Nick Spencer completed his BSc(Hons) in 1995 and then his PhD in Neurophysiology in 1998 at the Department of Physiology, Monash University, Australia. In 1998, Nick then moved to The University of Nevada School of Medicine, where he spent 10 years. In 2002, Nick obtained a 5 year grant with the NIH, to study intrinsic neural reflex circuitry in the gastrointestinal tract.

Since arriving at Flinders University 14 years ago, Nick has been a balanced teaching/research academic. Over this time, he been a Chief investigator on 15 NH&MRC project grants and 4 ARC Discovery grants ($10 million AUD). He was Chief Investigator-A on 11 of these 19 federally-funded grants. In 2022, he is Chief investigator-A on 2 NH&MRC project grants and 2 ARC discovery grants on gut-brain axis. In 2018, he published with Dr. Hongzhen Hu, the first wireless optogenetic control of the gut, in the leading journal Gastroenterology. Nick is interested in developing techniques that have been previously unavailable to the field to address major questions that have eluded scientific investigation.

Research in his laboratory is primarily directed to understanding the neurophysiological basis of pain pathways in visceral organs, and the neural control mechanisms that underlie control of the gut to brain axis. He has published more than 180 peer reviewed articles on autonomic neuroscience.

Nick was the Course Coordinator of the Bachelor of Medical Science degree from 2011-2015 and is currently Coordinator of Neuroanatomy for Year 2 Medicine.

In 2014, Nick was the Treasurer of the Australasian Neurogastroenterology and Motility Society (ANGMA)and in 2016, was elected President of ANGMA.

In 2022, Nick became Chair of Optogenetics Australia

Nick has worked with Vibrant (Israel), Ironwood Pharmaceuticals, Fonterra (N.Z), GlaxoSmithKline.
