Tim Collins received his bachelor’s degree in Physics from Oberlin College in 1990. He earned his MA (1992) and Ph.D. (1997) at the University of Rochester. His thesis was supervised by Professors Hugh M. Van Horn and H. Lawrence Helfer, on the topic of accretion disks surrounding white-dwarf stars in cataclysmic variable (CV) binary star systems. In addition to work on CV’s, his research has included investigation of neutron star oscillations, supernova 1987A, equation-of-state modeling for inertial confinement fusion (ICF), shock propagation in DT-saturated foams, beam-smoothing requirements for ICF, MJ-class ICF target design for laser-direct drive, and fast-electron preheat. His work currently focuses on OMEGA experiments, particularly signatures of mix in cryogenic implosions backlit with OMEGA EP, and planar mix experiments (warm and cryogenic). He serves as the Project Leader for DRACO, the University of Rochester’s 2-D arbitrary Lagrangian– Eulerian radiation–hydrodynamics simulation code.
