phd - How to deal with supervisor who required me to share all my work with him?

I am graduating with my Ph.D. very soon. In addition to my thesis and published journal papers, my supervisor required me to copy all my work—code, figure files, data, etc.—to him before my leaving. However, all the works during my PhD have been done by myself from scratch, including the ideas and research gap searching, although he was the co-author of the papers. And my scholarship has been provided by the university. So I feel this requirement is not reasonable.

In fact, my supervisor didn't like my research topic and we had very little communication during my Ph.D. study. He gave me very little help on my work and was also never interested in my work and research field. In this case, could you suggest me on the following two specific questions:

1. 
   

   Should I share all my works with him? If yes, why and if no, how to negotiate with him?

   
   


2. 
   

   If I can only share partial works with him. What is a good strategy?

   
   

Answer

It is highly likely that you have a clause on "inventions" and/or "invention disclosure" which you may have signed during your admission process. If you still have it, refer to it to see what it says. In most cases, the ownership of the IP and any related materials belong to the University and so your supervisor is supposed to have a copy of your work for archival purposes.

If you do not have it, the admissions office of your department/university may have a copy of the official policy which you can refer.
