Nice! I actually attended there as an undergraduate many years ago. Prof Bui still remembered my name, even after my military -> industry -> academic -> industry journey. As in most institutions I've been in, if they're already familiar with your work then there's little process for getting an adjunct position because of the demand (as explained in the article). Just don't expect interesting courses right off the bat.
I do have to warn you, if you're not already aware... all those articles about lack of student engagement due to pandemic are horrifyingly correct. I started adjuncting as the pandemic hit and it seemed like each semester was worse than the previous one. I just finished up my last course and it was such a slog. People barely show up, are completely silent when they do. A root canal was more fun.
That said, it's a great feeling when you really make a connection and I hope to return to teaching sometime in the future.
I will put my psu address in my profile, if you want to connect.
