Current Research projects: 

1. Quantifying rock strength from river channel morphology

The goal of the study is to develop this quantitative framework by combining field and laboratory experiments with the advancement of theory to understand how bedrock channel morphology reflects the geotechnical properties of the material the river flows over. The goal of the study is to quantitatively predict how channel morphology reflects rock strength in our study area and beyond.  Specifically, we will make predictions, rooted in theory and validated with measurements, of how channel slope and width vary with geotechnical properties such that remote observations of channel morphology can provide insight into the material properties underlying a landscape.

2. Development and Evaluation of Performance Measures to Augment Asphalt Mix Design in Idaho

The Superpave volumetric mix design is conducted without performance criteria to evaluate the mix resistance to cracking (fatigue and low temperature), rutting and moisture damage. The current tests used by various transportation agencies to evaluate cracking, rutting, and moisture damage of asphalt mixtures will be reviewed.
