Global carbon cycle, data assimilation, mathematical modeling, and remote sensing.
Dr. Brad Weir joined USRA in 2013 to work on the assimilation of satellite-based observations of trace gasses into the GEOS-5 model. He received his B.A. from New York University and his Ph.D. from the University of Arizona, both of which were in mathematics. His doctoral research, advised by Prof. Juan M. Restrepo, focused on modeling the interaction of waves and currents in the near-shore ocean. Following that, he took a postdoctoral position at the College of Earth, Ocean, and Atmospheric Sciences at Oregon State University. There, he helped develop a modern particle filter technique and used it to estimate the parameters of a marine biogeochemical model based on remote and in situ observations. This was part of a collaborative effort with Profs. Robert N. Miller and Yvette H. Spitz (at Oregon State) and Prof. Alexandre J. Chorin and Dr. Matthias Morzfeld (at Lawrence Berkeley National Laboratory).
