I'm a new professor in an engineering/science field. I am a theorist, but not because I don't like to tinker around with things in the "real world"! I guess I need some nicknames here: if I'm the "Tinkering Theorist", my husband should be "Tinkering Experimentalist" (TE). Our kid is a bit too young to be a "tinkerer", but he definitely likes to poke at things, so he is the "little poker" (LP). I have an "even littler poker" (ELP) too! Also, now I do simulations in addition to theory.
