Be clear, don't be verbose, be polite, and be grateful, thanking them for their time and contributions. Be sure to mention that the award was what triggered your curiosity.
Also, make sure to ask them to put you in touch with the right person, if they aren't the right person. You're probably looking for someone with 'materials' near their name. There may also be a coordinator for the project. If so, first try them.
Seriously, go ahead and ask. Chances are, you're even welcome to ask follow up questions. I'm retired but I always enjoyed it when people legitimately wanted to know more about what I was doing. It was only a problem if I was busy, but I still made time. It just sometimes took a while.
