Julien Epps

I am an Associate Professor in Signal Processing with the School of Electrical Engineering and Telecommunications at The University of New South Wales, Sydney, Australia. I also have a joint appointment as a Principal Researcher with National ICT Australia, in the ATP Laboratory, where I work on methods for the real time measurement of cognitive load using behavioural and physiological signals. My research interests include applications of speech modelling (in particular to speaker recognition and emotion recognition from speech) and genomic signal processing (in particular sequence analysis). I have also worked on aspects of human computer interaction, including multimodal interfaces and computer-supported cooperative work.
