Research Experience:
Plasma Theory and Simulation Group, Electrical Engineering, UC Berkeley,
8/2001-Present -- Graduate Student Researcher --
The Plasma Theory and Simulation Group focuses on analytic and
computational modeling of plasma devices using first principle techniques.
Plasma resonances are investigated with the interest in developing
low-power high-density devices.
Using a wave coinciding with a natural mode of the system allows for
large-area reactors to be conceived.
Another topic of research is
the computational characterization of DC discharges for plasma processing
use.
The Particle-In-Cell (PIC) method with Monte Carlo collisions allows for a
fully kinetic characterization of DC discharge devices.

Computational Gas and Plasmadynamics Laboratory, Mechanical Engineering, Worcester Polytechnic Institute, 6/2000-8/2001 -- Graduate Student Researcher -- Work included developement of a finite volume Poisson solver on unstructured tetrahedral meshes and addition of degrees of freedom to a DSMC gasdynamics simulation program. The Poisson solver was merged with the program with additional modifcations to create a Vlasov-Poisson PIC code on unstructured meshes.
Teaching Experience:
Instructor, Part Time, Art Institute of California in
San Francisco, January 2006-present
-- Duties include teaching
undegraduates in the Visual and Game Programming department
the essentials of computer science. Courses taught include
Operating Systems and Shell Scripting (Winter 2006)
and Design Patterns and Data Structures (Spring 2006).
Graduate Student Instructor, c/o Professor Verboncoeur, UC Berkeley, Spring 2006, E170B: Introduction to Modeling and Simulation II -- Duties include designing and giving the lectures, designing homework assignments, teaching Matlab/octave fundamentals, and presenting engineering and computational sides of simulations.
Graduate Student Mentor, SUPERB program, c/o Professor Birdsall, UC Berkeley, Summer 2003 -- The SUPERB program invites graduates to participate in cross-disciplinary research under the advice of a professor and graduate student mentor.Graduate Student Instructor, c/o Professor Gustafson, UC Berkeley, 8/2001-12/2001, EE117: Electromagentics -- duties included the organization of discussion sections, laboratory supervision, solution preparation, and additional office hours to aid students. Two discussion sections were held per week in which new and supplementary material was presented to students. Laboratory experiments were demonstrated weekly in class.

Lab Experience:
Microfabrication Technology (UC Berkeley EE143 Lab), Fall 2002 --
Labwork
consisted of manufacturing and testing of a microelectronic chip.
Familiarity with technologies such as photoresists, lithography, wet
etching, and deposition was gained through use of the appropriate equipment.
Testing of the electronic and MEMS chip components was done through
four point probes.
NASA Glenn Research Center, Summer 1999 -- Worked as part of research efforts of WPI to characterize the performance of a pulsed plasma thruster using triple Langmuir probes in a large vacuum chamber. Duties included computer programming, technical writing and reporting, instrument calibration, and data analysis.
