Clement Argwings Ogaja (born January 1972) is a Kenyan-born author and research geodesist at the National Oceanic and Atmospheric Administration. ^[2] Previously, he was a professor of geomatics engineering at California State University, Fresno, having also worked at Geoscience Australia in Canberra. ^{[3] [4]}

Education and career

He earned his BSc (First Class) in Surveying (Geomatics) from the University of Nairobi in 1997, ^[5] before moving to Australia where he studied for a PhD at UNSW Sydney. ^{[6] [7]} He completed his PhD in 2002, ^{[1] [8]} working on structural health monitoring of engineering structures, such as suspension bridges and tall buildings, using global positioning system. ^[7]

After his PhD, Ogaja worked at Geoscience Australia before joining California State University, Fresno in 2007 as an assistant professor. ^{[5] [3] [9]} He also worked for GPS companies and wrote books and articles on GPS and geomatics engineering. ^{[2] [10] [11] [12]}
