Welcome to the Collagen Café!

To share the pleasure of collagen research with our colleagues. To build the international collagen research community. To hear fresh voices. Expect 2-3 Cafés per year. Please email adr@dal.ca to recommend future talks, or to volunteer for one.

EDI principles: While this Collagen Café is about developing our community and exploring research ideas, it is also about supporting, training, and offering ethical leadership for trainees and early-career researchers. We want to be visible leaders in our efforts for Equity, Diversity, and Inclusion (EDI) in this Café and more generally.  We encourage trainees to actively participate in the Café; we promote underrepresented groups within STEM, including women and visible minorities at all career levels; and we recognize the continuing debts we owe to the peoples historically displaced by our institutions and our homes.

Zoom etiquette

•    Use chat to ask questions during talks. “Raise your hand” (see participants in Zoom) to ask questions after talks (remember to unmute when you are called). Please mute otherwise. Please keep your video on if possible to give all speakers an engaged audience.

•    Rename yourself in the style of “Jo Smith (University)” (see participants & more in Zoom). You can share other information (pronouns etc.) if you would like to, of course.

•    Each talk has a duration and a discussion period.   We encourage all speakers to use headsets and to test audio before their talk. All speakers will share their own slides over Zoom.

•    In the event of technical issues that cannot be immediately resolved, we will go to the next speaker. If needed, dropped speakers can email slides to the organizers and phone into the meeting. We will try again after the next speaker has finished.
