contributing to the Eurolinguistics research program launched by Professor Sture Ureland of Mannheim, Germany.
