Professor Elm runs his laboratory out of New Bark Town, where he lives with his wife and son in a modest house nearby. His kid idolizes him and wants to follow in his footsteps as a Pokémon Professor someday. He's got an aide working in the lab to help keep things running.
The guy's pretty scatterbrained when he gets deep into his research—his wife will tell you he forgets to eat regularly once he's caught up in his work. He's huge on Professor Oak and considers him a major influence; turns out Elm was actually one of Oak's standout students back in university.
These days, Elm focuses on researching Pokémon Abilities and has a broader interest in how life originated. It's the kind of deep, theoretical work that probably explains why he zones out so easily.
