Dr. Nerem joined the faculty in August 2000 after spending over 6 years at NASA/Goddard Space Flight Center as a geophysicist, and over 4 years at the University of Texas at Austin as an assistant and associate professor. He received his B.S. degree in Geology from Colorado State University in 1982, and his M.S. and Ph.D. degrees in Aerospace Engineering from The University in 1985 and 1989 respectively. Dr. Nerem also worked for NOAA and the Jet Propulsion Laboratory during his graduate training.
Dr. Nerem has more than 70 refereed journal articles and 13 refereed conference publications covering a variety of topics in satellite orbit determination, geophysics, oceanography, climate change, and planetary science. He has personally given more than 100 presentations at scientific conferences, in addition to co-authoring an equal number of presentations, and has chaired a dozen sessions at those conferences. In addition, he has co-authored a chapter for a book on the gravity field and co-edited a book on gravity field determination. He has served as an Associate Editor of the Journal of Geophysical Research - Solid Earth, and as Geodesy Editor for Eos Transactions of the American Geophysical Union (AGU). He also was awarded an Editors' Citation for Excellence in Refereeing by the journal Geophysical Research Letters in 1993. In 2002, he was elected to a 2-year term as Secretary of the Geodesy Section of the AGU. In 2005 he gave the honorary Bowie Lecture at the fall meeting of the American Geophysical Union. He received the AGU Geodesy Section Award in 2006. He was elected a Fellow of the AGU in 2008. He is a Lead Author of the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report (AR5), sea level change chapter.
Dr. Nerem is a specialist in satellite orbit determination, satellite remote sensing, and space geodesy, the latter dealing with measuring the Earth's shape, gravity field, and sea level using space-based techniques. He has also applied these techniques to measuring the gravity fields of Venus and Mars. Dr. Nerem has participated in several NASA flight projects including Lageos II, TOPEX/Poseidon, Jason-1, Pioneer Venus Orbiter, and Mars Observer. In 1995, Dr. Nerem was awarded NASA's Exceptional Scientific Achievement Medal for his research in the area of gravity field determination, in addition to a dozen NASA achievement and performance awards he received while at NASA. Dr. Nerem’s research is currently supported by the National Science Foundation, NASA, and NOAA.
Since arriving at CU, Dr. Nerem has taught graduate level classes in Space Flight Dynamics, Satellite Geodesy, Satellite Technology, and Engineering Data Analysis Methods, and undergraduate classes in orbital mechanics and senior projects. In the past he has taught courses on Remote Sensing from Space, Applications of the Global Positioning System, and Orbital Mechanics, both at the graduate and undergraduate levels. He is currently Associate Director of CU’s Colorado Center for Astrodynamics Research, and a Fellow of CU’s Cooperative Institute for Research in Environmental Sciences.

Prof. Holzinger began his faculty career in the Fall 2012 semester, and since has constructed a rigorous, externally funded, theory-to-hardware high-impact research program. His lab research draws from dynamics, controls, autonomy, and estimation disciplines, focusing on Space Situational Awareness, distributed spacecraft formation flight, proximity operations & rendezvous, and optimal reachability theory applications.
Prof. Holzinger is an Associate Professor, H. Joseph Smead Faculty Fellow, and Associate Chair for Graduate Studies in the Smead Aerospace Engineering Sciences Department at the University of Colorado Boulder. In this department he also serves as both the Associate Chair for Graduate Studies and the Associate Director for the Colorado Center for Astrodynamics Research (CCAR). His research focuses on theoretical and empirical aspects of space domain awareness, in which he has authored or co-authored over 100 conference and journal papers. Dr. Holzinger has made fundamental advances in low signal-to-noise ratio detection and tracking, telescope tasking to resolve hypotheses, lightcurve inversion, and reachability theory.
He joined Smead Aerospace in 2018 after six years on the Georgia Tech faculty, where he led construction of multiple Raven-Class Space Situational Awareness telescopes (GT- SORT), the Omnidirectional Space Situational Awareness (OmniSSA) Array, and served as Principal Investigator for an Air Force CubeSat program (RECONnaissance of Space Objects). Holzinger also previously worked at Northrop Grumman and Aerojet. In the summer of 2019 Prof. Holzinger hosted the AFRL Non-Resolvable SOI Workshop.
He is a recipient of an AFOSR Young Investigator Award and the National Academies Grainger Award, and is a National Academies selectee for the US Frontiers of Engineering Symposium. Dr. Holzinger is an AIAA Associate Fellow, an Associate Editor for IEEE Transactions in Aerospace and Electronic Systems, and is the Chair for the AAS Space Surveillance Technical Committee (AMOS Conference). Dr. Holzinger holds a PhD from the University of Colorado Boulder, and M.S. & B.S. degrees from the University of Washington.
