Modeling the Ionosphere-Thermosphere

Joseph Huba is a Head Research Geophysicist of the Space Plasma Physics Division at the Naval Research Laboratory, Washington, D.C., USA. Huba's primary area of expertise is the stability of collisional and collisionless plasmas. In this regard he has performed a number of linear and nonlinear studies of a variety of kinetic and fluid plasma instabilities using both analytical and numerical techniques. Huba's research interests have included the study of the Rayleigh-Taylor instability, the Kelvin-Helmholtz instability, the nonlinear theory of interchange instabilities, plasma opening switch dynamics, dynamics of the solar atmosphere, wave phenomena in the ionospheres of earth and Venus, and non-ideal MHD dynamics (i.e., Hall MHD). His current research interests are modeling of the earth's ionosphere and plasmasphere. Huba has over 150 research publications in these areas. He is a Fellow of the American Physical Society. He is a member of the American Geophysical Union, the American Physical Society, and the International Union of Radio Science (URSI). Huba served as an associate editor for the Journal of Geophysical Research from 1983 to 1986. He was a member of the NSF CEDAR Science Steering Committee (2008-2010) and has served on a number of NSF and NASA panels.
