Spring 2023

In-person only, 12:40 - 1:30 PM (Pacific) every Thursday, location = 131 Campbell Hall

To volunteer for a 12 minute talk + 4 minutes for questions, send email to Paul Kalas (kalas@berkeley.edu).  

This forum is mainly for local scientists of any level to present their work to a broad spectrum of the department, and usually includes one short talk by the astronomy colloquium speaker of the day. 

Subjects can include personal scientific research, reporting on other work appearing in journals, education and public outreach efforts, science policy, and professional development issues.

Scientists from other institutions need to have a local scientist hosting their visit to Berkeley before they can request a talk slot.

Note that the projector will fill the screen and make slides easier to read if a 16:9 format is used.
