This is the way to thank your speakers! A super cool T-shirt! Among the immunology puns on the back:
"We go with the flow.
We get our FACS straight.
We don't let lineage markers define us.
We have diplomatic immunity.
We're adaptive, tolerant, and diverse.
Our enthusiasm is infectious.
We are positively selected."
It was a lot of fun to lecture for their Computational Systems Immunology Series. Dinner with grad students was also fantastic. Lots of fun discussion, and I had a memorable visit with Lee Herzenberg's lab, who have created some interesting new cytometry software.
