Mark Johnson is a Professor of Language Science (CORE) in the Department of Computing at Macquarie University. He is also the Chief Scientific Officer for VoiceBox Technologies Australia, which is a research and development laboratory located on the Macquarie University campus and run by Voicebox Technologies, an interactive voice technology company based in Seattle. The lab develops novel deep learning models to build the next generation of VoiceAI.
Mark was awarded a BSc (Hons) in 1979 from the University of Sydney, an MA in 1984 from the University of California, San Diego and a PhD in 1987 from Stanford University. He held a postdoctoral fellowship at MIT from 1987 until 1988, and has been a visiting researcher at the University of Stuttgart, the Xerox Research Centre in Grenoble, CSAIL at MIT and the Natural Language group at Microsoft Research. He has worked on a wide range of topics in computational linguistics, but his main research area is natural language understanding and syntactic parsing, and its applications to text and speech processing.
He was President of the Association for Computational Linguistics (ACL) in 2003, President of SIGDAT (the group that runs the EMNLP conference) in 2015, and is an Editor in Chief for the ACL's journal Transactions of the ACL and Springer's monograph series Theory and Applications of Natural Language Processing. Before returning to Australia, he was a professor in the Departments of Cognitive and Linguistic Sciences and Computer Science at Brown University from 1989 until 2009.
