I am currently a Research Scientist in the Energy unit at CSIRO. I primarily work on the stage 3 CO2 injection at the CO2CRC Otway field site, developing pressure tomography plume inversion techniques. I am also working on physics driven approaches for understanding multiphase flow in the subsurface at a range of length scales, from the pore to continuum.

I use a combination of theory, high-precision numerical methods and carefully designed laboratory experiments to understand the multiphase flow of fluids through the subsurface at changing spatial and temporal scales:Pore scale: Understanding fundamental fluid-fluid interactions across unstable interfaces, in particular viscous instabilities and capillary pressure.Core scale: Characterising multiphase flow through heterogeneous, subsurface rock cores using a combination of X-ray CT scanning and high-fidelity 3D numerical simulations.Field scale: Utilising large scale simulations incorporating upscaled heterogeneous functions to understand fluid migration and trapping in subsurface reservoirs.Through this combined multi-scale approach, informed models and predictions can be made regarding the sustainable use of energy resources at large scale. I have expertise in analysing large datasets with HPC simulations, creating novel numerical methods and the application of state-of-the-art core flooding experiments with X-ray CT scanning.I am part of the Subsurface CO2 group in the Department of Earth Science & Engineering at Imperial College London. I am currently working on three major projects related to CCS:1. NERC NE/N016173/1 project, investigating the impact of heterogeneity across length scales in subsurface CO2 flow. Developing new characterisation workflows for heterogeneous rock cores. Scaling heterogeneities from pore-field scale.2. CMC field research station project, utilising new unsteady-state core flooding methodology to extract heterogeneity information for ultra-low permeability (<1 mD) rock cores. 3. MESMERISE UK project developing semi-analytical pressure build-up equations to describe multi-well CO2 injection into subsurface aquifers.

During my Ph.D. my research focused on understanding the viscous fingering instability, using theory and numerical modelling of immiscible displacement in Hele-Shaw cells. The viscous fingering phenomena in Hele-Shaw cells is an archetype problem in fluid dynamics, and allows the rigorous investigation of interface dynamics that can then be translated to more complex subsurface flows in 3D permeable media. This research stemmed from the need to understand the interfacial dynamics occurring during CO2 injection into subsurface aquifers, which are fundamental to the successful prediction of plume migration and storage of CO2 in sequestration processes. The research was funded through a doctoral training grant at the University of Nottingham from the EPSRC - Grant number EP/L50502X/1: Energy – Carbon capture and storage.During the Ph.D. I developed a novel boundary element method to solve Darcy flow in a Hele-Shaw cell using a hypersingular integration subtraction technique. Following from this, I also developed a radial basis function – finite collocation method with adaptive quadtree dataset to solve transport processes for moving interface problems. As well as the EPSRC doctoral training award, I also worked for the PANACEA and MUSTANG EU projects on CO2 capture and storage.

For a couple of months I worked directly with two PhD students aiding them on implementing their high level robotic control algorithms. This involved writing low to medium level control programmes for stepper motors and servo motors to create a walking robot and a snake arm robot. The low level kinematic and dynamic control that was produced allowed the robots to work together to provide in-situ repair of Rolls-Royce jet engines. The work involved writing efficient code that allowed the robot to respond in real-time, providing feedback to higher level systems that controlled the overall gait of the robot. The programming was implemented using Labview, with both real-time and FPGA systems being developed.

In the summer of 2011 I took part in a research placement scheme at the University of Nottingham where I conducted research into the Ballbot. The project involved dynamically balancing a 20kg robot on top of a spherical ball using inverted pendulum theory. By the end of the placement the Ballbot was able to balance indefinitely and re-stabilise after significant perturbations. The sensing algorithm was achieved via a sensor fusion technique implementing gyroscope and accelerometer readings to create a clean, non-drifting signal. The project later won two commendations for the 'Interns Choice Award' and the 'Best Designed Poster Award'.For a video of the Ballbot in action follow the link below:

I had several roles as the store was fairly small so I was required to work in all the different sections including the bike hut, parts, and travel and leisure. My main roles included assembling and repairing bikes, mixing paints, making number plates, installing audio equipment into cars, advising customers on Sat Navs and generally manning the shop floor.

My main duties involved working on the tills, maintaining stock in the store and generally helping customers on the shop floor.
