Biography
Laurence Park received the BE (Hons.) and BSc degrees from the University of Melbourne, Australia in 2000, and the PhD degree from the University of Melbourne in 2004. He joined the Computer Science department at The University of Melbourne as a Research Fellow in 2004, and was promoted to Senior Research Fellow in 2008. Laurence joined the School of Computing and Mathematics at the University of Western Sydney as a Lecturer in Computational Mathematics and Statistics in 2009, where he is currently investigating methods of large scale data mining and machine learning.
