Teaching Responsibilities 2019/20:
Term 1:
MA398 Matrix Analysis and Algorithms, Term 2: MA999 Fundamentals of Mathematical Modelling V - Industrial Mathematics

Research Interests: My primary research interests lie at the interface between scientific computing, numerical solutions for partial differential equations, physical systems modelling (in particular fluid mechanics and acoustics), asymptotic analysis and industrial mathematics.

I work on methodologies used to address technologically relevant problems in areas such as microfluidics, water retention on aircraft surfaces, spray atomisation and electrohydrodynamics. I am also active in a more general industrial mathematical modelling setting, with previous projects in computational acoustics (perfectly matched layers in particular), operational research and performance optimisation in flow-related devices (e.g. vacuum pumps, pesticide sprays). I often participate in Study Groups with Industry, as well as events within the UK Fluids Network as part of several Special Interest Groups.

I have in the past worked within the Oxford Mathematical Institute as Hooke Research Fellow (2017-2019) and the Department of Mathematics in Imperial College London (2011-2017). I maintain active ties with both institutions, as well as several other UK-based and international groups.
