Dr. Sebastian Oberst, University of Technology Sydney, Centre for Audio, Acoustics and Vibration, Faculty of Engineering and IT; - Dr. Oberst works as Senior Lecturer at the newly founded Centre for Audio, Acoustics and Vibration (CAAV) and is Chief Investigator on several prestigious Australian Research Council grants. In 2017 he received the highly esteemed Junior Research Prize awarded by the European Association of Structural Dynamics (EASD) in the category "Development of Methodologies for Structural Dynamics". This prize follows the JSPS Award (2016) nominated by the Australian Academy of Science and an Australia Award/Endeavour Postdoctoral Research Fellowship (Australian Government, 2015) to work at the Imperial College London/Rolls-Royce Vibration University Technology Centre. Dr. Oberst led a DFG Priority Program (SPP1897) project in Applied and Theoretical Mechanics at the Technical University Munich; prior to this he worked as Research Associate then Space Engineer (Mechanical Antenna Design, Buccaneer Risk Mitigation Mission) at the UNSW Canberra from 2011 to 2016. Dr. Oberst received his Ph.D in Mechanical Engineering from The University of New South Wales in 2011 on his research on friction-induced instabilities and specialised since then in nonlinear dynamics of friction processes, as well as nonlinear time series analysis and signal processing, as applied to biotremology and micro-vibrational communication of insects.

Dr. Benjamin Halkon, University of Technology Sydney, Centre for Audio, Acoustics and Vibration, Faculty of Engineering and IT; - Dr. Benjamin Halkon is an experimentally-focuseddynamicist specialising in the development and industrially relevant application of non-contact measurements techniques and technologies primarily for the determination of structural vibration characteristics. Dr.Halkon joined UTS as a Senior Lecturer in the Faculty of Engineering & IT in 2017 and has been a core member of the Centre for Audio, Acoustics and Vibration therefrom. He has held the position of Deputy Head of School (Teaching & Learning) in the School of Mechanical and Mechatronic Engineering since early 2018 and has established, and is Academic Lead for, the LDV Lab at UTS Tech Lab - a unique facility within the region. Dr.Halkon has secured and completed many industry- and government-funded research projects and has supervised several post-doctoral and Ph.D (HDR) researchers and many UG/PG student projects in support of these. He has authored over 50 peer-reviewed articles and has contributed to policy change through his research and he is an Engineering Council accredited chartered mechanical engineer (CEng) and a Fellow of the Institution of Mechanical Engineers (FIMechE), a Fellow of the Institution of Engineers Australia (FIEAust) and chartered professional engineer (CPEng) and a Member of the Australian Acoustical Society (MAAS).

Dr.Jinchen Ji, University of Technology Sydney, School of Mechatronic and Mechanical Engineering, Faculty of Engineering and IT; - Dr.Jinchen Ji is a leading research scientist in the general areas of dynamics, vibration, and control, with over 110 journal publications. He has high-level expertise in dynamic modelling, vibration control, coordination control, synchronization and consensus control, noise control, condition monitoring, signal analysis, fault diagnosis, fatigue analysis, performance evaluation and energy consumption, and their applications to key problems in wind power industry, mining industry, manufacturing industry, agricultural industry and defense industry. He has been involved in a wide range of research projects which were financially supported by various government funding agencies and industry partners, in the fields of dynamic modelling, vibration analysis, vibration control, fatigue analysis, stability analysis, FEM analysis, and robotic systems.

Dr. Ji is an Associate Editor for two top international journals, namely, International Journal of Bifurcation and Chaos, and Journal of Vibration and Control. He is also an assessor and external reviewer for Australian Research Council ARC grant applications, Hong Kong RGC grant applications, and European Grant applications. He has been invited to be a session chair in many international conferences. He has also been invited to be a reviewer for over thirty international journals.

Dr. Terry Brown, University of Technology Sydney, School of Mechatronic and Mechanical Engineering, Faculty of Engineering and IT; - Dr. Terry Brown is a teaching focussed academic with a wide technical background and with interests and expertise in several areas. Dr. Brown joined UTS as an Associate Lecturer in 1995 and is now Senior Lecturer and Program Coordinator for Mechanical Engineering in the School of Mechanical and Mechatronic Engineering in the Faculty of Engineering and IT. He has taught in over 15 different subjects, made major contributions to establishing new courses and curriculum redevelopment and has received awards for his contribution to, and excellence in, teaching and learning. He has secured and completed, on his own and in partnership with others, several industry and government funded research and consultancy projects. These have been primarily in the areas of structural simulation and analysis and experimental verification and validation. Dr. Brown has also published widely, including in engineering education, biomechanics and vibration.
