The workshop will be centered around the recent revival of the conformal bootstrap idea in three and four dimensions, and the related areas of strongly coupled QFT dynamics. We will also bring in speakers in condensed matter, statistical mechanics and lattice studies, to emphasize connections with physical systems. The format will include a light program of talks in the first week and even lighter one in the second, to leave plenty of time for discussions. Organizers: João Penedones (Porto), David Poland (Yale), Leonardo Rastelli (Stony Brook), Slava Rychkov (CERN), Pedro Vieira (Perimeter)
