Callum A Walter, PhD
Callum is a Research Geologist with the Geology, Minerals, Energy, and Geophysics Science Center in Moffett Field, CA. He is currently specializing in applied geophysics and mineral exploration supporting the USGS’s Earth Mapping Resources Initiative (EMRI) for the detection of critical minerals vital to the United States economy and national security.
Callum is a geophysicist broadly interested in advancing potential field geophysical surveying techniques (autonomous and adaptive sensing) that aid in the characterization of critical mineral resources. He specializes in combining geologic mapping, geophysical surveying, remote sensing, and spatial analysis to detect and assess buried resource occurrences at depth. Presently, his research focuses on advancing geophysical surveying and processing techniques for the detection and characterization of critical mineral deposits on Earth. Callum is also interested in how geophysical surveying and remote sensing can inform in-situ resource utilization (ISRU) on our celestial neighbors in partnership with NASA colleagues.
