Brian Weaver, Ph.D. is an Assistant Professor (Senior Research) of Geomatics in the school of Civil and Construction Engineering at Oregon State University. He received his B.S. and M.S. degrees in Civil Engineering with an emphasis in Geomatics at Oregon State University, and Ph.D. degree in Civil Engineering with an emphasis on GNSS-based geodesy at the University of Nottingham. His research expertise includes development of satellite radar altimetry and GNSS data processing algorithms for high-accuracy applications and alignment of geodetic data to the national reference frame. Dr. Weaver has developed new techniques to enhance GNSS position accuracy and altimetry- based sea level estimation in challenging environments. His research outcomes have contributed toward new features in NOAA tools (i.e., OPUS and VDatum) that are used to align a variety of data sets to the national reference frame. He also gained experience working as a Civil Engineering and Surveying intern in both the public and private sectors, with projects focused on structural analysis/design, water/wastewater systems, roadway design, and paving. During his time at Oregon State University, and while employed as a Quality Assurance Technician at Trimble Geomatics, Dr. Weaver conducted surveys using a variety of instruments and technologies: analogue/digital levels, total stations, GNSS receivers, UAS, and lidar.
