Mark Hildyard has over 23 years research experience in rock mechanics and seismology. He has worked in academia since 2005. Prior to that, he spent 16 years in applied research for the mining industry working for the Chamber of Mines Research Laboratories and the Council for Scientific and Industrial Research in South Africa. This work focused on understanding and improving the rockburst problems experienced in deep-level gold and platinum mines, and included developing numerical models to study seismic wave propagation around underground openings and their interaction with fractured rock. Much of his research has focused on producing full waveform models, which match and explain the underlying system of fractures. In 2005 he received the Manual Rocha Medal from the International Society for Rock Mechanics (http://www.isrm.net/gca/?id=288) for this work. He is (along with Peter Cundall) a principal developer of the program WAVE, a three-dimensional finite difference code used to model seismic wave propagation in the vicinity of underground openings in fractured rock. He has applied these models to a range of interesting problems including understanding source mechanics in earthquakes and in rockbursts, modelling vibrations due to underground or surface blasting, improving the interpretation of fractures from seismic waveforms (for various projects in petroleum exploration, mine stability, and the stability of nuclear waste repositories), and even for detecting fractures in railway lines using the rail line as a waveguide. His research interests encompass developing novel numerical models and applying such models in any fields involving elastic waves or fractures.
