If I shared the same last name as my spouse I might clarify by saying "in work with Dana Zygomorphism" instead of just "Zygomorphism", because that might be awkward for the audience and I might lose some of them for a few minutes while they mull it over.

Also, in a job interview of doom I kept referring to "my partner" with whom I had started a company and built a website, and the senior interviewer had the gall to ask me "and by partner, I'm just curious, you mean...?".
