Dr Andrew Delaney

BSc, BSc(Hons), PhD, GCEd.

Dr Andrew Delaney is a senior lecturer based in Orange. After completing his undergraduate studies in organic chemistry and biochemistry at the University of Newcastle, He completed a PhD at the John Curtin School of Medical Research (Australian National University), studying the pharmacology of GABA receptors in the central amygdala using electrophysiological techniques. He then completed a postdoctoral fellowship at the Vollum Institute in the US, prior to returning to Australia to accept an ARC Australian Post-doctoral Fellowship at the Queensland Brain Institute. He has been teaching and researching in Neuroscience and physiology since 1998 and currently teaches into neuroscience and anatomy and physiology subjects in the Faculty of Science. His research is currently investigating the regulation of emotional processing by oxytocin, noradrenergic control of synaptic transmission in the amygdala and the effect of diet on behaviour, and he is currently funded by the NHMRC.

Teaching

Dr Delaney teaches into numerous human anatomy and physiology subjects (BMS 129/130. BMS191/192), pathophysiology subjects (BMS291/292 and BMS310), and into two neuroscience subjects (BMS321 and BMS329). He also regularly provides Guest lectures in clinical science and medical science subjects. He currently supervises 2 PhD students.

Research

Dr Delaney's primary research focus is the study of neuronal mechanisms in synaptic transmission and plasticity. My research investigates the role of neuromodulation and plasticity in the circuits that mediate pain and emotional processing in the amygdala.

He also investigates the cellular mechanisms of neuro-active pharmacology and the electrophysiology and micro neuro-anatomy of the amygdala and its connections with the brainstem and forebrain.
