I have an appointment to discuss a food chemistry theory I've developed with a professor at a nearby University to see if it can be advanced in any way. My concern is how to approach the issue of a Non-Disclosure Agreement with the professor. I know that there is a code of ethics which is generally followed in academia, but this concept carries a potential upside which could be substantially lucrative, and I'd like to protect myself as much as possible. Any suggestions on how to proceed would be greatly appreciated!
