A Ph.D.-trained geospatial engineering expert with more than 45 years of experience, he focuses on land surveying, photogrammetry, geographic information systems (GIS), 3D modeling, laser scanning, remote sensing, topographic mapping, boundary surveying, earthwork quantities, title boundaries, slope failure analysis, inverse condemnation, wildland fire investigations, orthophotography, CAD, and animated fly-through visualization. He also has more than 25 years of expert witness experience providing consultations, deposition testimony, and courtroom testimony involving geospatial engineering, land surveying, mapping, and related technical issues.

His professional experience includes serving as Professor Emeritus, Professor, Associate Professor, Assistant Professor, Director of a Mapping Science Center of Excellence, Ontario Land Surveyor, Photogrammetrist, Geospatial Engineering Consultant, and Expert Witness within the public, academic, and private sectors. Throughout his career, he has led and supported projects involving land surveying, geospatial engineering, GIS, photogrammetry, GPS, highway design, 3D surface modeling, laser scanning, CAD systems, mapping, and surveying technologies. His consulting experience includes forensic analyses related to boundary disputes, wildfire and inverse condemnation matters, construction and earthwork evaluations, slope failures, laser scanning, mapping projects, and court-appointed surveying assignments. He has also developed surveying education programs, technical manuals, GIS applications, and mapping software supporting engineering and surveying practice.

He earned a Ph.D. in Image Processing, a Diploma in Engineering in Photogrammetry, a Master of Science in Remote Sensing, and a Bachelor of Science in Geography. He is licensed as a Professional Land Surveyor in California and Indiana and is also an Ontario Land Surveyor and a Member of the Royal Institution of Chartered Surveyors. His professional involvement includes leadership and reviewer roles with surveying, photogrammetry, GIS, and engineering organizations, as well as authorship of technical publications on geospatial engineering, surveying, visualization, and mapping technologies. He is a member of the National Society of Professional Land Surveyors and the Royal Institution of Chartered Surveyors.
