Fionn Patrick Edward Dunne FREng FIMMM is a professor of Materials Science at Imperial College London and holds the Chair in Micromechanics and the Royal Academy of Engineering/Rolls-Royce Research Chair. [2] Dunne specialises in computational crystal plasticity and microstructure-sensitive nucleation and growth of short fatigue cracks in engineering materials, mainly Nickel, Titanium and Zirconium alloys. [3]

Early life and education

Dunne completed a Bachelor of Science at the Department of Mechanical Engineering, University of Galway, [4] and Master of Engineering degree from the Department of Mechanical Engineering, University of Bristol by 1989, [5] before moving to the Department of Mechanical and Process Engineering, University of Sheffield, for a Doctor of Philosophy in Computer Aided Modelling of Creep-cyclic Plasticity Interaction in Engineering Materials and Structures. [6] [7]

Research and career

In 1994, Dunne was appointed as a Postdoctoral research associate in the Department of Mechanical Engineering, University of Manchester (UMIST), before being appointed a Research Fellowship at Hertford College, Oxford and the Department of Engineering Science, University of Oxford from 1996 until 2012. [8] He became the deputy head of the department but moved to Imperial College London in 2012. He is an Emeritus Fellow of Hertford College, Oxford. [9]

While in Oxford, Dunne was part of the Materials for fusion & fission power program. [10] He led the Micro-mechanical modelling techniques for forming texture, non-proportionality and failure in auto materials program at the Department of Engineering Science, University of Oxford between October 2011 and June 2012, [11] when he moved the grant with him to the Department of Materials, Imperial College London from June 2012 until it ended in March 2015. [12]

He also led the Heterogeneous Mechanics in Hexagonal Alloys across Length and Time Scales (HexMat) program, which was Engineering and Physical Sciences Research Council (EPSRC) funded at a value of £5 million between May 2013 and November 2018. [13] Dunne was the director of the Rolls-Royce Nuclear University Technology Centre at Imperial College London. He is part of a £7.2 million program on Mechanistic understanding of Irradiation Damage in fuel Assemblies (MIDAS) that is funded by Engineering and Physical Sciences Research Council until April 2024. [14]

As of November 2022, Dunne is a professor of Materials Science at Imperial College London and holds the Chair in Micromechanics and the Royal Academy of Engineering (RAEng)/Rolls-Royce Research Chair. He is also a Rolls-Royce consultant, and an honorary professor and co-director of the Beijing International Aeronautical Materials (BIAM). [2]

Dunne's research focuses on computational crystal plasticity, [15] discrete dislocation plasticity, [16] and microstructure-sensitive nucleation and growth of short fatigue cracks in engineering materials, [17] [18] mainly Nickel, [19] Titanium, [20] [21] and Zirconium [22] alloys.

Awards and honours

In 2010, Dunne was elected a Fellow of the Royal Academy of Engineering (FREng). [2] In 2016, he was awarded the Institute of Materials, Minerals and Mining (IoM3) Harvey Flower Titanium Prize. [23] In 2017, Dunne's Engineering Alloys team shared the Imperial President's Award for Outstanding Research Team with Chris Phillips’s team. [24]
