Prof. Dr. Peter Walla PD

Department Head of Psychology

(Habilitation in Biological Psychology and in Cognitive Neurobiology)

conjoint Professor at Newcastle University (Australia),               Senior Research Fellow at Vienna University (Austria)

Chief Editor of "Cogent Psychology" (scopus and ISI listed)

After a solid training in Zoological Neurophysiology on a single neuron level (spider eye photoreceptors) Peter started to focus on human memory functions by utilising brain imaging methods with high temporal resolution. Various abroad visiting research (Japan, Scotland, Australia) at renowned Universities strengthened his education in Cognitive and Affective Neuroscience and gave him the essential skills and expertise to get his PhD awarded plus two further postdoctoral degrees, one in Cognitive Neurobiology (Habilitation at the Vienna Medical University) and the other in Biological Psychology (Habilitation at the Vienna University).

In 1998, in the frame of his dissertation he published a Nature article demonstrating neurophysiological correlates of non-conscious word memory. Since then he strongly focuses on non-conscious processes in general (cognitive and affective). The brain knows more than it admits to our conscious mind and now we have access to this knowledge via Neuroscience Technology.

Meanwhile, Peter is not only an active Biological Psychologist and Neuroscientist, but also offers his expertise as a Neuroconsultant (www.neuroconsult.com.au).
