Biography

Richard is a cognitive scientist with an educational background in psychology and computer science. After working for several years in the software development industry, he completed a PhD at Flinders University in 2009, with a thesis that investigated computational models of the way in which children might be able to learn the parts-of-speech of their first language.

Richard is currently a Research Associate in the School of CSEM, working on the cross-institutional ARC/NHMRC project "From Talking Heads to Thinking Heads" and the ARC Discovery project "Heterodensity neuroimaging techniques for spatiotemporal identification and localization".His primary research interests relate to human and machine learning of language, and to the development of computer systems that are designed around the humans who will use them.
