Pronouns: he/him/his

I am a PhD student in math working with Dr. Carolyn Abbott in geometric group theory. Before that, I studied math at UCLA with minors in philosophy and coding. I enjoy playing guitar, exploring, having philosophical debates, and living with intentionality. Most americans pronounce my name [ˈɹɑχ-mi-ˌɛɫ] which is fine with me. Here is something to ponder: is the sentence "The king of France is bald" true, false, or some third thing? Ask me about it!
