Your university commercialization office will disagree. Check with them. From what I understand, it is illegal to release your code in CC0 or MIT unless you have taken permission from the commercialization office (Some universities allow GPL without explicit permission). Have you checked your contract ? Your work is not yours if it has any value. The value belongs to the university (mostly) - which also means you have no incentive to work on valuable stuff.
