Students of exceptional ability as demonstrated by previous academic achievement may pursue a program leading to the doctoral degree. The prospective doctoral candidate in Earth and environmental science with specialization in physics of the solid Earth should develop a solid background in physics, mathematcis, and geology in addition to achieving a high level of competence in the field of geophysics. With the approval of the advisory committee, the student should select a program including a minimum of nine credit hours in graduate geophysics beyond the M.S. degree, three credit hours of GEOP 592, at least four
credit hours of GEOP 593, unless the degree is completed in a shorter time, plus additional courses in related fields. Research fields appropriate for the geophysics candidate include crustal exploration, earthquake seismology, tectonophysics, environmental, and hydrogeothermal studies. Interdisciplinary programs in the Earth science fields are encouraged.
