Hui Li - Astrophysics and Cosmology

Hui Li

Ph.D. in Astrophysics, Rice University, 1995

Director’s and Oppenheimer Postdoc Fellowships, LANL, 1995-2000

Fellow of American Physical Society, 2005

Research Interests: Plasma Astrophysics, High-Energy Astrophysics, Protoplanetary Disks and Protoplanets.

Chris Fryer - Astrophysics and Cosmology

Chris Fryer

Chris Fryer has worked on a wide variety of physics and astrophysics projects. His primary astrophysics studies include the engines, progenitors and emission from core-collapse supernovae and gamma-ray bursts, neutron star formation and populations, and chemical evolution and nucleosynthesis. For his work on core-collapse supernovae, he was named an APS fellow. He has also worked extensively in laboratory astrophysics studying turbulence, radiation transport, radiation hydrodynamics and atomic opacities. For his combined astrophysics and laboratory physics work, he was named a LANL fellow.

Keeley Costigan - Earth Systems

Keeley Costigan

Keeley Costigan has a broad background in atmospheric science, with more than 30 years of experience with atmospheric numerical models. Keeley’s research activities have included studies of atmospheric boundary layer and complex terrain meteorology, regional water cycles, Large Eddy Simulations (LES), and atmospheric transport and dispersion. She has modeled greenhouse gas and contaminant emissions, transport, and mixing, to aid in the interpretation of measurements in the Four Corners region and other urban and rural locations. Keeley has also simulated Electromagnetic Pulse (EMP) and analyzed both modeled and observed EMP signals for ground-based measurement systems, under varied environmental conditions.

David Coblentz - Geophysics

David Coblentz

Ph.D., Arizona - Geophysics, 1994

David Coblentz is the EES-17 (Geophysics) Group Leader in the Earth and Environmental Sciences Division. His academic background is in the field of numerical geodynamics and he is active in the application of solid earth geophysics and geodynamics to Earth Science problems relevant to the LANL mission. He is the author of more than 50 peer-reviewed publications in the field of intraplate stress modeling and the dynamics of the Earth's lithosphere. His recent work is focused on the in-situ stress field within reservoirs and terrain analysis using machine learning techniques.

Geoffrey Reeves - Space Physics

Geoffrey Reeves

Geoffrey Reeves came to Los Alamos National Lab in 1989 as a Directors post-doctoral fellow and has served as a technical researcher, group leader, project leader, program manager, and Laboratory Fellow. His research specialty is the physics of the space environment and the hazardous conditions in space posed by extreme natural and man-made events. Natural events, known as Space Weather, are produced by high rates of energy transfer from the sun into the near-Earth space environment. Man-made events include the production of long-lived radiation from high altitude nuclear explosions. Dr. Reeves has published over 500 papers on these and other topics in journals including Science, Nature, Space Weather, and the Journal of Geophysical Research. He is a member of several organizations including the American Geophysical Union, COSPAR, the American Physical Society, and the American Meteorological Society.
