Where can I contact Archaeologists that reside in England, Wales, Ireland, Scotland?

Hi, I am an Undergrad Student at Albion College in pursuit of a career in Archaeology. I am really interested in talking to people in the above location fields. Any information on schools of these locations would be great! Also advice is very welcomed and wanted. I am specificaly interested in the Celtic culture, Irish Folklore, medieval weaponry, and the Pagan religion. Pretty much everything in the above places.
