I am surprised that it's for only 1 researcher though. The data on startup founders seems to encourage 2 or more people to share the burden and have someone to more explicitly bounce ideas off of. It would seem to be the case that fundamental research like this would also benefit from the cofounder type setup.
The researcher we choose will be fully a part of YCR / YC. He or she will be able to bounce ideas off us at any point, and we will help out however is requested.
