I've spent most of my career doing geometry—as a researcher, a teacher, and most recently a software developer. My research focuses on geometric topology and its connections to mathematical physics. My contributions to Wikipedia include removing an unnecessary "i.e." from the article on gelding, finding a printed reference to a 17th-century Ottoman coffee ban, changing a hyphen to an en dash in the article on the Rome Statute,^[1] and starting an article on Yefim Dinitz. I'm not great at selfies, so I won't post one here. In its place, please enjoy this picture of a squid.

If you see a potential problem in a reference I've made to a non-English source, I'll be grateful if you leave a note here to help me improve my comprehension.

Besides the language skills shown in the Babel box, I have a tenuous sense of conjugation, declension, and basic function words in Russian and—even more tenuously—Hebrew. To use sources in those languages, I scan for relevant passages using text search and machine translation, get a rough read of each relevant passage by going word by word with a bilingual dictionary, and then use Wiktionary to look up conjugations and declensions that I find especially important or can't guess from context.
