Josh Arnold

Joshua earned his undergraduate degree in Engineering (Software) from the University of Queensland. He began his research career developing social behaviours for a rat sized robot (the iRat) to facilitate interactions between the robot and real rats. Joshua completed his PhD in computational neuroscience under the mentorship of Prof. Janet Wiles. This work focused on the role of time in neural computation and in particular focused on how delays between neurons can be used as a functional learning rule. He then joined the Scott Lab at the Queensland Brain Institute where his work focuses on computational models of brain-wide calcium imaging data from the zebrafish model. computational neuroscience, neural computation, brain-wide calcium imaging data, zebrafish model, spiking neural networks, conduction delay plasticity
