Oxford had… I... I was back in a place with... with graduate students, as opposed to Princeton which had only post-doctoral fellows and... and so on. And so life in Oxford from then onwards, was...was, there was substantial involvement with the... with the research students that I had, of… you know, many of whom with... with great success. I had a lot of good students at various… although, ups and downs. I mean there were fallow... fallow periods and fruitful periods, but so the involvement with the research students there played a bigger role in… And I think later on, you know, when I look back on it, I realise that, you know, that was… that would never have happened had I been in Princeton. I would never have had research students… well not quite.

Well, that's not quite true. I mean, George Lusztig was a kind of research student of mine in Princeton. You know, he... he came over, you know, as a young Romanian without a degree and, so he came to Princeton. He was… not really, maybe my assistant formally at some stage, and he... he was doing a degree, technically at Princeton University, under Bill Browder, because the institute didn't give degrees. So you know… but effectively he was working with me and he did his thesis with me at the institute, but the university nominally gave him his PhD.

But that was rather exceptional. So except for that, there weren't really PhD students, and my being in Oxford over a long period of time I acquired, you know, a substantial number of... of students and probably did, through... through that, influencing students and... and what they did, you know, had more success than I would have done if I'd stayed on in the institute for another, you know, 10 or 15 years. So I think that it worked out well, and... and I… although I hadn't probably thought it all through that way when I came... came back.
