He has extensive court experience in Australia and overseas (including UK, Hong Kong, Singapore, and Bermuda) spanning a period of over twenty-five years.  He has provided expert reports on a wide range of document examination matters including examinations of signatures and handwriting (both of which include foreign script examinations), stamp impressions, sequences of writing, photocopy and fax origins, typewriting and document alteration and manipulation.

Steven holds the degrees of Bachelor of Science and Doctor of Philosophy in Chemistry, University of Sheffield and is a former document examiner with the London Metropolitan Police Forensic Science Laboratory. Whilst there, Steven recognised the potential of the original ESDA research and was a key figure in ensuring on-going research which resulted in the development of the ESDA for document examination.

Steven has a strong interest in scientific research on various aspects of document examination.  He has presented scientific papers on many occasions at meetings both in Australia (ASFDE Inc., ANZFSS) and overseas (ASQDE) on forensic science and document examination. His interests include relative timing of document entries, statistics as applied to document examination, electronic (biometric) signature and handwriting technology and the fundamentals of scientific evidence presentation. He is a co-author of the chapter “Document Analysis - Handwriting” in the Encyclopaedia of Forensic Science (Academic Press, 2000). He is also author or co-author of many scientific papers, many of which pertain to document examination.
