Dates: April 28 - 30, 2021

Location: PCS video conference

Coordinator: Jung-Wan Ryu (PCS IBS, Korea)

Overview:

The workshop is designed for summarizing and sharing recent achievements of PCS members during 2020 and 2021 and discussing about the overall direction for our center to develop in this year and the next year. Workshop also promotes interaction between internal members of our center as well as discussion with other groups of research fellows from APCTP in order to develop new ideas for promising future research directions. The primary goal of the workshop is to foster interaction and collaboration between researchers from different backgrounds through talks and informal discussions. During the workshop we will hold many talks as well as in-depth discussion sessions. Numerous occasions for scientific interactions are expected to motivate new collaborations, and ultimately to make new research results of excellence.
