Research
I am currently an Ph.D. candidate working in the Active Tectonics Research Group in the School of Earth and Space Exploration (formerly Geological Sciences) at ASU, my research interests broadly include tectonic geomorphology, paleoseismology and geoinformatics. Information on my research and relevant links can be found below.
Ph.D. RESEARCH AT ARIZONA STATE UNIVERSITY:
Much of my Ph.D. research at this point is an outgrowth of projects that I began or were involved with during my M.S. The following projects are currently active and I expect them to develop and evolve as my Ph.D. matures:
Geoinformatics:
- Development of the next generation GEON LiDAR Workflow as a production quality resource for the geoscience community. Expansion of the GLW to include remotely sensed data integration with high-resolution topography.
- Exploiting LiDAR for Regional Morphologic Correlation and Dating of Wave-cut and Fault-Controlled Landforms
- Active tectonics and characterization of large thrust faulting earthquakes in the Northern Tien Shan, Kyrgyzstan
M.S. RESEARCH AT ARIZONA STATE UNIVERSITY:
Using web services, high-performance databases, the Kepler Scientific Workflow System and GRASS Open Source GIS, we have built an online tool set that offers distribution of LiDAR / ALSM point cloud data, interpolation to grid (DEM) as well as calculation of a variety of derived products - the GEON LiDAR Workflow (GLW). The GLW is a product of collaboration between the Active Tectonics Research Group at ASU and colleagues at the San Diego Supercomputer Center as part of the GEON project. The goal of this project is to make available an interactive system for data distribution and processing (gridding/interpolation) of LiDAR point cloud data that leaves the heavy processing to the distributed computational resources available through the GEON Grid. Ultimately, we hope that this tool will democratize access to these very powerful data sets.

OTHER PROJECTS - In addition to the geoinformatics component of my thesis research discussed above, I was also involved in the following projects during my M.S.:
- Exploiting LiDAR for Regional Morphologic Correlation and Dating of Wave-cut and Fault-Controlled Landforms
- Active Tectonics of the Northern Tien Shan, Kyrgyzstan - Field work and GIS
- Kilometer-scale San Andreas Fault zone structure at Parkfield, CA - Paleoseismology and GIS

B.S. RESEARCH AT WHITMAN COLLEGE
As an undergrad at Whitman College, I was fortunate to work on two different projects. The first project was conducted as an independent study with Dr. Bob Carson and was related to the Pleistocene history of Steamboat Rock in the Grand Coulee, WA. This work resulted in a paper published in Washington Geology:

Crosby, C.J., and Carson, R.J., 1999, The Geology of Steamboat Rock, Grand Coulee, WA: Washington Geology, vol. 27, no. 2/3/4, p. 3-8.
My senior thesis research work grew out of a Keck Geology Consortium undergraduate research project on the northern California coast. My research was advised primarily by Dr. Carol Prentice of the U.S. Geological Survey in Menlo Park, CA and Dr. Kevin Pogue and focused on paleoseismology of the northern San Andreas fault:
