Dinophyte Seminars


 International seminar series on dinophytes

Because of the current pandemic, we have been unable to meet each other. This is a shame because such meetings are crucial to keep our community connected.
To overcome this, in line with the DINO/ICHA-conferences, we invite you to participate in: 

Our biweekly 20 minute seminars + 10 minute questions via ZOOM, starting in May 2021 (We'll try to choose timeslots that are convenient with your time zone) please note that the scheduled time is Central European Summer Time (GMT+2).

This can be about anything related to dinophytes / dinocysts (for example about taxonomy, phylogeny, evolution, life-history, toxins, pigments, transcriptomics, (paleo)ecology, stratigraphy, functional traits, ...).

If you would like to attend these seminars or present such a seminar, please contact, and we'll provide you the necessary information.
We specifically ask postdocs, PhD students, MSc students to propose seminars.

This is a good way to showcase your research to a group of specialists.
