Research

Plasma Science and Fusion Center (PSFC), MIT 2016-Present
Graduate Advisor: Dr. Richard Temkin
Generation of short (ns), high-power (MW-GW) RF pulses in X-band and W-band in support of next-generation particle accelerator concepts. Recent work has included the development of a laser-driven semiconductor switch for generating nanosecond pulses from the 110 GHz Megawatt gyrotron. First observation of increased semiconductor reflection efficiency when operated at megawatt level RF power. Future work will include development of power extractors for two-beam wakefield accelerators, in collaboration with the Argonne Wakefield Accelerator at Argonne National Lab.

Eagle Harbor Technologies, Seattle, WA 2012-2016
Supervisors: Dr. Timothy Ziemba, Dr. Kenneth E. Miller
Worked as a research engineer to design cutting-edge pulsed power technology as part of a research team, funded under research grants from NASA, DOE, and DOD. Developed circuitry and fundamental circuit board geometries for custom high-power nanosecond pulse generators and plasma diagnostics. 

Advanced Propulsion Lab, University of Washington 2010-2011
Advisors: Dr. Robert Winglee, Dr. James Prager
Conducted experimental research into novel helicon plasma thruster designs, driving ‘whistler waves’ in inductively-coupled plasmas. Designed and constructed plasma diagnostic instruments, including B-Dot and Langmuir probes.
