QMC Transition Workshop: 7-9 May, 2018

Deadline for applications for this workshop was March 30, 2018


This workshop will take place at SAMSI, Research Triangle Park, NC


The transition workshop for the QMC program is an opportunity for the active working groups in the program to exchange results and share their perspectives on common issues. This workshop is focused on recent research progress that has been made in connection with the many research areas spanned by the QMC program. Sessions of talks dedicated to each working group will feature presentations by active members. The workshop also seeks to facilitate planning for continuing collaborations on further research questions to extend beyond the period of the QMC program.
