Harmen J. Keyser, P.Geol., President
Harmen is a geologist and helicopter pilot with more than 30 years of experience in helicopter operations and mineral exploration around the world. In addition to geological expertise in a wide variety of deposit models and geological environments, he has flown various types of helicopters in a diverse variety of commercial, exploration and geophysical applications. It is this unique combination of experience as a geologist and helicopter pilot that inspired him to develop simpler and more efficient geophysical survey methods. He obtained a Bachelor of Science degree in Geology from Saint Mary's University in 1981.
Jenny Poon, B.Sc., GIT, Geophysicist
Jenny is a graduate of the University of Calgary geophysics program. She is skilled at airborne survey design, data collection, data processing, reporting, and QA/QC procedures using advanced software in complex geophysical environments.
Jounada Oueity, Ph.D., Geophysicist
Jounada has a B.Sc. in geophysics from the University of Damascus, an M.Sc. in geophysics from the University of Texas at El Paso, and a Ph.D. in geophysics from the University of British Columbia. His thesis work focused on the heterogeneous nature of the lower crust and upper mantle based on crustal scale geophysical data, as well as more shallow structural studies using gravity and aeromagnetic data. He has experience with forward modeling and advanced image enhancement techniques using curvelets to increase signal to noise ratios. His work at Precision involves routine data processing as well as advanced geophysical interpretations using various noise reduction and inversion methods.
Shawn D. Walker, M.Sc., GIT
Shawn graduated from the University of Alberta with a B.Sc. in geology and a M.Sc. in geophysics. His thesis work investigated the magnetic properties of various rocks from Canada and Siberia, and he is a specialist in the determination of shear zones from aeromagnetic data. He has worked across northern Canada and Alaska in ground and airborne geophysical applications in a wide variety of geological environments and mineral deposit styles. Shawn enjoys working for Precision as a helicopter system operator in addition to applying his skills in geophysical data processing and interpretations.
Dak Darbha, M.Sc., Geophysicist
Dak is a graduate of the University of Western Ontario with a M.Sc. degree in geophysics. He is a consulting geophysicist with 40 years' experience in airborne geophysics for mineral exploration and scientific applications on a worldwide basis. He is highly skilled in magnetic, electromagnetic, radiometric, and gravity survey design and implementation, software development, system design and testing, data processing, and advanced interpretation. Precision actively uses Dak's professional services to maximize value in airborne geophysics.
