I am a PhD student, and also trans (MtF, she/her). I've recently done some work with a research group based at the same institute as me, and this has led to me being CC'd in a few emails to various people, some of whom I don't know, and most of whom I don't know very well.
There is a senior academic who I have known for several years, since long before I came out as trans. They are definitely the most well-known and senior person involved in any of these email chains (not only because of academic rank, but because they are highly respected by just about everyone in the field). They are a very lovely person who I respect greatly.
Unfortunately, they have (I assume) accidentally misgendered me while referring to the work I contributed in an email that was directly addressed to a few people I have never met (although I do know of them). CC'd are a number of people who do know me.
My question is essentially: what is the best way (if any) to address and correct the misstep?
Since my pronouns are in my email signature, I had initially tried to find anything I could send in the (now growing) email chain in order to make it clear to everyone what my actual pronouns are. However, I don't think there is anything I can contribute meaningfully, and I'm only CC'd in the emails to keep me up to date with the status of the larger project.
I also don't think it's an egregious mistake done in bad faith. Like I said, I have immense respect for this senior academic, and I have not at all perceived any change in their attitude towards me since I came out. So I believe it truly is an honest mistake that happens from time to time, so if I don't have any way to casually correct it I think I'll just leave it.
I'll also point out that if this had happened during a meeting or conversation, I would have immediately corrected it. The problem here is that it's in an email chain I don't really have any other reason to intervene into, so it feels unnecessary to send an email and add to the length of the chain with no more than a correction to something I don't think was done intentionally.
