Charles Browne, Brent Culligan and Joseph Phillips spent more than 3 years (from 2009-2013) working with the 288 million word Cambridge Academic Corpus in an effort to create a New Academic word List of core vocabulary for second language learners. Here is a little about them:
Dr. Browne is Professor of Applied Linguistics & TESOL and Head of the EFL Teacher Training Program at Meiji Gakuin University's English Department, a top-ranked private university in Tokyo, Japan. He is a well known expert in online language learning, especially as it applies to second language vocabulary acquisition and reading skills development, and publishes widely on the topics of English education in Japan, 2nd language vocabulary acquisition and online learning. He has just created a new free website for teachers and students interested in Extensive Reading called ER-Central.com which includes a cool tool for helping teachers to create their own graded reading materials called OGTE (Online Graded Text Editor). He has also served as Senior Science and Pedagogy Advisor for EnglishCentral, Senior Academic Advisor for GoFluent, and is co-founder and co-patent-holder of the language learning software developed for Word Engine.
Dr. Culligan, English Instructor at Aoyama Gakuin Women's Junior College, consistently ranked as the top Women's College in Japan, has more than 20 years university teaching experience in Asia and is assessment-based curriculum developer for award-winning university English language program. His areas of research include vocabulary acquisition, corpus linguistics, and language testing, particularly within the field of Item Response Theory. His work in word lists began in 1995 when Culligan, in collaboration with John Bauman, applied Bauer and Nation (1993) affix rules up to level 4 to create word families from the words in the General Service List word (West, 1953). They then ranked the word families using frequency data from the Brown corpus (Frances & Kucera, 1982) producing one of the most cited versions of the GSL. He has also served as Senior Science Advisor for WordEngine, and is a co-patent-holder of the language learning software developed for Word Engine based on his research.
