Claudia's a computer whiz and a hardcore physicist who dabbles in chemistry. Which means that she can a) hack into various servers, b) research the hell out of stuff that can be found on the internet, c) crack door codes and things given time and a computer terminal to connect to said electronic door code, and best of all, d) build crazy-ass crap out of whatever she finds lying around.

She can probably repair your high-tech devices, as well. Though she'll want permission to mess with them a bit before she returns them.
