The User Advisory Committee (UAC) is an independent group that provides advice to the Australian Synchrotron Director on issues from a user perspective.

The role of the UAC is to:

  • represent Australian Synchrotron user interests to Australian Synchrotron management
  • provide advice and feedback on the operation and development of the synchrotron and beamlines
  • assist the Australian Synchrotron in providing feedback to users about synchrotron-related issues
  • give feedback on Australian Synchrotron processes involving users, such as the proposal process and induction procedures.

The UAC has seven elected members, along with the seven Program Advisory Committee Chairs. The members cover a broad national and regional spread together with diverse discipline mix related to the major branches of synchrotron science, and will represent the interests of the wide synchrotron user community in Australia.

Your UAC representatives are listed below.

 Assoc. Prof. Chris McNeill (Chair)

Monash University

I fell in love with synchrotrons in 2005 during my first synchrotron trip to the Advanced Light Source when as a post-doc. The thrill of doing science at a big facility, the science opened up by a tuneable high-brightness X-ray source, the number of papers that could be generated in a single week-long visit! Since then I have also worked at the Swiss Light Source, at Diamond and am now a regular user of the soft X-ray and SAXS/WAXS beamlines at the Australian Synchrotron where I use synchrotron X-rays to probe the structure of organic semiconductor thin films. Along with my passion for synchrotron science, I bring experience of working at other facilities and my time as soft X-ray PAC chair. I am committed to making the user experience at the Australian Synchrotron the best it can be, and to working with users and management to make it happen.


Dr. Anthony Chesman (Ex Officio)


Anthony Chesman obtained his PhD from Monash University in 2010, for his work on the synthesis and magnetic properties of 3d/4f high nuclearity complexes and ionic liquids. Anthony joined CSIRO in 2011 as an OCE Postdoctoral Fellow, investigating the use of non-toxic and earth abundant nanoparticles in the fabrication of solution processed solar cells, and is now continuing this work as the recipient of an ARC DECRA Fellowship. In 2014 Anthony became the Team Leader of the Nanomaterials and Devices Team in the Industrial Innovation Program of the Manufacturing Flagship. Anthony has extensive experience on the PD and MX beamlines at the Australian Synchrotron, and has also previously been a user of the Koala beamline (Laue Diffractometer) at ANSTO.


Dr. Stephen Holt (Elected Member)


Stephen is an instrument scientist co-responsible for neutron reflectometry at the Australian Centre for Neutron Scattering (ACNS). Stephen has extensive experience primarily with surface scattering from soft matter and biological systems with both x-rays and neutrons. Stephen’s x-ray scattering experience began in 1995 at the Research School of Chemistry, ANU where he was responsible for completing the construction of and making operational the first liquid surface x-ray reflectometer in Australia. His synchrotron experience began about the same time with experiments at the Australian National Beamline Facility, Tsukuba. In 1998 he was awarded one of the inaugural ASRP fellowships. Stephen has also undertaken experiments on a number of surface scattering beamlines at the NSLS, and the APS. Additionally he has performed neutron scattering experiments at five international facilities. He spent nine years at the ISIS neutron spallation source in the UK before joining the Bragg Institute, now ACNS, and therefore has gained a perspective on large-scale facilities from both ‘sides of the fence’.

After completing his studies, Jack won a Marie Curie Fellowship to conduct research at the University of Cambridge. Jack returned to Australia to join The University of Queensland in 2012 and became an ARC Future Fellow in 2014. In 2015 Jack won a QLD Young Tall Poppy Science Award for outstanding achievements in scientific research and communication. Outside science, Jack has served as a Director of the board of the Australian Youth Orchestra and a regional Credit Union in NSW. Jack has authored more than 140 publications including 3 book chapters, which have received over 2500 citations.

Dr. Peter Czabotar

Walter & Eliza Hall Institute

Co-chair,  Macromolecular crystallography (MX) PAC

Peter Czabotar is a Laboratory Head within the Structural Biology Division at the Walter and Eliza Hall Institute of Medical Research in Melbourne. His research focus is on the structural biology of proteins that control programmed cell death. For this work he employs the macromolecular crystallography beamlines, MX1 and MX2, at the Australian Synchrotron. He also has experience with beamlines at other facilities including the NSLS at Brookhaven, the ALS at Berkley, the SRS at Daresbury, the Photon Factory in Japan and the Swiss Light Source.

Prof. Roland De Marco

University of the Sunshine Coast

Chair, Soft X-ray (SXR) PAC

Professor Roland De Marco received his PhD in Chemistry / Physics from La Trobe University in 1992. He was awarded the 2008 RACI Lloyd Smythe Medal for excellence in research in Analytical Chemistry.

Roland De Marco is also an internationally recognized leader in the field of electrochemical sensors.  His major strength is in the field of electrochemical surface and interface analysis, and he has a strong track record of using state-of-the-art electrochemical and surface analytical techniques in the micro- and nano-characterization of electrochemical devices.  He has been recognized for his national and international leadership in neutron and synchrotron science through his current appointments on the Australian Institute of Nuclear Science and Engineering (AINSE) Materials, Structures and Dynamics Specialist Committee as well as the Chair of the Program Advisory Committee of the Soft X-ray beamline at The Australian Synchrotron.

Co-chair, Small and wide angle x-ray scattering (SAXS/WAXS) PAC


Dr. Mark Styles


Chair, Powder Diffraction (PD) PAC

Dr Mark Styles is a research scientist within CSIRO’s High-Performance Metal Industries program. Mark’s current research focus is on microstructure-property relationships in materials produced by metallic additive manufacturing techniques, however his research interests also include novel alloy development using combinatorial research methods and solid-state phase transformations in general. Mark’s background is in engineering design and materials characterisation, particularly via in situ X-ray and neutron powder diffraction techniques, and enjoys combining these skills to study materials under operational conditions. For example, during his PhD research (completed jointly at the University of Melbourne and CSIRO in 2012) Mark designed and built a novel molten salt electrowinning cell that allowed the growth of passivation layers on the anode material to be quantitatively measured in real time using energy-dispersive synchrotron powder diffraction.


Dr. Megan Wallace

Monash University

Chair, Imaging and Medical (IM) PAC



Assoc. Prof. David Beattie

University of South Australia

Chair, Infrared (IR) PAC

Dr. Amanda Edgley

University of Melbourne/St Vincent's Hospital

Chair, International PAC

Dr Amanda Edgley obtained her PhD from Monash University in 2001 and is currently a senior research fellow in the Renal and Cardiovascular Translational Research Group at the University of Melbourne, Department of Medicine, St Vincents Hospital. Her research interests focus on developing and evaluating novel compounds for the treatment of pathological inflammation and fibrosis in diabetic and non-diabetic kidney, heart and eye disease. Inflammation and fibrosis underlie the decline in organ function in many cardiovascular conditions. Dr Edgley has had experience using synchrotron radiation microangiography techniques to study aspects of coronary microvascular function in health and disease. She has also utilised synchrotron short angle x-ray scattering (SAXS) to investigate regulation of myocardial cross bridge function.
