Fourth international meeting of the

Global Invertebrate Genomics Alliance


16-18 November 2021, online

Welcome to the Fourth international meeting of GIGA!

NemerteanFollowing three successful in-person meetings in 2013 (Fort Lauderdale, Florida), 2015 (München, Germany) and 2018 (Willemstad, Curaçao), the Fourth international meeting of the Global Invertebrate Genomics Alliance will be held online due to the current pandemic. Presentations regarding all aspects of non-vertebrate genomics are welcome.

Presentations will be broadcast online over Zoom. They will be recorded and made available to registered participants for two months after the conference.

The meeting will be spread over three days (Tuesday 16 November to Thursday 18 November), for three hours per day: 7:00am-10:00am PST, 10:00am-1:00pm ET, 3:00pm-6:00pm GMT, 4:00pm-7:00pm CET, 10:00pm-1:00am ICT, 12:00am-3:00am KST&JST.




Each day will comprise two sessions with a 20-min coffee break inbetween.

Here is the detailed schedule:
