If your student would like more background, then there is only one way to get that: Study a lot. There is a reason that it often takes years to get a research degree (Ph.D.).
So, if you by "bringing someone up to speed" mean that you want the student to learn the background, then I believe this would be very hard unless your student is very bright and highly motivated.
But if you by "up to speed" mean that you want the student to be able to help in carrying out the research, then one way to do that would be to do a lot of concrete computations. I mean, you forget about the background and the larger perspective and learn about a concept from doing concrete examples. Much research involves specific computations that one doesn't need much background to actually do. While doing examples you can slowly build up the background.
the challenge for you is that you have to break up the research into parts where some of these parts can be attacked by someone who doesn't have much background. This, of course, isn't easy in some areas, but maybe you could do this - in particular because your area is somewhat new.
