Biography

Gregory H. Ogin was born in 1982 in Kailua-Kona, on the Big Island of Hawaii. He graduated from Konawaena High School in June 1999. He is currently an undergraduate student at the University of St. Thomas in St. Paul, Minnesota, where he is pursuing degrees in Physics, Mathematics, and Electrical Engineering. Some day he even plans on graduating, after which he will likely pursue a Ph.D. in physics. Greg enjoys taking physics/math/EE classes, although he dislikes homework just as fervently as the next person. Some of his other hobbies include playing tennis (he's on the university's Division III tennis team), and playing classical piano. His all-time favorite composer is Chopin. Greg's work experience includes lots of math and physics tutoring, as well as the design and synthesis of a small, cost-efficient high voltage power source for low current applications (e.g. electron beam optics).
