The Protein Dynamics Workshop, which is held every other year, is a forum for presenting and discussing results from the application of state-of-the-art experimental (including, but not limited to, optical spectroscopy, NMR spectroscopy, X-ray crystallography, and scattering methods) and theoretical approaches to studying protein dynamics. The Workshop is a small focused meeting with approximately 30 attendees, all of whom give oral presentations on their work. The small number of participants encourages relatively lengthy presentations and extensive discussions. Despite its small size, the meeting is very international in scope, with attendees from North America, Europe, and Asia.
