Emeritus Professor Hibbert occupied the Chair of Analytical Chemistry at the University of New South Wales in Sydney from 1987 until his retirement in 2013. 
His research interests are in electroanalytical chemistry and chemometrics and metrology in chemistry, but he also does a sideline in expert opinion, scientific fraud and presenting science to the public.

He has published around 280 papers, 5 books and 3 patents. His recent books are, Data Analysis for Chemistry: An Introductory Guide for Students and Laboratory Scientists (Oxford University Press, New York, 2005, 192 pp) written with Justin Gooding, and Quality Assurance in the Analytical Chemistry Laboratory, published by Oxford University Press in 2007. Professor Hibbert won the Ollé Prize of the RACI in 2008 for this text.

He is past Chair of the Analytical Division of the RACI, past chair of the IUPAC Analytical Division, and past president of the Royal Society of New South Wales. He is currently the Secretary of the Interdivisional Committee for Terminology, Nomenclature and Symbols of IUPAC, and editor of the Orange Book (Compendium of Terminology in Analytical Chemistry). Professor Hibbert is also a member of advisory committees for NATA and represented IUPAC at the JCGM-WG1 which is responsible for the Guide to the “Expression of Uncertainty in Measurement”.

In 2018 he became a member of the Order of Australia (AM) for “significant service to science in the discipline of chemistry, to professional societies, and to sport through illicit drug profiling”
