Professor Elm works at his laboratory in New Bark Town. He lives in a small house near his laboratory with his wife and son, who wants to grow up to be a Pokémon Professor like his dad. He also has an aide who assists him in his laboratory.
Elm is known for being a little scatterbrained and disorganized when he gets wrapped up with his research—to the point that, according to his wife, he sometimes forgets to eat. He holds Professor Oak in high regards.
Professor Elm was one of Professor Oak's top students at a university. He currently specializes in the research of Abilities and has interests in the origins of life.
