How can I set up a fund to support academic research at a particular lab using my own money?
Talk to your attorney or certified public/chartered accountant and the development or giving department at the university in question. Both deal with these kinds of issues constantly. You need tax advice in your location and giving advice in theirs. These are common questions for universities which like to receive charitable donations and want their donators to be best advantaged in their contributions. They may be able to recommend attorneys and accountants with experience in donation laws in your and their jurisdictions.
