Research Appointments
2016-Present Postdoctoral Researcher -- University of Washington
ICESat-2 altimetry and NASA IceBridge data interpretation - Advisor: Knut Christianson
This work, funded through NASA grant NNX16AM01G, is designed to identify hypotheses testable using data from ICESat-2 upon launch. This means identifying locations of expected detectable thickness change and compiling historic ice-sheet elevation records from IceBridge, Cryosat2, ICESat, and WorldView data. Additionally, we are funded to continue interpretation of IceBridge ice penetrating radar data, using new swath imaging methods to create more spatially comprehensive ice-thickness maps.
2012-16 NSF Graduate Research Fellow - Pennsylvania State University
2011-12 University Graduate Fellow - Pennsylvania State University
Ph.D. work in glaciology - Advisors: Richard Alley and Sridhar Anandakrishnan
My Ph.D. research focused on improved data processing and interpretation for radar data collected in Antarctica and Greenland. As we move toward more quantitative interpretation of radar reflection amplitudes, it is important that we identify all of the sources of power variability introduced both by physical processes and as an artifact of the imaging process. My attempted to identify and isolate several of these controls, and develop new automated methods for quantitative description of the data. The end goal of this research is to develop products that can be used to constrain ice-sheet models.
2014,15 Graduate Research Intern - Chevron Energy and Technology Company
Improving Time Shift Methods for 4D Seismic Data Analysis - Advisor: Larry Sydora
Over two summers, I conducted research into 4D seismic processing techniques, with a focus on time-shift analysis and acoustic impedance inversion. Seismic time lapse data has the potential to inform production schedules and practices for industry, but there remains potential to improve processing algorithms to produce a cleaner interpretation product. The team I worked with is developing novel processing methods to help determine acoustic impedance changes in the subsurface during hydrocarbon extraction. This work led to a patent.
2010-11 Research Fellow - Pacific Tsunami Warning Center
Investigating the role of Fault Geometry on Tsunamigenesis - Advisor: Gerard Fryer
The role of the Pacific Tsunami Warning Center (PTWC) is to provide real time monitoring of earthquakes, and evaluate the tsunami generation potential of seismic events in the Pacific. This has historically been done using models which approximate the size, shape, and orientation of the fault plane based on magnitude and location of the earthquake, assuming all earthquakes occur at the depth of plate boundary, on the decollement, and have a reverse sense of motion. My job was to evaluate a numerically simple, but fully customizable tsunami model against historic data, to determine if the simple model would be useful for active warning despite the numerical simplifications. I also tested the models sensitivity to different fault orientations. This research was funded by the Ernest F. Hollings Scholarship Program.
2008-11 Research Assisstant - Carleton College Departments of Geology and Economics
Land Pricing (Advisor: Aaron Swoboda), Water Quality (Advisor: Bereket Haileab) \, and Paleomagnetics (Advisor: Sarah Titus)
(1) Helped develop a spatial autoregression package in R to determine the real value of land using house prices from California. (2) I developed and conducted a seasonal survey of the surface water chemistry of Rice County, MN, over 5 seasons. The objective was to see the spatial and temporal variation of contaminants in the surface water. I collected the samples, analyzed the water using alkalinity titrations and ion chromatography, and performed statistical analysis of the data in ArcGIS. (3) Assisted in the statistical analysis of paleomagnetic data collected in Southern California.
