Our lab is having its holiday party tonight at a somewhat fancy hotel restaurant. How do I address a PI of our lab? I’ve never met her this semester – she spends time at another research institute and communicates with us via group emails.
Given that a party will be a casual meeting, how should I address her? By her first name, say, “hi Karen”, or is it better to address her more formally, such as “hi, Dr. Samsonite”? Our lab consists of about twenty members.
