Simon Catterall is a Professor of Physics at
Syracuse University. He was born in England in 1964 and obtained
a BA in Physics from Oxford University in 1985. In 1989 he received
a D.Phil. in Theoretical Physics from Oxford. Following research
appointments at Cambridge University, University of Illinois and
the European Centre for Particle Physics (CERN) in Geneva, he joined
the faculty at Syracuse in 1994.
Prof. Catterall is currently interested in theoretical and computational
lattice studies of theories which attempt to go beyond the Standard Model
of particle physics.
In the past he has worked on discrete
theories of quantum gravity and string theory but more recently has been
interested in studying supersymmetric theories on the lattice. He has
developed new lattice formulations which allow an element of supersymmetry
to be preserved exactly at non-zero lattice spacing and has begun
studying these theories using Monte Carlo simulation.
Such studies can potentially cast light on conjectured dualities between
supersymmetric gauge theories and gravity and have impact and
application in string and M-theory.
He has also pioneered investigations of lattice gauge theories with
fermions in higher dimensional representations which may be
important for constructing technicolor models of
composite Higgs. Such models
are conjectured to develop conformally invariant phases as the number of
fermion flavors is increased. Close to these points the theory exhibits
a slow evolution of the coupling with energy scale -- the theory walks.
We have been examining the minimal model with 2 colors and 2 flavors
which can form the basis of a technicolor model for breaking the
electroweak theory with a light composite Higgs.
He has also recently begun a study of the role of four fermion interactions
in such theories. This work may have consequences for LHC physics.
Prof. Catterall is a member of the Scientific Program
Committee of USQCD - a collaboration of US scientists who
use large scale supercomputer simulation to study the nature and
interactions of elementary particles. This collaboration has dedicated
multi Teraflop scale supersomputers at Fermilab, Brookhaven
and Jlab for carrying
out these studies.

Simon has been
involved with integrating computers into the classroom.
As part of this he and his colaborators developed an internet-based multimedia
Mind and Machine.
He also helped develop a SimScience website devoted to explaining
how computer simulations are used in science. The latter two projects
received NSF support. Simon also regularly teaches courses on
employing python and
Java-based programming labs
He has also taught
Family and hobbies
Outside the classroom Simon is a keen rockclimber
and mountaineer being past President of the Oxford University
Mountaineering Club. He has climbed extensively both in Britain,
the United States, South America and the European Alps. See some slides
from a recent trip to the Cordillera Vilcanota in southern Peru.
Simon is married with two children and lives in Ithaca.
