Colloquium Schedule

Colloquiua will be offered with some combination of in-person and remote colloquia. 

Our normal colloquium time is Friday at 3:00 in the Biology Annex (BX102) with refreshments at 2:45pm in the Astronomy Conference Room (AY 119). We will normally try to broadcast these via Zoom at Note that student proposals/defenses may start at an earlier time or alternate time to allow for a subsequent committee meting.

Contact Jon Holtzman (holtz at with questions or comments about the colloquium and to set up a date for a colloquium.
