This workshop was originally scheduled for May 2020, but was postponed due to COVID-19. There is now an in-person Plan A and a remote Plan B. If it is safe and feasible to hold an in-person workshop, the workshop will occur Wednesday May 5th – Friday May 7th, 2021. If not, the workshop will move online, with talks prerecorded and discussions and hands-on training occuring over three consecutive Fridays: April 30, May 7, and May 14th, 2021.
