The Team

Paul Althaus, Dr.-Ing., Dipl.-Geophys.

Managing Director

Paul has more than 30 years of experience in geophysics and management of teams and companies. He became chairman of the board of DMT Geosciences 10 years ago and took on the role of Managing Director in 2020.
He has a broad background in geophysics. He wrote his diploma in Germany on near surface seismic, while his PhD research focused on capacitive and inductive resistivity. Paul is an expert in vibration monitoring and mitigation. He has been responsible for geophysical instrument development, and initiated DMT’s geo-monitoring solution.


Consultant Emeritus
Jim Henderson has in excess of 45 years of project management and consulting experience in geophysics. Following graduation from the University of Toronto, he joined Northern Engineering as a project geophysicist managing field programs which involved the use of state-of-the-art geophysical applications to map permafrost distribution in remote areas. Dr. Henderson has played a pivotal role in pioneering the application of geophysics for surface mineable and in-situ oil sands exploration and development.

He joined Hardy Associates in 1977 as an engineering geophysicist where he was responsible for the project management of a wide range of geophysical applications. In 1979 he participated in the formation of Geo-Physi-Con Co. Ltd. and was Vice-President, later promoted to President. His responsibilities included technical direction as well as marketing and administration. In 1993 he joined AMCL as the Manager of Geophysical Services with the special responsibility of establishing a geophysical group to service the resource sector. While at AMCL/DMT he successfully completed his M.E. Des. and PhD. He is currently a technical advisor for DMT.


Sam Chen, as part of the management team, is responsible for Finance and Accounting, Human Resources, Health & Safety, Insurance and IT, and serves as an officer of the company. He also serves as CFO overseeing finance and HR for TMN Inc., a sister company.

Sam has 17 years of progressive experience in finance and accounting. His experience has involved general corporate accounting, reporting, costing, forecast and planning, taxation and financial audits in the oil gas, mining and IT industry. He is also involved in admin/HR supporting functions. Before he switched his career to finance and accounting, he had experience in software programming and technical support in IT and the telecommunication industry. Sam has a bachelor degree in computer science , an MBA from York University obtained in 2003, and a Professional Accounting designation completed in 2006. In addition he completed a CPA in-depth tax program in 2019.


Senior Geophysicist
Robert has a variety of experience with a variety of geophysical methods including seismic refraction, seismic reflection, marine seismic, ground penetrating radar, electrical resistivity imaging, and EM methods. His experience includes designing, conducting, and interpreting geophysical programs. Projects on which he has been involved include marine geophysical surveys, oil and gas exploration, fracture mapping and seismic anisotropy analysis, using near surface geophysics for risk analysis in mine operations, diamond exploration, gold/copper exploration, mapping depth to bedrock and rippability of bedrock for pipelines and facility locations, stratigraphy mapping for horizontal directional drilling, grounding design investigations, and environmental investigations for facility decommissioning.

Robert has an M.Sc. in geophysics from the University of Calgary and is currently working on his Ph.D.


Senior Geophysicist
Jane has extensive experience processing and interpreting many types of geophysical data. She has been involved with a wide variety of projects, including identifying and mapping aquifer facies with GPR, designing and building a borehole probe for measuring magnetic susceptibility, inverting and interpreting airborne EM data, and processing and interpreting marine seismic surveys. Recently she has been working on multi-survey interpretations and in the inversion of airborne and ground TEM data using the UBC GIF inversion code. Jane has a BSc (Engineering Physics) and MSc (Engineering) from Queen’s University, and a PhD in Geophysics from the University of British Columbia.


Adam completed his BSc. in Geophysics from the University of Calgary in 2008. Adam brought significant work experience with seismic geophysical software to DMT Geosciences Ltd. when he joined in 2010. Now his expertise also includes acquisition, processing and interpretation of Electrical Resistivity Imaging (ERI), capacitively coupled resistivity (OhmMapper), fixed frequency electromagnetic methods (e.g. EM31), seismic methods and Ground Penetrating Radar (GPR) among others. He has applied these methods in remediation and reclamation environmental applications, permafrost mapping, bedrock characterization, groundwater detection, and near surface gravel/sand resource identification.

Adam also enjoys leading a healthy lifestyle including activities such as hiking and golfing.


Drew obtained a B.Sc. in Geophysics from the University of Calgary in 2010. Drew is an expert in conducting and processing time domain electromagnetic (TEM) surveys. Since joining DMT in 2011 Drew has been undertaking seismic and TEM surveys for mapping stratigraphy as part of risk and water management investigations at oil sands mine sites. He is also familiar with data acquisition, processing and interpretation of fixed frequency electromagnetic (EM31 & EM38), magnetics, ground penetrating radar (GPR), capacitively-coupled resistivity and electrical resistivity (ERI) as part of geo-technical and environmental geophysical surveys.

A cool fact about Drew is that he enjoys archery and other target sports.


Patrick has been with DMT since 2011. He has extensive experience with the application of geophysics to numerous engineering, environmental, and exploration projects.  He is responsible for business development within the geophysics division in Alberta specifically in the application of geophysics to geotechnical engineering and environmental projects.

Patrick’s expertise lies the application of geophysics for roadways, pipeline crossings, delineation of saline contaminants, and vibration monitoring.  

Ian Grundy – BSc.

Geophysicist in Training
Ian graduated from the University of Victoria in 2019 and has since been working with DMT Geosciences. Ian has gained experience in a variety of geophysical methods through his involvement in multiple projects ranging from data collection to report preparation.

In his spare time, Ian enjoys exploring B.C’s Coast Mountain range


Geophysicist in Training
Mike recently finished his M.Sc. in Geology and Geophysics at the University of Calgary, where he also completed his B.Sc. in Geophysics. Mike has various experience in TEM surveys, electrical resistivity imaging (ERI), and seismic reflection interpretation, with additional exposure to geochemical methods in marine science environments. His focus is primarily on the near-surface environment using hydrogeology, geotechnical, and geophysical information to apply an inter-disciplinary approach to solve problems in geoscience, using his unique exposure to a variety of geoscience disciplines.

Mike spends most of his time-off playing in the mountains skiing, climbing, and biking.
