Current Research and Scholarly InterestsElizabeth Hadly and her lab probe how perturbations such as climatic change and human modification of the environment influence the evolution and ecology of animals.
Ph.D. Student in Geological Sciences
BioI am a PhD student interested in the quantification of subsurface uncertainty, with four years of experience at Freeport-McMoRan's copper mine at Bagdad, Arizona.
In the context of mineral exploration, how can we determine the priority of data collection? The ultimate goal is to make a discovery, but often our datasets contain significant bias, which needs to be addressed. It may be that we need to collect data in areas that we know do not contain a mineral deposit, but will still add value to our models. Where do we collect this "negative" data, and how can we make sure we only collect as much data as necessary?
Due to the deterministic nature of some spatial interpolation (inverse distance weighting, nearest neighbor, splines), exploration datasets also contain bias introduced during interpolation. What sampling density do we need to reasonably apply these common techniques? When does it make more sense to use kriging or SGSIM?
Measuring uncertainty often involves Monte Carlo, which is computationally expensive. Intelligently deploying computational resources relies on addressing the underlying assumptions of our data, and aligning our goals with "reasonable" conclusions.

Visiting Scholar, Department of Geological Sciences
BioI am broadly interested in regional tectonics, crustal evolution, global paleogeography, and the nature of orogenesis. My research is informed by a variety of techniques, including structural geology, mapping (i.e. spatial data visualization), geochronology, metamorphic petrology, thermochronology, thermobarometry, isotope geochemistry, and geophysical datasets.
In the western US Cordillera, my research focuses on the interplay between crustal thickening, geothermal gradients, magmatism, and extension in the orogenic hinterland. Much of this work has centered around field studies in the northern Snake Range metamorphic core complex of Nevada, which offers a unique glimpse as to processes operative in the upper, middle, and lower crust during mountain building.
In the Alaskan Cordillera, my research focuses on the long-term paleogeographic and tectonic evolution of the northernmost Cordillera (Brooks Range and Arctic Alaska). One such effort is an attempt to better understand a major post-Caledonian plate reorganization that led to subduction initiation on the then-passive Laurussian margin, followed by backarc rifting and translation of "exotic" crustal terranes southward into the western US Cordillera.
Masters Student in Geological Sciences
BioI've had an interest in rocks and fossils since I was a small child, amassing a large collection in my youth, but hadn't considered it a viable career path instead starting my path as a social scientist studying gender and sexuality. My interest in a career in paleontology peaked after finishing my first degree, leading me to pursue a second bachelors degree. While working on my undergraduate at Weber State I discovered a true deep love of plants as well as a curiosity about the methods they use to adapt to new environments, which has lead me to pursuing a Masters degree here at Stanford University.
