Research Interests
 The principle goal of my research through the years has been
to address questions left unanswered by the Standard Model. These
questions include understanding the hierarchy between the weak
scale and the Planck scale, the strong CP problem,
the origin of the
generation structure of quarks and leptons, as well as the quark
and lepton mass matrix, quantum general relativity and its
puzzles, and questions of early universe cosmology, such as the
origin of the asymmetry between matter and antimatter, the nature
of the dark matter, and the physics which underlies inflation.
I have made several important contributions to our thinking
about a number of these subjects, and, needless to say, have been
less successful in my attacks on others.

In attacking the
hierarchy problem, in collaboration with Fischler
and Srednicki, I was among the first to suggest that
supersymmetry might play an important role, and developed (in
collaborations) some of the first phenomenologically sensible
models of low energy supersymmetry. Subsequently, Affleck, Seiberg
and I were the first to exhibit models of dynamical
supersymmetry breaking, and to understand this phenomenon in a
general way. With Ann Nelson, Yossi Nir and my student Yuri Shirman,
I developed
the first realistic particle physics models with dynamical
supersymmetry breaking, in which ``GaugeMediated Supersymmetry
Breaking" plays a crucial role.
On the question of strong CP violation, Fischler, Srednicki
and I
proposed the ``Invisible Axion," still among the most plausible
solutions of this puzzle and the subject of active experimental
search. Fischler and I were among those who first appreciated the cosmological
constraints on the axion, and its possible role as a dark matter
particle. String theory has lead to a much more sophisticated
understanding of the invisible axion, both at a fundamental level
and in cosmology, I have devoted much effort in recent
years to this issue. I have also been interested in
the question of spontaneous CP violation as the
explanation of the small value of the $\theta$ parameter of QCD,
and again string theory and supersymmetry have helped shape our
understanding of these subjects.

From the start of the ``First String Revolution" in the mid
1980's, I have appreciated that string theory is a tool to
investigate the full set of questions of physics beyond the
Standard Model, and this has guided many of my investigations of the
subject. This
research deals with both fundamental issues
and issues of a more phenomenological character. In the past,
Rohm, Seiberg Witten and I discovered the ``gaugino
condensation" mechanism which lifts the degeneracy among many
string vacua. We elucidated the role of FayetIliopoulos Dterms
(with Seiberg and Witten) and of world sheet instantons (also with
Wen). In more recent years, I have explored
the phenomenology of the strongly coupled theory (with Banks), and
other issues.
I have throughout tried to formulate the problems of string
phenomenology in a generic way, with the hope of obtaining robust
predictions. In recent
years, I have outlined and pursued possible programs to
understand whether low energy supersymmetry might be a robust
prediction of string theory, and how one might obtain predictions
for the pattern of soft breakings. Recently, much of my research
in string theory has focussed on understanding the socalled
string theory landscape, and whether it predicts phenomena which
might be observed at the Large Hadron Collider.
