Which institution's logo to add to research poster when research was done at institution different to main affiliation as student? I am a student at the North Carolina School of Science and Mathematics, but did research over the summer at Duke with a mentor from Duke, as part of a program run by NCSSM. I am currently creating a poster to present my work, and I do not know which institution's logo it would be appropriate to include. When I am adding a logo to my poster, what am I acknowledging that the owner of the logo has provided? It seems to me that both institutions have provided me with support, so I do not know which one I should acknowledge. I suppose that I could add both, but I would rather save that space for content. What is the protocol for situations such as this one where two institutions have provided support to a project?
If both institutions have supported your project, you should acknowledge both in your poster.

To save space, you have a variety of options:


Make the logos smaller by scaling them.
If available, use a small, square version of the logo rather than a larger rectangular version.
Put the logos in a part of the poster that is underutilized. (For example, left-align the title and authors, and put the logos over to the right side next to the author list.)
