  • Andrew Luhmann (Assistant Professor of Hydrology), Susan Bilek (Professor of Geophysics), and Ronni Grapenthin (Assistant Professor of Geophysics) received an NSF grant to study geophysical responses during recharge events in a karst aquifer. Two graduate students who are interested in hydrology, geophysics, and karst will ideally start in Summer 2018. Please click here for more information

Glenn Spinelli, Department Chair

Welcome! Earth and Environmental Science is a leading department at New Mexico Tech with a prominent international profile for Earth science research. We strive for excellence in conducting important and cutting edge research across the sub-disciplines of Geology, Geochemistry, Geophysics, and Hydrology. Our research strengths extend from Earth’s deep interior to its shallow crust and surface. The Earth and Environmental Science Department is acutely aware of the relationship of its work to many issues of critical concern to society as a whole, and endeavors to interact with the broader community at the local, state, national, and international levels to disseminate knowledge bearing on these societal concerns.Donate_logo

We are devoted to the education of future generations of Earth scientists and introducing them to the wide array of excellent careers within the field. We educate graduate students to become leaders in academia and industry. We seek engaging means for undergraduate education, preparing students for societally-relevant and fulfilling careers.

PetroFieldTripJemezNew Mexico Tech’s Department of Earth and Environmental Science offers BS, MS, and PhD degrees in a broad range of earth sciences. The department incorporates five strongly interacting graduate programs — Geology, Geochemistry, Geophysics, Hydrology, and Geobiology — in association with an integrated undergraduate major in Earth Science featuring options in Geology, Geophysics, Hydrology, and Mineral Resources. The department also administers a cross-department undergraduate degree in Environmental Science.

The department has 14 faculty members, of which four are in geophysics, five in hydrology, and five in geology/geochemistry. In addition, the department has more than 40 affiliated research and adjunct faculty who are actively involved in research and/or teaching. Many of these are from the New Mexico Bureau of Geology and Mineral Resources, which is located on campus, but they also come from national laboratories, industry, and other organizations. The IRIS PASSCAL Instrument Center and EarthScope USArray Array Operations Facility, two major NSF-funded seismological facilities, are also housed on campus and administered by faculty of the geophysics program.

The department maintains an average of 65 graduate students and 60 undergraduate students and is strongly research-oriented. Major areas of research include (but are not restricted to):


Research is strongly interdisciplinary and there is extensive cooperative research between programs. Major research instrumentation and facilities include well-equipped research computing laboratories, 40Ar/39Ar, quadrupole, and stable isotope mass spectrometers, electron microprobe, high-pressure rock physics and rock mechanics laboratory, fission track and image analysis lab, neutron activation counting lab, liquid and gas chromatography lab, a flow visualization lab, and local seismic networks.

Faculty research productivity is high, with external funding currently at about $7 million per year. Undergraduate as well as graduate students are involved in research activities.
