Hi. I am looking into summer programs for the upcoming summer. I am interested in programs with focus in math and/or computer science. Last summer I did a physics REU at Columbia, and this summer I was hoping to maybe do a program somewhere in Europe. Maybe Cambridge, ETH, or Oxford or some such. Since REU is funded by NSF it only exists in US schools and since I knew of no such European program I resorted to googling but that didn't turn up much. So, does anyone know of good academic summer programs in math and/or computer science hosted by European schools? Thanks for the help.
