I have been working on a health related project since 2010. Tons of documentation, prototypes, testers, etc. I recently went back to school part-time to switch fields, and thought adding research would help. I managed to convince a professor, who had access to some helpful data, to let me continue my personal project with the new data, in exchange for having a reference later in the future field. All of the work, and ideas have been mine, although he has been helpful in reminding me to move forward and has had a few connections at the school to bounce ideas off of.
This brings me to the present. In a month I will be presenting the fruits of this research. And although the results are not spectacular (yet), he proposed off-handedly that "we" should work on monetizing it afterwards.
I'll repeat, he knows full well that I was already working in that direction before I even met him (I already have working phone applications, and have bought domains). And have at no time suggested that I would bring him aboard afterwards. I don't want to alienate him, as I would like to have a good reference for later, but I also don't want to just let this sit and him come after me years later if I do make money off of the research.
Any thoughts or suggestions would be greatly welcome.
