How to include volunteering work in CV (as a PhD)? I defended my PhD in Dec 2017 and then stepped away from academia for a while and decided to pursue other stuff. I realized I wanted to change fields and started reading books and papers about it and even contacted a local prof to write a review paper about that topic, which he accepted. Now I finished writing that paper and I'm just waiting on the prof to finish his part and we're gonna submit it in a month or so. What I'm wondering is - how do I present this in my CV? I was writing the paper since Nov/Dec 2019, so I spent a bit over 3 months on it (it's huge), and I'm wondering if I should put that under "work experience" on the first page, or under "activities", which are on the second page.

My initial idea was something like:

+------------+---------------------------------------------------+
| 2019-2020  | Volunteer work, Institute X, Department Y, Lab  Z |
+------------+---------------------------------------------------+
|            | Project: "Name of the review paper"               |
|            | Supervisor: Dr. Proffy McProffson                 |
+------------+---------------------------------------------------+


I'm just trying to make it look like I did something of substance and I'd like to present that volunteer work in the best possible light, so that I have better chances of landing a position. Which is pretty hard, since I've been away from academia for so long.

Any input is welcome. Thanks.
Don't claim supervision nor volunteering without an agreement. (I'd consider that lying on your CV.) Your work was conducted as a hobby or as professional development or ..., which don't easily fit on a CV and their presentation will depend on the position you're applying for. E.g., for an academic appointment, you could include this information in a covering letter or in your CV's opening blurb.
