Dorota A. Grejner-Brzezinska
Dr. Dorota A. Grejner-Brzezinska is the University Distinguished Professor, Lowber B. Strange Endowed Chair and Professor in the Department of Civil, Environmental and Geodetic Engineering, and serves as the Associate Dean for Research in the College of Engineering at The Ohio State University (OSU). She is also a Director of the Satellite Positioning and Inertial Navigation (SPIN) Laboratory.
Her research interests cover GPS/GNSS algorithms, GNSS/inertial and other sensor integration for navigation in GNSS-challenged environments, sensors and algorithms for indoor and personal navigation, image-based navigation using Artificial Intelligence (AI) methods, and mobile mapping. She published over 350 peer reviewed journal and proceedings papers, numerous technical reports and five book chapters on GPS and navigation, and led nearly 60 sponsored research projects with the total budget of over $22 million.
Dr. Brzezinska's research accomplishments are in three primary areas: (1) high-accuracy navigation and positioning algorithms and methods that include (a) design and development of novel algorithms and methods for high accuracy GPS and Low Earth Orbiters orbit estimation, and Earth Orientation Parameter estimation with GPS, (b) advanced positioning algorithms for cm-level GPS accuracy, such as the pioneering development and implementation of network-based real-time kinematic solution and Precise Point Positioning; (2) design and implementation of the high-accuracy algorithms and multi-sensor system prototypes for navigation in GPS-challenged environments, including GPS/INS, image-based navigation using AI methods, personal and collaborative navigation; (3) pioneering work in developing novel, fast and accurate algorithms that use ionospheric disturbance filtered from the GPS signals to detect and locate clandestine nuclear explosions and earthquakes.
Dr. Brzezinska is a member of the National Academy of Engineering (NAE), Fellow of the Institute of Navigation (ION), Fellow of the Royal Institute of Navigation (RIN), and the recipient of the 2016 ION Johannes Kepler Award, the 2005 ION Thomas Thurlow Award, the 2005 and 2015 United States Geospatial Information Foundation (USGIF) Academic Research Award, and the 2018 International Association of the Institutes of Navigation (IAIN) John Harrison Award. She served as President of the Institute of Navigation (2015-2017), and President of the International Association of Geodesy (IAG) Commission 4, Positioning and Applications (2011-2015), and is an IAG Fellow.
Dr. Brzezinska holds an M.S. and a Ph.D. in Geodetic Science from The Ohio State University, and an M.S. in Surveying Engineering and Land Management Systems from the University of Warmia and Mazury, Poland.
