Because of COVID, we had to cancel our in-person meeting at Cal Poly San Luis Obispo last March 2020.  We had planned to come back in person to the same location in 2021. However, because of COVID concerns, and the risk of not having a vaccine and adequate air travel next year, we decided to do the meeting virtually on zoom in 2021.  It will be 2 days from 8 am to 1 pm, March 23-24, 2021.  We will have a keynote speaker each day, student talks for the scholarship competition, and regular 10-15 minute talks as usual.
