Atoms and molecules, basically Hope's bread and butter - she lived and breathed nanotech, and those subatomic particles. Whatever work she could get done studying the Quantum Realm, all the better. The fact that Tony Stark offered her a place to set up shop after she found herself in this flippy, broken-time sort of universe, would help with that. Having a space to work, quietly, was ideal for any scientist.
And this was her calling. As she grew up, her science drive had kind of been killed so she erred more on the side of business, but she still missed her work at Pym Tech, which had unfortunately been a victim of scorched earth policy - burn it all down, for the good of the people - thanks to the nutjob that was Cross; she was glad to have a chance to continue here while also fighting the good fight. And protecting others too, following in her mother's footsteps.
She'd do an inventory and take stock of what she needed - pore size analyzers, the right kind of microscopes, things like that - but for this introduction, she brought her Wasp suit and other accessories for the purposes of demonstrations. "Tony," she greeted, tightening her ponytail as she entered the lab. "Nice to meet you in person, officially."
