 (I receive an unhealthy number of emails per day which makes me feel very overwhelmed. Please consider not sending your email unless it is really necessary. I apologize if I miss your email - I give response priority to my students (undergrad and grad), Princeton staff&faculty, and my collaborators.)
Questions about the ORF 363 waitlist? Please read this before emailing me.
