The deadline for the Google Policy Fellowship is Monday, January 25. Check out our internship description here. The deadline for the Charles G. Koch Summer Fellow Program, run by the Institute for Humane Studies, is Sunday January 31.
Both programs run 10 weeks and offer stipends. The Koch Program (which I participated in) is specifically geared towards those interested in free market ideas, and includes an excellent retreat, ongoing series of lectures, and group research project. As a "Koch-head" myself (class of 2000), I can attest to the quality of the program and the value of the alumni network. The Google program is in its third year but will, I'm sure, develop a valuable alumni network of its own.
Of course, we could always use extra help, so if you're interested in an internship during the school year or over the summer, don't hesitate to let us know by emailing us at mail <at> pff <dot> org. We may not necessarily be able to pay you but, hey, no one ever went into the think tank world to get rich!
