[|Niklas Beisert]
is a group leader at the Max-Planck-Institut für Gravitationsphysik, Potsdam. He is interested in symmetries and integrability in gauge and string theories.

Zvi Bern
is a member of the Physics Department at UCLA. His current primary interest is in developing new methods for calculating and understanding scattering amplitudes. He is especially interested in applications to LHC physics and to maximally supersymmetric gauge and gravity theories. To get an overview of his research you can watch this video: http://www.youtube.com/watch?v=3SYW6eZFHwU. His Erdos number is 3.

**John Joseph M. Carrasco**
is a postdoc at the Stanford Institute for Theoretical Physics. He likes gauge and gravity theories, and would like to better understand aspects of both.

**Einan Gardi**
is a lecturer in the School of Physics and Astronomy at the University of Edinburgh. His present research focuses on the infrared singularity structure of scattering amplitudes and on their factorization and exponentiation properties. He is also interested in the applications to LHC physics.

**Michael Gary**
is a graduate student at UCSB and will be moving to the Institute for Theoretical Physics at Vienna University of Technology in the fall. His research focuses on the interplay between locality and unitarity in quantum gravity. Of relevance to this program, he is interested in understanding bulk unitarity in AdS/CFT as well as recent developments relating amplitudes to polylogarithms.

[|Thomas Gehrmann]
is professor of theoretical physics at the University of Zurich, Switzerland. His research focuses on particle physics at high energy colliders, ranging from multi-loop calculations of scattering amplitudes to their implementation into event generator programs and comparison to collider data.

is on the UCSB faculty. His interests range from foundational issues in quantum gravity, to cosmology, to LHC physics. Of relevance to this program, he has been investigating aspects of the gravitational S-matrix in the high-energy limit, such as unitarity, finiteness, analyticity, and the relation to perturbative amplitudes. He has particular interest in the question of whether special properties of the loop amplitudes of (super)gravity may provide hints about the theoretical structure relevant to this regime, and about complementary insights directly from study of this regime.
