My name is Kaj Hansen. As an undergraduate, I studied mathematics at the University of Georgia. I am a mostly passive Wikipedia user, making readability edits and fixing typographical and grammatical mistakes as I find them organically. I also frequently add Wikilinks to articles when appropriate because thoroughly Wikilinked articles significantly improve the user experience for those like me who "Wiki spiral" (opening many articles in new tabs as one reads).
Nevertheless, I have authored significant additions to a handful of articles, notably "List of psychoactive plants, fungi, and animals" and "Substituted phenethylamine".
