Douglas Lundholm
Researcher
Now at Uppsala University as a member of the group Analysis, PDEs and Applications.

Funded by a Swedish Research Council Junior Researcher Project Grant for the period 2014-2017/18 with my project "Spectral theory of quantum systems with exotic symmetries".
During the spring 2013 I was a CARMIN postdoc visiting:
IHÉS, January - April, 2013.
IHP, April - July, 2013, for the trimester program Variational and Spectral
Methods in Quantum Mechanics.
During the fall 2012 I was a postdoc at Institut Mittag-Leffler in the program Hamiltonians in Magnetic Fields.
During 2011-2012 I was an EPDI laureate visiting:
IHÉS, September - October, 2011.
FIM, ETH Zurich, November - December, 2011, and April - August, 2012.
