Dr. Jokipii's research concerns many areas primarily related to the transport and acceleration of cosmic rays and energetic particles in the solar wind and in the galaxy. Major current thrusts revolve around work on the Ulysses and ACE space missions, for which he and his group are guest investigators, specializing in theoretical interpretaion and modelling of the observations. Specifically, Dr. Jokipii's group is currently in the midst of an extensive program of theoretical research to determine the transport coefficients of energetic particles in irregular (turbulent) plasmas and magnetic fields, avoiding the approximations used previously. This involves three-dimensional simulations, which are exceedingly demanding of computer resources. Initial results have already been published verifying that much older work must be redone in large part because one of the key assumptions made in this earlier work made a major part of the work completely spurious.
