Division Leader for Earth and Environmental Sciences at Los Alamos National Laboratory.
Dr. Bossert provides leadership and management to 200 technical and support staff, and manages and develops a diverse array of geosciences programs. Dr. Bossert has been at Los Alamos for 27 years and served in a variety of research and technical management capacities. For the past eight years, he has also served as the Program Manager for LANL’s Climate Research portfolio of $27M to the Climate and Environmental Sciences Division of the DOE’s Office of Science.
Dr. Bossert’s technical background includes the measurement, analysis and modeling of flow and dispersion in mountainous and urban terrain, regional climate simulation, and wildfire behavior modeling. He received his Ph.D. in the Atmospheric Sciences from Colorado State University, and his B.S. from the University of California at Davis. He has authored or co-­‐ authored over 50 journal and other publications.
