"One of the values of a group like ISRS is that it's like minded individuals coming together, collaborating, sharing ideas. And a meeting like this every couple of years is very reinvigorating because you remember that other people are interested in the same things that you are. And we're all talking about the same types of topics. And it's really lovely to be able to do that in person instead of virtually. You don't get the same impact that you do when you're together as a group."
