Join us on Wednesday afternoons for the CDAC Webinar Series, featuring speakers from the high pressure research community who discuss their work in an informal, online seminar format. The CDAC Webinar Series started in 2020, and we have hosted over 100 sessions since the inception of the program. Recent sessions have been recorded and are available on the CDAC YouTube Channel.  To be added to the mailing list for seminar announcements, please contact the CDAC Coordinator.
