Biography:

Louisa Michael received her BSc. in Mathematics (with Applied Mathematics and Theoretical Physics) from Imperial College London in 2007. She then studied Part III Mathematics (CASM) at the Department of Applied Mathematics and Theoretical Physics (DAMPT) in the University of Cambridge . She received a PhD in Physics (Cavendish Laboratory) from the University of Cambridge in 2012 under the supervision of Dr. Nikolaos Nikiforakis. She has held a postdoctoral position jointly supported by  Jaguar Land Rover and the UK-EPSRC grant EP/K014188/1 as part of the jointly funded Programme for Simulation Innovation. She currently holds a postdoctoral position funded by DSO National Laboratory. She is also involved in other projects funded by UK-EPSRC (modelling of detonators for optimisation of their design in mining, equation of state and reaction rate models development) and Boeing (Lightning strike on aircraft).

Research interests:

Louisa Michael's research is primarily on multi-physics, multi-material, multi-scale and multi-phase problems. In particular, she is interested in developing appropriate governing equations and associated numerical algorithms to accurately simulate such systems. She focuses on the form of the equations that allow the simultaneous solution of Euler, reactive flow and elastoplastic systems of equations on the same grid, with the same finite volume methods. She is also developing mixed Riemann solvers for such systems to ensure the correct communication of information across material interfaces. Of particular interest are also combustion problems and their mathematical representation and numerical solution. 

Louisa has worked on numerous industrial funded applications including: sensitization of condensed-phase explosives (ORICA), multi-material modelling (Qinetiq), multi-phase flows and fluid-structure interaction (Schlumberger), HPC & Simulation Knowledge Mining and Abstraction, wading, internal combustion engines, crash and fuel initiation (Jaguar LandRover).
