Theoretical
high energy physics. Professor Harms has most recently worked on the
quantum
description of microscopic black holes and their relation to extended
objects
such as strings and membranes. The theory of extended objects is
currently
the best candidate for a unified description of all of the known
forces.
The theory also predicts the presence of new forces, for example a
scalar
component of gravity (the dilaton), which have so far not been detected
by
experiment. To test the validity of string theory as a description of
physical
phenomena, Professor Harms and his colleagues have performed various
calculations
to predict the affect of a scalar component of gravity on
physically
measurable quantities. Other recent projects include the calculation of black
hole and naked singularity decay rates in large extra dimensions, brane
creation in warped spacetimes and the thermodynamics of branes produced in
large extra dimensions. Professor Harms
received
his doctoral degree from Florida State University.
