Princeton University, Princeton, New Jersey:  Ph.D. (1998) Astrophysics

Biographical Sketch

After graduating with a B.S. in applied physics in 1991 from Columbia University, John C. Wright received his doctorate in astrophysics at Princeton University in 1998 under the supervision of Dr. C. K. Phillips for a thesis titled,  “FastWave Current Drive Modeling in Tokamaks.”  He then served a three year post doctoral position and one year as a staff scientist in the plasma physics group at the University of Wisconsin-Madison under Dr. Stewart Prager.  He worked on magnetohydrodynamic modeling with emphasis on current drive techniques within that fluid model.

He returned to radio frequency research with a position in the Plasma Science and Fusion Center at MIT in the theory group working with Drs. Paul Bonoli and Peter Catto.  Since arriving at MIT he has developed a parallel version of the TORIC code in collaboration with E. D´Azevedo at Oak Ridge National Lab under the RF SciDAC initiative.  He present work at the PSFC focuses on applying advanced parallel RF models to experimental and theoretical RF issues.  Close on-going collaborations with the RF group on Alcator C-Mod have a direct impact on the direction of the experimental program. 

He continues to be involved in several international and multi-institutional domestic collaborations focusing on various modeling integration and algorithm development issues in RF modeling.
