The thesis is a structural and petrographic study of approximately
23 square miles in the Millican SE quadrangle, Deschutes
County, Oregon. The area lies along the Brothers fault zone.
Bedrock in the area is of Pliocene to Recent age and consists
of an older basaltic unit with an associated dacite,...

NASA’s ICESat-2 satellite, which launched in 2018, carries the Advanced Topographic Laser Altimeter System (ATLAS), a green-wavelength, photon-counting lidar. While ICESat-2’s primary mission focuses on measurement of elevation of ice sheets, glaciers, sea ice, and vegetation, ATLAS has also proven remarkably effective at measurement of bathymetry, or water depths. However,...
Substantial investments in fuel management activities on national forests in the western US are part of a
national strategy to reduce human and ecological losses from catastrophic wildfire and create fire
resilient landscapes. Prioritizing these investments within and among national forests remains a challenge,
partly because a comprehensive assessment that...

What is the nature of evolutionary divergence of the jaw skeleton within the genus Oncorhynchus? How can two associated bones evolve new shapes and still maintain functional integration? Here, we introduce and test a ‘concordance’ hypothesis, in which an extraordinary matching of the evolutionary shape changes of the dentary and...

"What’s wrong with this AI?" Explainable AI (XAI) researchers are moving beyond explaining an AI’s actions, to helping users detect an AI’s failures. However this detection may not be enough—for actionability, we often need to pinpoint which part failed. We investigate how AAR/AI, a structured assessment process, supports users with...

Marine diseases are becoming more frequent, and tools for identifying pathogens and disease

provides insights into disease etiology by cataloguing and comparing sequences from suspected
pathogens. This method is a powerful approach to simultaneously evaluate both the
viral and bacterial...

Feedback loops involving soil microorganisms can

Mundane goods such as pottery are particularly under-studied, and owing to...
1. Spatial climate variables are routinely used in species distribution models (SDMs) without accounting for the
fact that they have been predicted with uncertainty, which can lead to biased estimates, erroneous inference and
poor performances when predicting to new settings – for example under climate change scenarios.
