Here is his bio from his university page:
Elliot Judd's major area of research is in language policy, especially in the United States. More specifically, he is interested in the socio-political factors that have shaped American language policy, both past and present, in the areas of teaching English to immigrants, teaching foreign language to native-born Americans, dialect usage, and policies that promote the maintenance or loss of languages other than Engllish, including programs dealing with bilingual education. He has also studied language policies and practices for English teaching in other countries around the world. Another area that he has written on is TESOL methodology, and curriculum and materials development for both adults and children. He has helped design materials and teacher-training programs for use in adult, community-based education programs, content-based mathematics for ESL elementary students, and in academic programs for adult ESL/EFL learners. Judd served as President of the International TESOL Association from 2006-07.
