Matthias loves beetles. And almost as much as he loves beetles he is fascinated with nematodes. His work focuses on scarab-inhabiting nematodes, which sounds unpleasant but turns out to be a real thriller!
He can tell you wonderful stories about necromenic worms in scarabs.
If you want to make Matt REALLY happy, send him living or recently dead scarabs from all over the world, so that he can screen them for nematodes. He might even name a new nematode species after you!!!
