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.

Current Research and Scholarly InterestsBiographical Information
Jerry M. Harris is the Cecil and Ida Green Professor of Geophysics and Associate Dean for the Office of Multicultural Affairs. He joined Stanford in 1988 following 11 years in private industry. He served five years as Geophysics department chair, was the Founding Director of the Stanford Center for Computational Earth and Environmental Science (CEES), and co-launched Stanford's Global Climate and Energy Project (GCEP). Graduates from Jerry's research group, the Stanford Wave Physics Lab, work in private industry, government labs, and universities.
My research interests address the physics and dynamics of seismic and electromagnetic waves in complex media. My approach to these problems includes theory, numerical simulation, laboratory methods, and the analysis of field data. My group, collectively known as the Stanford Wave Physics Laboratory, specializes on high frequency borehole methods and low frequency labratory methods. We apply this research to the characterization and monitoring of petroleum and CO2 storage reservoirs.
I teach courses on waves phenomena for borehole geophysics and tomography. I recently introduced and co-taught a new course on computational geosciences.
I was the First Vice President of the Society of Exploration Geophysicists in 2003-04, and have served as the Distinguished Lecturer for the SPE, SEG, and AAPG.
