Dr. John Dvorak received his PhD in planetary geophysics in 1979 from the California Institute of Technology in Pasadena, California. That was followed by 16 years working for the U.S. Geological Survey on earthquakes and volcanoes, including the 1980 eruption of Mount St. Helens and eruptions in Hawaii, Alaska, Italy, Central America and Indonesia. Currently, he operates one of the large telescopes at the summit of Mauna Kea in Hawaii. His professional interests are far ranging, including earthquakes and volcanoes, as well as the flaring of comets, what scientific evidence there may be for life outside the solar system, and whether the multiverse can ever be proven to exist.
