Environmental Geology

Mapping of geologic features and hazards using tools including traditional field measurements, GPS and GIS, and remote sensing.

Engineering Geology & Geological Engineering

Our research in this focus area combines three distinct areas of interrelated fields of research exploring novel, effective and accurate methods to improve the geo-engineering process: mapping, testing/characterization, and design.

Engineering Geophysics

Our research in this focus area primarily seeks to improve field surveying and data interpretation methods of active and passive seismic exploration.

Ichnology of Continental Environments

Our research involves the study of trace fossils in ancient continental environments as informed by neoichnological research in laboratory and modern continental field settings. Methods employed include traditional field and lab observations, GPR, soil coring, petrography, and 3D laser scanning.

Trace metal Geochemistry, Environmental isotopes, Bio-mineralization and environmental Mineralogy

Our research goals intersect among trace metal geochemistry/isotope geochemistry and bio-geochemistry of environments. Our goal as scientists is to investigate how the microbial world affects and drives metal cycling in both modern and ancient environments.
