For bookings etc please email details to firstname.lastname@example.org. If I can’t make it I’m happy to suggest others.
I’m always happy to hear about interesting work, but I don’t normally respond to unsolicited requests for help with coursework, including answering surveys or doing interviews, unless the results are going to be shared widely.
I’m happy to do peer reviews, but for academic papers/articles, I only do that for diamond/platinum open access publications (i.e. free for both authors and readers).
