Dr Meurig Gallagher is an applied mathematician and Centre Fellow at the Centre for Systems Modelling and Quantitative Biomedicine. Meurig’s research concerns how mathematical modelling can be used to extract informative and accurate information from biomedical and clinical imaging data sets. He is particularly interested in creating tools for researchers and clinicians to use, and has released the software packages FAST – the world’s first fully automated system for high-throughput tracking of sperm flagella (www.flagellarcapture.com) and NEAREST – a meshfree, regularised stokeslet code to solve Stokes flow problems in MATLAB (www.gitlab.com/MeurigGallagher/NEAREST).

Meurig spends a lot of time thinking about how the application of fluid dynamic modelling can help tackle problems in male fertility, a global problem that can have a direct impact on the quality of life for people everywhere. In 2018 Meurig was awarded the Iwan Lewis Jones Young Scientist prize (British Andrology Society) for his work developing FAST.
