 Scientific and Educational Sessions – February 29 and March 1, 2020


NEW THIS SPRING:  Poster Blitz!

In response to your feedback to have time with the authors at their posters, we are introducing a Poster Blitz. The Blitz session is a rapid series of brief presentations where you have the opportunity to advertise your poster(s). You will be given 70 SECONDS to “sell” your scientific content and convince other participants to visit your poster.  This session will be paired with a cocktail reception and provide dedicated time for presenters to be at their posters.
