Professor Scott McCue is Academic Lead for Development and Diversity in the School of Mathematical Sciences.

**Background:** Scott McCue was awarded a PhD in Applied Mathematics from the University of Queensland in May 2000. His PhD supervisor was Professor Lawrence Forbes, who is now at the University of Tasmania. Scott was a Postdoctoral Research Fellow at the University of Nottingham from 1999-2001, under the supervision of Professors David Riley and John King. He was then a Postdoctoral Research Fellow at the University of Wollongong from 2002-2004 under the supervision of Professor James Hill, who is now at the University of South Australia. In 2004 Scott took up a position as Lecturer in Applied Mathematics at Griffith University. He moved to QUT in 2007 as Lecturer in Mathematics, was promoted to Senior Lecturer in 2009, Associate Professor in 2012, and Professor in 2016.

In 2009 Scott was awarded the JH Michell Medal. In 2019 he was awarded the EO Tuck Medal. In 2019 he was a Simons Visiting Fellow at the Isaac Newton Institute of Mathematical Sciences at the University of Cambridge.
