UC San Diego's Center for Circadian Biology will host its 14th Annual Circadian Biology Symposium to be held at the Sanford Consortium - Roth Auditorium, UC San Diego.


We have invited a select, stellar group of chronobiologists from around the country and beyond, and a few local colleagues, to speak at this symposium. Each year, the symposium attracts leaders in the field, with active participation from our 58 PIs within the CCB. We welcome and encourage registrants from your research personnel, other institutions, and industry.

The aims of the conference are to:

  1. Provide participants with a comprehensive view of modern circadian biology.
  2. Exchange a broad spectrum of ideas and techniques in circadian biology.
  3. Promote interactions among the faculty and lab personnel of UC San Diego, Circadian Biology Center, the invited speakers, and other participants.
  4. Further acquaint the speakers, their groups, and other registrants with the depth and breadth of circadian biology research conducted at UC San Diego.

Network Awards

CCB will award a limited number of scholarships to to enable undergraduates, gap-year students working towards a graduate program, Masters and PhD students, and scientists within the first 48 months of postdoctoral training to attend this symposium.

Network Awards will fund trainees whose activities and experiences contribute to expanding the diversity of scientists involved in biological rhythms research.

Recipients of the award will receive a full registration scholarship. Recipients from outside of the San Diego area will also be reimbursed for travel and housing expenses to fully support attending the conference.

Applications include this form, a short CV uploaded with this form, and a statement from your mentor triggered by completion of this form. Application materials must be submitted by December 15, 2023, and mentor letters by December 20, 2023. 

Applicants will be notified of decisions by January 10, 2024. We recommend that applicants wait until the funding decision to register for the symposium.
