UPDATE: New Dates and format for the Barrett Lectures

The 50th Barrett Lectures were originally scheduled to take place May 11 – 13, 2020. Unfortunately, on March 11, 2020 The World Health Organization  declared COVID-19 a global pandemic. For this reason, and after consultation with the NSF and IMA offices, we had to postpone the Barrett Lectures.

We are glad to announce that we have found a new date for this meeting. It will take place

May 17 – 19, 2021

online via Zoom.

Attending the Lectures is free, but we require all participants to register. Click here to register.
