Research Activities:

Dr. Cox specializes in Geotechnical Engineering issues related to earthquake loading, soil dynamics and nondestructive material characterization using stress waves. He has been a part of the Geotechnical Extreme Events Reconnaissance (GEER) teams deployed immediately following the M7.1 Darfield, New Zealand Earthquake, the M7.0 2010 Haiti Earthquake, the M6.9 2008 Iwate-Miyagi, Japan Earthquake and the M8.0 2007 Pisco, Peru Earthquake. He has also been a part of teams deployed to collect shear wave velocity data at strong motion stations and soil liquefaction sites following the 2011 Tohoku, Japan Earthquake, the 2011 Christchurch, New Zealand Earthquake, the 2006 Kiholo Bay, Hawaii Earthquake, the 2001 Nisqually (Seattle), Washington Earthquake, and the 1999 Kocaeli, Turkey Earthquake. Additionally, Dr. Cox has been involved with numerous dynamic site characterization projects where crosshole, downhole and surface wave techniques were employed for the seismic design of critical government facilities such as the Yucca Mountain Project, the Device Assembly Facility (Nevada Test Site), the DOE Hanford Site, the Y-12 National Security Complex, Oak Ridge National Laboratory, and Los Alamos National Laboratory.

In 2011, Dr. Cox received the prestigious Faculty Early Career Development (CAREER) award from the National Science Foundation for his work on quantifying uncertainty in surface wave methods used for non-intrusive geotechnical site investigations. He operates a Vibroseis shaker truck ('The Hawg') as part of his earthquake and dynamic material characterization research. His Ph.D. graduate research centered around the development of a new in-situ test method for directly measuring the dynamic pore pressure response and nonlinear shear modulus behavior of liquefiable soil deposits. For this research, he was selected as the 2004-2005 FEMA Graduate Fellow in Earthquake Hazard Reduction by the Earthquake Engineering Research Institute (EERI).

In 2010, his work in this area was recognized by the ASTM Geotechnical Testing Journal through receipt of the Hogentogler Award for his "paper of outstanding merit." He is a member of the American Society of Civil Engineers (ASCE), GEER, EERI, and the Arkansas Governor's Earthquake Advisory Council (AGEAC).
