About Me
I am a PhD student supervised by Dr Gihan Mudalige (University of Warwick) and Dr Robert Manson-Sawko (IBM Research). My PhD is an iCASE studentship funded by the UK EPSRC and IBM Research UK. Before starting a PhD with the High Performance and Scientific Computing Group at Warwick, I graduated with a First-Class BSc in Computer Science at the University of Warwick, receiving an award for best overall graduating BSc student in Computer Science.
Research
My research is focused on developing high-order computational fluid dynamics (CFD) methods for multiphase flows, flows consisting of two or more fluids in different phases, that are suitable for high performance computing (HPC). Currently I am looking at discontinuous Galerkin methods to provide the high-order discretisation and the level-set method to represent the interface between the fluids. A key aim of this research is to produce a performance portable library that can support the development of multiphase CFD codes on a wide range of HPC resources.

Projects
In addition to my PhD research, I contribute to the following open-source HPC projects:
- Tridsolver - A HPC library for solving batches of tridiagonal matrices on CPU and GPU clusters.
- OPS - A domain specific language that provides performance portability for structured mesh applications.
- OP2 - A domain specific language that provides performance portability for unstructured mesh applications.
Teaching
As a senior graduate teaching assistant, I have been involved with the delivery of the following modules:
