He's a research assistant at a new Pokémon lab set up in Kanto and seeing as he's being sent to investigate a swarm of Ivysaur in the town the lab's in (it seems they're on a pilgramige to evolve, like back in OG series had the episode his Bulbasaur refused to evolve), I'd say his reasonings for visiting the other regions is to study some happening with some indiginous species, though they did remark on how he wants to further his dream of being a pokémon master still, so I'd say at least he'll get involved with a fair few battles along the way.
