Teaching
At Appalachian State, I teach Structural Geology and Tectoncis (GLY 3150), Environmental Geology (GLY 1103), Senior Seminar (GLY 4210) and various intro labs. Students can access material for these classes through the Appalachian WebCT page.

Research Interests
How do mountains grow? Using neotectonics, paleoseismology and geomorphology, I am interested in how the crust accommodates and sheds tectonic stresses. To explore these areas, I have focused my field efforts in two topics:

PALEOSEISMOLOGY OF THE SAN ANDREAS FAULT
Working with Ray Weldon (UO), Tom Fumal (USGS) and Glenn Biasi (UNR), we have trenched, documented, and dated at least 28 earthquakes that occurred between ~3000 and 1500 BC and AD 1500 to present near Wrightwood, CA. These results are published in BSSA and implications for these results are examined in other journals (see below); In 2006 we began new searches for great paleoseismic sites in the relatively unexplored Northern Big Bend stretch of the fault near Tejon Pass.

NEOTECTONICS OF THE TIAN SHAN (MOUNTAINS)
Using structural mapping, geomorphic surveys, and paleomagnetic dating, I have worked to understand the last ~1.5 My of folding exhibited on the southwest margin of the Tian Shan. My colleagues Doug Burbank (UCSB), Chen Jie (CSB), and Dick Heermance and I are working on a refined understanding of the development of the Kashi fold (in review); previous papers can be accessed on from the publication list below. That's me in the photo at right, walking into a slot canyon cut through the ~1Ma Xiyu conglomerate. Fortunately, no rain that day!


Evolving out of my move to an ancient range, the Appalachians, I am starting a local project to research debris flows. I plan to investigate the time span and dimensions of colluvial hollows in the Blue Ridge. With luck and lots of digging, I hope to tie the hollows to the depositional areas through dating and detailed mapping in order to assess magnitude/frequency relationships for this rapidly developing region.
