Resurrecting old research done at another university. Do I need permission from previous supervisor to publish, and how should I credit? About 5 years ago, I did a Masters of Research (MRes) part of which was a supervised research project. Because of time constraints (Masters degrees are only one year in the UK) I was unable to gather enough data to generate any publishable material (though I did produce a thesis which I believe is in the university library probably gathering dust).

Fast forward to today, and after a lengthy break from academia I'm now doing a PhD at a completely different university at the other end of the country, but in the same field. I would like to (workload permitting) try and finish what I started and publish a paper from it using the expertise and equipment I have available. My concern is because this is a continuation of research started a long time ago at another university, whether this would present any issues or barriers to publication or even conducting the research itself.  

Regarding my previous supervisor, I am intending to inform him of my intentions at least as a courtesy, and I honestly can't imagine he'd have any objection, but if he did, would I have trouble publishing any work from it? Would the university itself have any grievances? Some of the work he did on the project concerned a novel sensor design which was mostly unrelated to the main scope of the project, I will not be including this work in my publication, would this be a problem?

I'm also wondering how to credit him. Since I'll be writing a new paper from scratch, I'm not sure if I should include him as a co-author. I would at least like to include him in the acknowledgements if it's appropriate.

My current supervisor is happy for me to do this as a side project, so there are no issues there.

P.S. Before anyone asks, yes I have done due diligence and checked that my research is still novel (so I've not been "scooped" by someone else).
There should be no problem whatsoever, but it would be correct to both inform your previous supervisor and make him/her a co-author. Importantly, they should read and be allowed to suggest edits to your manuscript which may both enhance it scientifically and its chances of success at review. It's a win-win approach in my experience since you both benefit. In no way does this dilute the level of your 'ownership' of the paper or your intellectual input, and indeed, if your supervisor is well known in their field, you may also benefit from the association.
