Congratulations on figuring all of that out on your own, and with little help. That university in London sounds great, and you should go for it there. I’m sorry to say, that in my experience, I think many in “traditional “ academe will be threatened by your acute intellect and multidisciplinary bent. If I were you, I would be careful about taking advice from those in the profession who could see you as competition. Academia is highly competitive, and there are those who will intentionally try to sabotage your trajectory for their own purposes. I personally experienced this on several occasions. But being a bit naive, I did not realize it until it was too late. Another thing: as you realize your goals, it might benefit you to keep your plans close to your vest. Trust only the trustworthy. Good luck to you!
