Overview

Professor Michael O'Sullivan is a neuroscientist, neurologist and group leader at the Institute for Molecular Bioscience (IMB). His main research interest is the neurobiology of brain injury, with an emphasis on mechanisms of resilience and recovery of the brain after injury. His previous work has developed understanding in two broad areas:

• The cognitive neuroscience of memory and cognitive control – and how distributed and dynamic networks in the brain support these functions, which are often affected by injury.
• How injury alters network structure and function leading to symptoms in day-to-day life - and intrinsic mechanisms of neural adaptation that modulate the effect of injury

At the Institute for Molecular Bioscience, O'Sullivan is building a research program on cellular and molecular events that influence adaptation and recovery, including the role of innate immunity and glial cells. This program includes novel approaches to neuroprotection and the role of astrocytes as key regulators of glutamate and neuroinflammation. A major theme is identification of therapeutic targets, and evaluation of disease progression or treatment response in vivo, using advanced human imaging with MRI, PET and novel radiotracers. In addition to his Institute work, O'Sullivan leads clinical and biomarker projects in stroke and traumatic brain injury and is a member of the NHMRC Centre for Research Excellence in vascular mechanisms of cognitive impairment.

The group is at the forefront in the application of advanced techniques to investigate brain structure and function in vivo, including diffusion MRI and tractography, the use of functional MRI and EEG to examine to examine dynamic network interactions, and PET to examine neurochemistry.

Supervision

Professor O'Sullivan supervises PhD projects across multiple research areas, including clinical science, cognitive neuroscience, animal models and computational neuroscience (such as machine learning and deep learning algorithms for diagnosis and prediction of prognosis). Expressions of interest from potential PhD and honours students are welcome.

Brett Collins is an NHMRC Career Development Fellow and head of the Molecular Trafficking Lab at UQ's Institute for Molecular Bioscience. He was a lead investigator in the seminal structural studies of AP2, the protein adaptor molecule central to clathrin-mediated endocytosis, and has since defined the molecular basis for the function of critical proteins regulating membrane trafficking and signalling at the endosome organelle. His team is now focused on understanding how discrete molecular interactions between proteins and lipids control these processes in human cells.

Associate Professor Collins was awarded his PhD in 2001 and has published over 75 papers including in Cell, Nature, Nature Structural and Molecular Biology, Developmental Cell, and The Proceedings of the National Academy of Sciences USA, altogether cited more than 3100 times. He is the recipient of 3 prestigious fellowships, including a previous Career Development Award from the National Health and Medical Research Council and a Future Fellowship from the Australian Research Council, and was awarded the University of Queensland Research Excellence Award in 2008. In 2015 he was awarded the Emerging Leader Award of the ANZSCDB and in 2016 the Merck Research Medal from the ASBMB. He is currently the President of the Queensland Protein Group.
