It was a meaningful opportunity for family, loved ones, students, colleagues, and friends to join together in remembrance. His obituary can be found here.

The following note came from Douglas S. Clark, the UC Berkeley Dean for the College of Chemistry

Phillip Geissler (1974-2022)

Our community has been jolted by the news that Professor Phillip Geissler, 48, has died.  Phill was hiking in Utah at the time of his death.

Phill was the Aldo De Benedictis Distinguished Professor of Chemistry and a renowned physical chemist, but many of us will think first of his easy smile and his deeply engaging personality.

Phill was a truly remarkable person–a brilliant researcher and scholar, a phenomenal teacher and mentor, and a dear friend to so many. His students found him to be both accessible and caring. He received numerous awards during his career, but he was proudest of his UC Berkeley Distinguished Teaching Award that he received in 2011.

I send my sincere sympathies to his family, colleagues, and friends.

We will provide more information as it becomes available.
