Professor Stephen William Bigger
Professor, College of Engineering & Science
Professor Stephen W. Bigger graduated with a Bachelor of Applied Science and PhD from the University of Melbourne. His PhD was awarded in the applied chemistry field of polymer photo-degradation and stabilisation. After completing his PhD he was appointed as a senior tutor and then lecturer in physical chemistry at the University of Melbourne where he worked for six years before taking up an academic position at Victoria University in 1991.
He has published over 250 refereed papers and conference presentations in his research field and has held several leadership positions including the Head, School of Molecular Sciences and the Acting Executive Dean of the former Faculty of Health, Engineering and Science at VU.
Professor Bigger is a researcher of international standing in the field of polymer degradation and stabilisation and has also published widely in the refereed educational literature in chemistry. He has served on committees for the advancement of chemical education such as the Chemistry Education Association executive committee and has been appointed as subject specialist vetter for VCE Chemistry examinations by the Victorian Curriculum Assessment Authority.
He has been a recipient of the Vice Chancellor's Peak Award for Teaching Excellence and the Vice Chancellor's Peak Award for Research Supervision at Victoria University as well as an Australian Learning and Teaching Council citation for developing and disseminating over a sustained period original and innovative approaches to teaching chemistry to students with diverse backgrounds and interests.
