Hello! I received a B.S. in mathematics at UCLA with minors in philosophy and coding, and then an M.A. in math here at Brandeis. I am interested in Topology but have not yet decided what to focus on. I enjoy playing guitar, exploring, having philosophical debates, and living with intentionality. Here is something to ponder: is the sentence "The king of France is bald" true, false, or some third thing? Ask me about it!
