About me 
I received my BSc in Engineering Physics at Colorado School of Mines in Golden (1975),
then moved to New York to do graduate work at SUNYStony Brook, where I received
a Ph.D. in physics in 1980. I did postdoctoral research at
Princeton University in New Jersey (198083),
NORDITA in Copenhagen and Helsinki University of Technology (198384),
then joined the Princeton physics faculty for four years (19831987).
Since 1987 I have been a professor
of physics at Northwestern University in Evanston, Illinois.

What I do 
Research: I study the physical world by combining mathematical analysis and observation
(generally with the help of experimentally inclined colleagues and students). I try to formulate and
apply concepts and principles (physical laws) to relate observations of physical phenomena, such as
superconductivity, to fundamental properties of matter and radiation. The laws of physics
(e.g. quantum mechanics) are expressed in mathematical equations, so in practice I try to formulate
physical questions as mathematical problems.
Teaching: I teach physics  both the fundamentals as well as developments in current research.
For me, teaching and research are entangled.

My field 
Theoretical Physics.
I started research in the nuclear theory group at Stony Brook investigating
matter under conditions thought to exist in the interiors of cold, dense
stars called neutron stars. My current research is in the field of condensed matter
physics. Theoretical condensed matter research involves the discovery of new
concepts related to the collective behavior of enormous numbers of atomic constituents,
combined with the application of statistical mechanics and quantum theory to describe the
behavior of macroscopic matter. This behavior is clearly revealed at low temperatures,
or in the presence of strong electromagnetic or acoustic radiation fields where
quantum effects are important. Matter under such conditions is described by quantum
field theory. I conduct theoretical studies of matter in which quantum effects are
manifest in the observable properties of matter.
