My research as a physicist has focused on producing innovations in fusion energy science. I am principally an experimentalist, but also do extensive computational work as it suits the topic. In my Ph.D. work at UCLA, I studied a new type of ion beam (composed of both positive and negative ions), as well as a means to accelerate such a beam and the physics of beam transport across a magnetic field:


As a post-doc in the ASDEX Upgrade (AUG) tokamak group in Garching, Germany, I worked in the mainstream of the international magnetic confinement fusion effort, and was responsible for operation and physics analysis of electron cyclotron emission (ECE) diagnostic data. With my colleagues, I integrated ECE into the real-time diagnostic loop for detection of neoclassical tearing modes (NTMs):


During a US Dept. of Energy Fusion Post-doc Fellowship at the University of Washington, I explored measurement of the interval magnetic field in the relatively low-field, high density HIT-SI spheromak plasma. A novel polarimeter diagnostic was designed:


I am continuing the polarimeter development here at UAA, as well as continuing to explore other fusion and plasma diagnostic topics and topics in RF plasma sheaths and ion beams. I focus on fusion energy because of its great potential to benefit society by providing clean, virtually limitless energy. In considering the ramification of transformative science like fusion, I have also developed an interest in studying energy policy scenarios that ensure that the advent of fusion energy occurs in a way that is truly beneficial to the peoples and natural environment of the world and is not exploitative or destructive.
