Rob McCaffrey
Professor of Department of Earth and Environmental Sciences
Rensselaer Polytechnic Institute

Education:
Ph.D., Geophysics, University of California, Santa Cruz, 1981
B.S., Geophysics, Boston College, 1976


Career Highlights:

McCaffrey began his professional career in 1982 at the Massachusetts Institute of Technology, first as a postdoctoral research associate and later as a research scientist. While at MIT, he also spent two years as an Air Force Geophysics Scholar for the Air Force Geophysics Laboratory. McCaffrey joined Rensselaer in 1988 as an assistant professor and served for three years as chair of the Department of Earth and Environmental Sciences. He spent a year as a visiting associate professor for Oregon State University in 1995 and as a visiting professor at the Ecole Normale Supérieure - Paris in 2001. McCaffrey was promoted to professor in 1999.

McCaffrey has been invited to give several keynote lectures for such events as the German-American Frontiers of Science symposium in Potsdam (1999), the Penrose Conference on Subduction to Strike-slip transitions in the Dominican Republic (1999), the Tectonic Evolution of Southeast Asia Symposium in London (1994), and the Snellius II Symposium in Jakarta, Indonesia (1987). He speaks Indonesian and some French and is a member of the American Geophysical Union (AGU).

Research Areas:
McCaffrey's research interests include the analysis of geological, seismological, gravity, and geodetic data from convergent margins with attention to the structure, tectonics, and dynamics of subduction and collision. Most of these applications involve inversions; McCaffrey has developed methods specifically in earthquake waveform and crustal deformation inversions.

His work involves studying the impact of oblique convergence on subduction zone deformation to determine the reasons some deformations result in great earthquakes and others do not. McCaffrey uses teleseismic body waves and microearthquake networks to constrain the depths and mechanisms of earthquakes in order to understand variations with depth of arc-continent and arc-arc collision processes.

McCaffrey has studied the source processes of large Australian earthquakes, used slip vectors at oblique subduction zones to constrain the deformation rates and rheology of forearcs, and used Global Positioning System (GPS) to measure crustal deformation. He has conducted GPS measurements in Oregon, Indonesia, and Papua New Guinea; deployed equipment through the Program for the Array Seismic Studies of the Continental Lithosphere (PASSCAL) and Rapid Array Mobilization Plan (RAMP) in Indonesia, and performed microearthquake surveys in Northern Utah, Papua New Guinea, the Molucca Sea, and Indonesia.

McCaffrey's current projects include analyzing thermal properties of subduction zones and their relationship to seismicity; observing and modeling the deformation of forearcs at subduction zones and of Southern Tibet as a response to oblique convergence, and studying aftershocks and coseismic displacements from the February 1996 Irian earthquake in Indonesia. He collaborates with such organizations as the University of Washington, Scripps Institution of Oceanography, and BAKOSURTANAL, Indonesia's national coordinating agency for surveys and mapping.
