SDB-PASEDB Satellite Symposium 2022

Satellite Symposium - Joint SDB and PASEDB Meeting 2022

Genomic Basis of Developmental Evolution in Chordates

Organizers: Ingo Braasch, Andrew Thompson, Olivia Fitch (Michigan State University)

This satellite symposium will occur prior to the opening of the

Joint SDB-PASEDB Meeting 2022 Conference

co-organized by the Society of Developmental Biology (SDB) and the
Pan-American Society for Evolutionary Developmental Biology (PASEDB).

Our symposium will bring together researchers from all career stages that are studying the evolution of developmental mechanisms in the genomics era. The recent explosion of genomic, transcriptomic, and epigenomic data from all lineages within the chordate phylum allows for developmental interrogations of the genomes-to-phenomes map and spurs conceptual advances for the understanding of chordate biodiversity.

New technologies like CRISPR gene editing and an avalanche of multi-omics data is generating an overwhelming number of new discoveries that are revolutionizing developmental biology and the understanding of ontogenetic evolution. Bringing together early career and established researchers at a time when the field is moving at such a fast pace is critical to continue this momentum and bolster the next generation of evolutionary developmental biologists.

The symposium focuses on chordate animals, a lineage that includes a diverse array of organisms from cephalo- and urochordates to fishes to humans. Consequently, this is an important lineage to study biodiversity as well as to understand our own evolutionary past and its connections to human developmental diseases.

Date and Location: The symposium will be held in person on July 17, 2022, 9:30 AM - 4:00 PM at the
Sheraton Vancouver Wall Centre in Vancouver, BC, Canada.

Registration: Select the symposium at no additional cost when registering for the main conference (link).
Early, discounted registration deadline is May 9, 2022. Regular registration after May 9 until June 13, 2022.
Registration is now closed and there is no on-site registration.

Abstract submission: In addition to our invited speakers (tentative schedule below), we will select 6 abstracts from contributed abstract. Submit your abstract by April 11, 2022 through the main conference website (link). Abstract submission is open to all career stages, but preference will be given to early career scientists (postdocs, graduate students). Abstract submission is now closed.

Health and Safety: The satellite symposium and the main conference will be held in person. Please see the conference website for details regarding COVID-19 regulations (link). You will need to provide verification of your vaccination status (link).
