He has been the lead investigator and/or designer for numerous project teams for mining companies and provides review and senior evaluation and counseling to a number of mining companies, research establishments, professional associations and provincial, state and federal agencies. Dr. Robertson participates on numerous technical review boards for mining companies and regulatory authorities. He has published extensively, participated in the drafting of numerous technical guides currently used by industry and regulatory bodies alike, and has been the recipient of a number of technical and industry awards.

Dr. Christoph Wels has a B.Sc. in Hydrology, a M.Sc. in Watershed Ecosystem Studies and a Ph.D. in Hydrogeology with over 15 years of professional experience in academic research and consulting. He has published several scientific papers in the areas of contaminant hydrogeology and watershed hydrology. Dr. Wels is Principal and Senior Hydrogeologist with Robertson GeoConsultants Inc. and specializes on groundwater modeling and evaluating the impact of mining projects on groundwater resources. He joined Robertson GeoConsultants in 1995 and has since been consulting to the mining and environmental industry in the areas of:

As senior hydrogeologist of RGC, he is responsible for all aspects of hydrogeological investigations from field work to detailed groundwater flow and transport modeling. His fluency in English, Spanish and German allows direct communication with clients and regulatory agencies all over the world.

 

Jack Caldwell, P.Eng, has a B.Sc. in Civil Engineering, an M.Sc. (Eng.) in Geotechnical Engineering and a post-graduate law degree. He has over 35 years engineering experience on mining, civil, geotechnical and site remediation projects. He has worked on numerous projects throughout southern Africa, Europe, Canada and the United States. His project experience includes:

In addition, Mr. Caldwell has been the lead specialist for various geotechnical and civil engineering projects in Southern California. Mr. Caldwell has written many engineering reports, proposals, and technical papers. He is the lead author of the book, Principles and Practice of Waste Encapsulation, on the design of waste disposal facilities for radioactive and hazardous wastes.

Ms. Olga Martychina has a M.Sc. in Cartography and over 17 years of professional experience in the Geomatics Industry. She has a wide range of experience in Project Management, GIS and Digital Mapping Technologies. She directed and coordinated all aspects of spatial projects, including:

  • the design and execution of workflow procedures
  • the creation of spatial/attributes data and products
  • the development and application of quality control procedures.
She has advanced knowledge of ESRI, CAD and other Spatial Data handling software modules. Additionally, Olga received The Intergraph Golden Mouse Award in Mapping Sciences for the 1:2,000,000 scale shaded relief map of the Province of BC, Canada in 1998. Olga recently joined Robertson GeoConsultants Inc. and will be responsible for the management and implementation of Mapping production activities, GIS analysis and database management.

Dr. Paul Ferguson has a B.Sc. in Geology and a Ph.D. in Geochemistry with 7 years of professional experience in academic research and consulting. He has published several scientific papers in the areas of aqueous and isotope geochemistry and presented at numerous international conferences. Dr. Ferguson is the Senior Geochemist at Robertson GeoConsultants Inc. and specializes in evaluating the impact of mining on local groundwater resources. He joined Robertson GeoConsultants in 2008 and has been a consultant to the mining and environmental industry in the areas of:

Mr. Lawrence Charlebois holds a B.Sc. in Geological-Environmental Engineering and a M.A.Sc. in Mining Engineering.  Mr. Charlebois is an Engineer-In-Training in the province of British Columbia with 4 years of environmental and mine waste project experience. Lawrence has diverse experience in environmental, hydrogeological, and geotechnical site investigations in a variety of climates and geologic settings.  His research background concerns the rheology (flow behaviour) of mine tailings and tailings deposit formation processes. Recently, Mr. Charlebois has been active in field and laboratory investigations concerning the atmospheric drying of thickened mine tailings.
Lawrence has been a geological engineer with Robertson GeoConsultants since 2009.
 

Bernard Brixel holds a B.Sc. in Geology, a M.Sc. in Hydrogeology, and has over two years of professional experience in consulting. Since joining RGC in 2010, he has been involved in a number of mining and environmental projects, including (i) contaminant plume characterization studies, (ii) seepage interception system design and (iii) tailings water balance.

His experience includes drilling/well construction programs oversight, hydraulic testing, numerical modeling and data reviews. His fluency in English, Spanish and French allows him to directly communicate and work with clients internationally.

Fergus Murphy graduated from Trinity College Dublin with a B.Sc. in Civil Engineering and completed his M.Sc. in Civil Engineering from in 2010. Mr. Murphy is a registered Engineer In Training with the Association of Professional Engineers and Geologists of British Columbia (APEGBC). Fergus joined Robertson GeoConsultants in 2011 and since then has worked closely with RGC’s research in the Oil Sands having spent two field seasons investigating the geotechnical and water balance characteristics of flocculated tailings. The scope of this work extends from field and laboratory work, through to data analysis and reporting.

 

Alexander Trapp holds a B.Eng. in Civil Engineering and a M.Sc in Water Resource Engineering and Management. Upon completing his graduate studies in April 2012 he joined Roberton GeoConsulants Inc. as a water resource engineer. Since joining the company he has been consulting in the areas of tailings water balance, tailings seepage studies and mine dewatering.

Alexander has experience in numerical groundwater and consolidation modeling, hydraulic testing and supervision of drilling programs.
