The final program is here! Submit your abstract through June 24!

Friday, October 28-Monday, October 31, 2022

See below for the featured programming

What is the theme of the meeting?

From Organism to Omics in an Uncertain World.”  Traditionally, comparative physiologists have aimed to understand basic animal function while also gaining insights into ultimate causation and the evolutionary or adaptive significance of a physiological process or trait. But our work has become center-stage as it provides extremely valuable insight into vulnerable species’ responses to climate change and other anthropogenic factors. Simultaneously, the dawn of the genomics era and major advances in computing power and imaging technologies have accelerated the integration of molecular, cellular, morphological, biomechanical, biophysical, ecological and evolutionary data into our work. This meeting will highlight how these integrative approaches are being used to understand both long-standing and applied problems in comparative physiology.

Will this be an in-person meeting?

Yes! We are planning for this to be a conventional, face-to-face meeting with all of the usual elements.

When will the meeting be held?

October 28-31, 2022.

Where will it be held?

The meeting will be held at the Westin Downtown in San Diego, CA on Broadway.

Who is on the organizing committee?

You can now submit an abstract to present a talk or a poster here.

We will draw on the submitted abstracts to build abstract-driven oral sessions. There will also be two daily poster sessions.
