Our IPAC community is in shock at the sudden loss of our colleague and friend, Carl Grillmair. His curiosity and dedication shaped IPAC in countless ways. We've dedicated our science talk series, The Next Seven Minutes, to his memory.🔭 www.ipac.caltech.edu/news/ipac-mourns-passing-of-carl-grillmair

This is an image of Caltech astrophysicist Carl Grillmair.

Visual description: The image focuses on Carl's head and shoulders; he is wearing a white shirt with gray stripes with short sleeves, and he is looking directly at the camera and smiling. Carl has a busy brownish-red bear and hair and with gray eyes.
