I am a bachelor student and have been working for a professor since the last two years on a paper for which I was paid. All the work is mine but data belongs to him. We recently had a fallout and I no longer work for him. But the paper is completed and only submission part is left and at this stage he has stopped communicating with me. I have tried writing to him more than three times and there has been no answer. Only I have worked on the paper and it's a method paper.
Can I publish without him? Can I put his name and send out for publication even if he does not agree ( or respond to mails)?
Or can I take method paper to a different lab working in the same area and then publish using their data?
What can I do now?
Edit: I don't think I am an over confident bachelor student trying to aim for nature or a Nobel. I verified with multiple people and all of them has stated something along this line "that though the work won't make it to any top tier journal still has more than enough new contributions for a paper".
The problem is that me and my supervisor ended up having a fallout over some slight remark he made about me, which I felt offensive and was not diplomatic in calling that out in a skype call with other lab members. Since then he has terminated by contract and won't reply to my mails.
My professor works in Economics (data) and the paper is around Bayesian approaches on this data (Stats, AI).Other than the data, there has not been any intellectual contribution from my professors side.
