:: Research Interests ::
My research utilizes fundamentals of physics, mathematics, geology, and computer science to learn about how the Earth deforms in response to tectonic stresses. Currently, I am most interested in the physics that governs how faults work and how we can measure deformation of the Earth's surface using satellite geodesy techniques (GPS/InSAR). Because this type of work is quantitative and involves processing very large data sets, computer programming is a key component to my research. If you are a student and this type of research sounds interesting, please see my student opportunities page.

5.04.2012 :: Poster-sized earthquake epicenter maps are now available for download in the
student opportunities section. I currently have three maps available for download.
1) Eastern United States Earthquakes 1972-2012 :: PDF (42.5" x 42", 103 Mb)
2) Northern California Seismicity 1984-2003 :: PDF (42"x44.5" 133Mb)
3) Southern California Seismicity 1981-2005 :: PDF (49"x42" 95Mb)
The maps are all 42" in their smallest dimension, so they will print nicely on a 42" plotter. I have downsampled the DEM data to make the file sizes considerably smaller than the original postings. Feel free to download the PDF's and distribute to anyone that may be interested, but please provide the proper attribution. They make great teaching tools!
8.23.2011 :: Earthquake in Virginia!! We felt it here in Boone. I posted a Q&A page with some commonly asked questions and my responses on our department webpage. The university news folks also interviewed me and posted an article about the earthquake.
8.22.2011 :: I have added a description of my work with Julia Irizarry, a undergraduate student in the department of geology. Julia is using mathematical models of faults to determine if the 1994 M6.7 Northridge could have triggered deep aseismic slip on the San Andreas fault. Check it out!
10.05.2010 :: I have added a description of my work with Bevin Bailey, a undergraduate student in the department of geology. Bevin is using several near-surface field geophysical techniques to characterize a local aquifer. Her geophysical data will be complimented by data from nearby boreholes. Check it out!
5.20.2010 :: I have added a description of my work with Anna Morris, a graduate student in the department of physics. We are modeling the mechanics of non-planar wavy fault surfaces. Check it out!
5.10.2009 :: I posted large-format maps of California seismicity on my student opportunities page. The files are rather large, but the maps are fantastic. Check them out!
10.1.2008 :: If you have any general website suggestions, or if you find things that don't work, email me!
