Caitlin Patricia Fischer completed a B.A.Sc. degree in Geological Engineering at Queen’s University with coursework focusing on geomechanics and geotechnical engineering. Caitlin’s work experience as a Rock Mechanics Specialist with the Vancouver Mine Stability Team at Golder WSP primarily involves geotechnical data processing and numerical modelling for the assessment of rockmass stability for underground mines, open pit mines, and waste dumps. Caitlin is currently working on her Ph.D., where she aims to utilize numerical modelling techniques to realistically represent jointed rock for the design of underground excavations (including ground support) to improve observational design procedures and risk assessment for rockbursting. Caitlin believes that her research is particularly important from a public safety standpoint, as rockbursting events often result in serious injury and fatality in the workplace.
