Research Interests: I am interested in string theory and supergravity, their applications to other phenomena via holography, particle physics, cosmology and quantum field theory. String theory is a leading candidate for a theory of quantum gravity, and also provides a framework for the unification of the forces of nature. It has both "direct" applications, by which one can investigate questions about the evolution of the early Universe, the nature of...
Research Interests: My research is in the general area of space plasma physics, cosmic dust, and planetary science. My primary work takes place at the Institute for Modeling Plasmas, Atmospheres, and Cosmic DusT (IMPACT, http://impact.colorado.edu ), where we have several parallel experimental and modeling efforts related to plasma/surface interactions at airless bodies, the evolution of planetary surfaces, the dynamics of cosmic dust, the physics of hypervelocity impacts at small scales,...
