Dr. Brummer has 36 years of experience in geomechanics consulting, practical mining applications, research and academia. His areas of specialization are all aspects of the behavior of highly stressed rock in deep mines or in extensively mined workings. He also has expertise in rockbursts, the design of microseismic and general instrumentation systems, the design of backfill and backfill systems, and particularly in the optimization of mining layouts to reduce risk and maximize value. He is the author of over 50 technical articles. Dr. Brummer is a Registered Professional Engineer in Canada (Ontario, Saskatchewan & NWT), a Designated Consulting Engineer with Professional Engineers Ontario and is a Director of Itasca Canada.
Mr. Cotesta has over 16 years of experience working on many aspects of geomechanics design for mine evaluation studies (scoping through execution), covering a wide range of mineral deposits for both greenfield and brownfield projects. His experience on these types of projects involves collection, analysis and interpretation of site characterization data, integration and analysis of multi-disciplinary datasets (geological, mine planning/production, geomechanical), sequence evaluation and optimization, stope and crown pillar design, numerical modelling, model calibration, trade-off studies and mining method evaluation. Mr. Cotesta is a Registered Professional Engineer in the province of Ontario and is a Director of Itasca Canada.
Dr. Tatyana Katsaga is a Geomechanics expert with a Ph.D. in civil engineering. Her area of expertise is on the mechanics and numerical simulation of continuum and discrete media. She has more than 15 years of research and consulting experience, and has provided consulting on many projects including mining (e.g., deep mines, block cave mining, pillar stability, optimization of mining layouts), nuclear waste storage, geothermal energy and petroleum. Dr. Katsaga also specializes in geophysical data acquisition, including advanced processing and interpretation
Mr. Paudel (Registered professional engineer in Ontario) has more than seven years of experience in geomechanics/numerical-modelling and another ten years of experience in civil engineering. His geomechanical expertise include creation of complex geomechanical models and seeking numerical solutions for problems such as mine stability, high stress issues, influence of mining method; Pit slope stability analyses; Geomechanical data processing; Sensitivity checks, sills and pillars design; etc. His civil engineering expertise include project planning and execution, construction and contract management, etc. He also served for United Nations as a civil engineer in several conflict regions around the world. Mr. Paudel has master's degree in computational mechanics from Ruhr University, Germany.
