Brief Biography

Callum Walter completed a B.Sc.E. degree in geological engineering at Queen’s University with a special focus on applied geophysics. In 2016, he started a M.A.Sc. in applied geophysics at Queen’s University working with Dr. Alexander Braun and Dr. Georgia Fotopoulos, and was upgraded to the PhD program in September 2017. His thesis investigated how to reliably integrate an unmanned aerial vehicle (UAV) with a high-resolution optically pumped magnetometer for enhancing magnetic data collection in the mineral exploration industry. In addition, he completed a MITACs internship within this thesis, working alongside Sumac Geomatics Inc. in Thunder Bay, Ontario, Canada. This collaboration resulted in the successful integration of a UAV-magnetometry system and the reliable collection of UAV-borne magnetic data. This survey proved the feasibility and performance of the UAS-borne magnetic system with 99% of the data meeting industry standards.
