Summary
Adrian is currently leading the development and implementation of new algorithms for next-generation FWI technology (XWITM) at S-Cube, to eliminate human bias and provide a step-change in seismic imaging quality.
He gained his degree in Mathematics with Astronomy from the University of Leicester. He then became a Research Associate (later Fellow) in the Applied Modelling and Computation Group, before moving to S-Cube.
His main academic interest is in the development of novel computational & mathematical techniques for a range of applications. At Imperial this most recently included 3D FWI, which led to the spin-out company S-Cube. However, over the years, this also covered Computational Radiation Transport, Reactor Physics, Parallel Computing, Mesh Adaptivity, Nuclear Criticality Safety and Scientific Visualisation.
While at Imperial, he also developed much of the adaptive mesh technology originally used within Fluidity and the Imperial College Ocean Modelling software (ICOM), and played a key role, along with Dr C.R.E de Oliveira, in developing many of the methodologies currently implemented in EVENT, including: raytracing in near-void regions for AGR and MAGNOX reactor modelling, time-dependent radiation transport (nuclear criticality) and the MBM preconditioner for the main conjugate gradient solver in EVENT.
