Research Interests
Multiscale simulation of material behavior including plasticity and fracture. Various aspects of nanomechanics including dynamical simulation of sub-micron scale MEMS (micromachines) and mechanical properties of biological membranes. Concurrent multiscale methodology development including hybrid atomistic/continuum algorithms (MD/FEM) for coupling length scales and effective models of multiscale systems (CGMD). Unconventional superconductivity (Single Spin Superconductivity).
Personal Background
Robert Rudd has been a staff physicist in the Metals and Alloys Group since April 2000, using atomistic and multiscale computer simulation to study mechanics at the nanoscale. He received his BS degree from the University of Virginia in 1987 and his PhD degree in Theoretical Physics from Princeton University 1992. His graduate advisor was Prof. David J. Gross and his thesis topic entitled "Light-Cone Gauge Quantization of String Theories with Dilatons" showed how a special gauge could be employed to calculate properties of string theories relevant to cosmology and quantum gravity. In particular, it was shown that a class of generalized, large-amplitude gravitational waves are exact solutions of the full non-linear string theory. Also it was shown how the special states of two-dimensional quantum gravity appear in the light-cone gauge. Dr. Rudd then spent three years in the String Theory group at Rutgers University (1992-1995) as a Postdoctoral Fellow, where he developed the formulation of gauge theories as string theory with special emphasis on non-perturbative effects. He then joined the Complex Systems Theory Branch as an SFA contractor, returning to his roots in Condensed Matter theory in collaborations with Dr. Warren Pickett and Dr. Jeremy Broughton. In 1998 he became a Lecturer in the Department of Materials at the University of Oxford and a Fellow of Linacre College. The focus of his work at NRL and Oxford, and now at LLNL, has been the simulation of multiscale systems. Dr. Rudd is a former director of the LLNL Summer Institute on Computational Materials Science and Chemistry, a two-month summer school and mentorship program for graduate students at LLNL. He is an editor (with A.P. Sutton) of the Oxford Series on Materials Modelling, a series of books published by Oxford University Press. He is also on the editorial board of the journals Molecular Simulation and Modelling and Simulation in Materials Science and Engineering.
