Jeffrey Heinz (Ph.D. 2007, University of California, Los Angeles) is an associate professor at the University of Delaware. He conducts research at the intersection of theoretical linguistics, theoretical computer science, and computational learning theory. With Rob Goedemans and Harry van der Hulst, he helped develop the StressTyp2 database, which organizes and presents information on the stress and accent patterns in hundreds of languages around the world. Rob Goedemans (Ph.D. 1998, Universiteit Leiden) conducts research regarding the phonetics, phonology, and typology of stress in the languages of the world in general, and the languages of Aboriginal Australia and Indonesia in particular.

Currently, Rob is employed in the Departments of Communications and Information Management at the Humanities Faculty of Universiteit Leiden. Harry van der Hulst (Ph.D. 1984, Universiteit Leiden) specializes in phonology, which is the study of the sounds systems of languages, as well as the visual aspects of sign languages. He has published twenty-five books and over 130 articles.
