Back when it was a Sonic OC, the field of study was based on where it lived as it was an island full of ancient ruins that no-one knew how or why it came to be. So it specialised in excavation, preservation and also the language of those Ancient Builders. What's amusing of course is I had them as aliens and then Sonic Frontiers happened, I won't spoil but Ha Ha :)

Post Sonic I've obviously lost the rest of the angle I was going for but it would still be in excavation, preservation and interpretation. I'd also add in that Simon generally made the conscious choice to pair that with university work because they dislike what a lot of older museums represent. They're not opposed to museums and would encourage local museums, but, y'know what the old ones are like.
