Department Lunch Talks

Weekly talk series with three 12+4 minute talks, typically featuring two local scientists and the scheduled astronomy colloquium speaker.  Subjects include not only personal scientific research, but also arXiv/journal-club style reports, education and public outreach efforts, science policy, and professional development issues.

Day and Time: Thursdays at “12:30” (12:40–1:30)
Location: 131 Campbell Hall (rooms A & B)
Organizers: Luke Kelley

To volunteer for a talk, please e-mail Luke (LZKelley  Berkeley graduate students and postdocs are given priority for talks, but visiting scientists and collaborators are also welcome to present.  Visitors should have their local hosts contact Luke to facilitate scheduling their talk.

Speakers are recommended to bring their own laptop, cable adapter (although we have some), and pointer.  Presentations may also use the whiteboard.  Please contact Luke ahead of time for any special accommodations.
