David Angell studied mathematics at Monash University and the University of New South Wales, Australia, earning a Ph.D. from the latter institution with a thesis on Mahler's method in transcendence theory. He has been a member of the academic staff in the School of Mathematics at UNSW since 1989, and has consistently received glowing evaluations of his teaching both from colleagues and from students. David has taught a wide variety of mathematics subjects, but his favourites have always been number theory and discrete mathematics. He is particularly interested in teaching students to produce proofs and other mathematical writing which are clearly expressed, logically impeccable and engaging for the reader. David is strongly committed to extension activities for secondary school students. He has for many years been the problems editor for Parabola, the online mathematics magazine produced by UNSW, as well as contributing a number of articles to the magazine. He has also given talks on a wide variety of topics to final-year secondary students. His text Irrationality and Transcendence in Number Theory was published by CRC Press, Taylor & Francis in 2022.

Beyond mathematics, David is an enthusiast for wilderness activities and has undertaken expeditions in Australia, Greenland, Nepal, Morocco and many other areas. He is a keen amateur musician, and is the founding conductor of the Bourbaki Ensemble, a chamber string orchestra based in Sydney, Australia.

Thomas Britz studied mathematics and physics at Aarhus University, M.I.T. and Queen Mary University of London. After receiving a Ph.D. in mathematics from Aarhus University, Thomas completed postdoctoral fellowships at Victoria University, BC, the Technical University of Denmark and the University of New South Wales. Thomas has been a member of the School of Mathematics and Statistics at UNSW Sydney since 2010 and is currently the president of the Combinatorial Mathematics Society of
