Input: Question: In which county is the school where Gordon earned his Ph.D. located? Passage:A Seattle native, Gordon exhibited an early interest in theoretical physics, especially quantum mechanics and the theory of relativity. His childhood heroes were Albert Einstein, Stephen Hawking, and Richard Feynman. After observing a series of teleportation experiments conducted by the Institute for Experimental Physics at the University of Innsbruck, the transmission of matter became Gordon's obsession. Gordon has no known dependents. He graduated from the Massachusetts Institute of Technology with a Ph.D. degree in Theoretical Physics. His doctoral thesis on the teleportation of matter through extremely dense elements was titled Observation of Einstein-Podolsky-Rosen Entanglement on Supraquantum Structures by Induction Through Nonlinear Transuranic Crystal of Extremely Long Wavelength (ELW) Pulse from Mode-Locked Source Array. Gordon's research into science eventually led him to accept a job offer by the Black Mesa Research Facility, and begin working on a top-secret research project headed by his mentor at MIT, Dr. Isaac Kleiner. He takes up residence at Black Mesa, conducting nuclear and subatomic research in its Anomalous Materials department. Despite his education as a theoretical physicist, the work Freeman is involved with at Black Mesa is of a more experimental nature.
