Dr Jeff Gates's research interests are in: (a) Engineering failure analysis and forensic metallurgy; (b) Abrasive wear and wear-resistant alloys.
Dr Gates received his PhD from Monash University in 1985 and spent 15 years as an academic and senior researcher at the University of Queensland before starting UQ Materials Performance. He has been the Principal of UQMP (http://www.uqmp.com/) since its inception in 1998.
Dr Gates current long-term research projects are in the fields of:
- Development of white cast irons with improved abrasion resistance and fracture toughness
- Development of a suite of new-generation abrasive wear tests with verified predictive ability
- Development of methodologies for improving resistance to fatigue failure in machinery, including railway axles and conveyer drives
- Understanding the mechanical and metallurgical factors controlling the incidence of fires of electrical origin and other electrocutions

Research interests
-
Dr Gates main research interests are:
(a) Abrasive wear processes and wear mitigation, with a focus on the mining and minerals industries. Development of industrially-realistic wear testing devices. (b) Metallurgy & properties (fracture & wear) of high-Cr white cast iron and other wear-resistant ferrous alloys. (c) Engineering failure analysis and forensic metallurgy.
Research impacts
Dr Gates's work in engineering failure analysis and forensic metallurgy over the last 18 years has led to a national profile as an expert in this field. The professional consultancy and contract research business UQ Materials Performance, which he founded and directs, has gained a reputaiton as a unique resource for the rigorous investigation of component failures, especially those with major adverse consequences (escalating from financial losses to injuries, fatalities and even multiple fatalities). In this context Dr Gates has acted as an expert witness in numerous litigation cases and industry tribunals. He gave evidence at the 2009 Victorian Bushfires Royal Commission, and was a key witness in three of the subsequent Class Action lawsuits, most notably the Kilmore East - Kinglake class action, which was the largest court case in Victoria's history.
