Scientific Computing Seminars

Mission:

The Scientific Computing Seminars are intended to present and promote discussion of computational and computer science activities by members of CRD, collaborators both inside and outside LBNL, and others in relevant research communities.

Format:

Most of the seminars are presented on Fridays from 1:00pm-2:00pm in 50A-5132 Conference Room.  However, the date, time, and location of each are subject to change.  The seminar calendar should be consulted for any last minute change.  Informal brown-bag lunch gathering from 12:30pm-1:00pm is encouraged at the location of the seminar.
