When my work is presented by colleague at conference I don't attend, do I include on my CV? My colleague has been presenting our work overseas. I'm primary investigator and first author on the work/papers. Should I or can I be including these presentations on my CV?

My context is that I'm a doctoral student in healthcare discipline and using the CV for grant applications.

Thank you!
Credit for a presentation doesn't go only to the person who gives a talk or presents a poster. Everyone involved in the work should be acknowledged.

The standard practice I've used is credit everybody involved in the research on the poster. So if I give a poster presentation, I include any students, postdocs, or colleagues who collaborated on the research. I also indicate who the presenter was if it wasn't me.
