Welcome to Robert Budny's home page (https://w3.pppl.gov/~budny)
I received a B.S in Mathematics from Massachusetts Institute
of Technology,
a Certificat du Trisieme Cycle in Mathametical Physics from the Universite du Paris,
and a Ph.D in Theortical Particle Physics from the University of Maryland
After active duty in the US Navy I was a Royal Society Fellow in the Department
of Theoretical Physics of Oxford University,
a Post-doctoral fellow in Physics at Stanford University,
and in Theoretical Physics at the Rockefeller University,
I joined Princeton University as a Physics Instructor teaching
Physics 101 and 102 "Physics for Poets"
Tokamak and ITER Division
of Princeton University's
Princeton Plasma Physics Laboratory
The Princeton University home page is
www.princeton.edu
The Princeton Plasma Laboratory home page is

I conduct research developing controlled thermonuclear fusion in
Tokamaks as a potential energy source
Much of my current research uses the TRANSP plasma analysis
code and the GS2 and GYRO gyrokinetic microturbulence codes
The TRANSP homepage is
w3.pppl.gov/transp
The GS2 homepage is
gs2.sourceforge.net
The GYRO homepage is
http://fusion.gat.com/comp/parallel/gyro.html
I have also been applying these codes to understand transport in
JET, DIII-D, and JT-60U plasmas.

Previously I collaborated on experiments in TFTR
