Professor Willow is the go-to Pokémon Professor in Pokémon GO. He's basically the game's guide and mentor rolled into one, helping players get started and learn about Pokémon as they explore the world.
Like Professor Birch, Willow focuses on how Pokémon live in different habitats and where they're distributed across regions. But he takes a different approach than most other Professors—instead of handing you a starter Pokémon, he gives you Poké Balls so you can catch your first one yourself. It's a pretty fitting twist for a game that's all about getting out there and catching wild Pokémon.
