Mark McGuinness is Emeritus Professor of Applied Mathematics in the School of Mathematics and Statistics at Victoria University of Wellington. His research interests are driven by challenges presented at Mathematics in Industry workshops and by various geophysical, industrial, and biological applications, including steaming Surtseyan volcanic ejecta, modelling the freezing of sea ice, chaotic dynamics, fragmentation of volcanic rock, cooking crispy cereals, the use of microwaves to measure moisture content, and coal volatilisation. He enjoys using differential equations to model and explain the behaviour of heat and mass transport problems. Mark is co-author of the book "Chaos", published by Springer in 2019.

Mark's background in geothermal reservoir modelling has led to the development of SwelFlo, a software package for simulating flows in a geothermal well. SwelFlo provides a digital twin of an existing geothermal well. The flows can be single or multiple phases, with noncondensable gas present, for production flows, or injection of liquid phase. SwelFlo runs in Windows, and produces quick plots of downhole profiles of pressure, temperature, and velocity, as well as output curves and flash depth computation, for wells with multiple feeds and varying casing sizes and inclinations. Apriori Monte Carlo simulations give distributions of well deliverability, and historical matches to well data are easily computed and used to forecast future geothermal well capabilities.

Mark remains a member of the Mathematics in Industry New Zealand (MINZ) Reference Group, with responsibility for organising the annual MINZ Study Group that brings together selected industrial problems with academics and students to solve problems arising in New Zealand industry in a brainstorming week of amazing mathematics. Mark is regularly asked to Moderate at the Mathematics in Industry Study Groups held annually in Australia. He has been Chair of ANZIAM, the over-arching group of industrial and applied mathematicians in Australia and New Zealand that also oversees the Mathematics in Industry Study Group held each year in Australia, and is currently Deputy Chair of ANZIAM. Mark is a Fellow of the New Zealand Mathematical Society, and has served as Treasurer and Council Member of that Society a number of times.
