Our state-of-the-art laboratory facilities allow our faculty to push the boundaries of their fields and give our students the chance to do their own research. We apply geology, mineralogy, petrology, biology, chemistry, physics, and math to investigate diverse topics such as early life on Earth, the structure of Earth's deep interior, the nature of contaminant transport, and the evidence for water on Mars. Our alumni are uniquely poised to help solve some of society's most pressing problems through careers in government, non-profit organizations, academia, and industry.
