The PDA provides the proper information: there are several 'Doctor Gina Babette Diggers' registered in various fields of science all over the United States, as professors, assistants and the like (and surely enough, they are all Alternates of the same girl) but the top story in Google is the visit of the CEO of Diggers Technologies, Dr. Gina Babette Diggers, to Seattle.
Diggers Technologies is one of the many meta-corporations in Coreline, seling all kinds of technology for 'adventuring' and 'defense' for anybody from Spelunkers to the United Stated Armed Forces. Their trademark, so to speak, was in creating firepower that in any other circumstance but the current way of things would be considered 'overkill'.
Fully-automatic mini-rocket launchers, two-story-tall tanks, armor for EOD units capable of taking point-blank near-nuclear explosions... for starters.
