from Mainz University, visiting KITP from April 3 - April 22.
Working on scattering amplitudes and Wilson loops in N=4 sYM and QCD.

Rachel Karpman

is a mathematician, currently working at the Ohio State University. She is interested in positive Grassmannians and related combinatorics, and will be visiting April 17-26.

Kasia Krajewska

is at the Institute of Theoretical Physics, University of Warsaw, Poland, working on strong-field QED processes.

Florian Loebbert

from Humboldt University Berlin; visiting KITP from April 3 to May 26.
interested in symmetry structures in particle physics, in particular integrability in AdS/CFT.

Bernhard Mistlberger

from CERN. Visiting KITP from April 3 to April 22.
Working on N=4 SYM scattering amplitudes, multi-loop computation, QCD and collider phenomenology with an emphasis on Higgs boson physics.

Dian Peng

is at the University of Nebraska-Lincoln, a graduate student of Professor Starace's group.

Liang-You Peng

is from the School of Physics, Peking University, Beijing, China. His research interest focuses on dynamics of few-electron atomic and molecular systems, triggered and/or probed by attosecond and/or femtosecond pulses. Research Group Website: http://www.phy.pku.edu.cn/~lypeng/index_en.html

Hugh Thomas

is a mathematician at the Université du Québec à Montréal, who is interested in cluster algebras and Grassmannians, among other things. He is working with Nima Arkani-Hamed and Jaroslav Trnka on a project to understand the amplituhedron better.

Jaroslav Trnka

works at the Center of Quantum Mathematics and Physics (QMAP) of University of California, Davis, interested in new mathematical structures in scattering amplitudes such as the connection to positive Grassmannian, Amplituhedron in planar N=4 SYM and their extension to other cases.
