My research follows several lines of study, including fluctuation measurements in plasmas, the relationship of turbulent quantities to cross-field plasma transport, and the microphysics of dust impacts which drive the dusty plasma equilibria.
My diagnostic work on larger devices consists of data analysis and velocimetry analysis from a number of tokamak diagnostic instruments. This work is performed in collaboration with PPPL (NSTX), UC Davis (microwave imaging diagnostics for ASDEX, DIII-D, and KSTAR), POSTECH, and the FOM Institute. Of particular interest is the relationship between measured velocities and momentum transport, and much of this work is done in the context of the DOE Center for Momentum Transport and Flow Organization (CMTFO). I have two local experiments, the first of which is the Colorado FRC Experiment, located in the Duane physics building at CU. This is a merged spheromak device, with the primary objective of exploring the effect of driven and spontaneous flows in FRC's and spheromaks, and their relationship to fluctuations and macroscopic stability. I am also the deputy director of the Colorado Center for Lunar Dust and Atmospheric Studies, one of seven centers within the NASA Lunar Science Institute. The program of our center is the experimental and theoretical investigation of the lunar surface, including dusty plasma and impact processes, the origins of the lunar atmosphere, and the development of new instrument concepts. The centerpiece experimental facility is a 3 MV hypervelocity micrometeoroid accelerator (now under construction), to be capable of accelerating micron-sized particles up to 10's of km/s into a simulated lunar environment.
