1st International Diplonemid Conference - IDIPCON

1st International Diplonemid Conference iDIPCON

2 - 3 April 2025

Virtual event

General Information

This is the first international conference to gather researchers working on diplonemids - one of the most abundant and diverse marine micro-eukaryotic groups known today.

The conference is held virtually, allowing a geographically-broad audience to participate and promoting inclusivity, accessibility, and sustainability.

Presentations cover four different research fields, each forming one session:

Mitochondrial Proteome & Macromolecular Complexes
Ecology & Evolution
Phylogeny, HGT & Symbiosis
Metabolic Pathways, Physiology, Morphology

Speakers

Fourteen renowned speakers have been invited. Additional ~15 will be selected based on their submitted abstracts.
