Teaching: Space physics and plasma physics (grad level)
Teaching graduate -level space physics classes (Numerical simulations in fluid and plasma, etc.) at UAF.

Space plasma simulation is a subject which is in its infancy, but which is already having an important impact on space science. Its growth is being spurred onward by the continuing increase in capacity (speed and memory) of computers and by advances in the sophistication of numerical models. These advances are making it possible to simulate more realistic situations using more complex models. Already significant three-dimensional MHD calculations of the magnetosphere and its interaction with the solar wind have been carried out. In addition multi-dimensional particle simulations are illuminating many of the microscopic physics processes which go on (instabilities, saturation levels and wave nonlinearity, shock structure, etc.). Notwithstanding these advances, the surface has only been scratched; many challenges and opportunities are provided by simulation both for the space physicist and the model builders (also for computer designers). In MHD models more physics need to be included (Hall effect, gyroviscosity, accurate models of boundaries, how do we put microscopic physics effects into macroscopic codes, etc.). For model builders correct treatments of systems containing a large range of important space and time scales, magnetic field strengths, Alfven wave velocity, etc. present real challenges. What are the best ways to diagnose these complex models and obtain meaningful information? What quantities should be looked at? How should they be displayed? A discussion of the promises, the prospects, and the challenges of the above topics will be given with examples taken from recent work.

from space to laboratory plasma physics;
The Sun ejects plasma from its atmosphere into interplanetary space in a stream of material called the solar wind. The amount of interplanetary plasma can vary depending on the level of activity of the Sun. Typically, the solar system contains about 5 plasma particles per cubic centimeter near Earth, but this number drops off as you travel farther from the Sun.
With similar goals in mind, each of these missions increases our understanding of the chemical, molecular, and elemental composition of dust, as well as its distribution near planetary systems and within interplanetary space.

From the information collected, interplanetary dust is distributed very sparsely across the solar system and there is no known distribution for the dust. In other words, the amount of dust surrounding Saturn might be the same as the amount between the orbits of Jupiter and Saturn. We can also speculate that there are fewer particles around the Sun. Once the particles get too close to the Sun, the heat just melts them away.
Human Knowledge: Foundations and Limits
Scientists have been researching dust in the solar system for decades. Most of the more recent missions through the solar system have instruments attached to the outer portion of the spacecraft that analyze dust as they travel on their path through the solar system. The Cosmic-Dust-Analyzer, onboard the spacecraft, checked out the dust distribution en route to Saturn and Titan. The dust experiment mapped the distribution of dust as it orbited Jupiter in the mid-1990s. The Ulysses instrument continues to analyze dust as the spacecraft makes its second pass around the Sun. NASA's Stardust spacecraft, the first to encounter a comet, captured interplanetary dust particles and brought them back to Earth in 2006. Most recently, the Student Dust Counter (), engineered by students at the University of Colorado, is attached to the spacecraft measuring dust on its way to Pluto.
