Dr. Poppeliers Publishes Paper
Dr. Christian Poppeliers, Associate Professor of Physics, has just published a paper entitled "Multiwavelet Seismic-Wave Gradiometry" in the October 2011 issue of the Bulletin of the Seismological Society of America. The paper describes a method to derive formal uncertainty estimates on measured seismic wave speed, direction, and geometrical spreading, all as a function of time. According to Dr. Poppeliers, “this has never really been done before, and has applications to earthquake engineering”. That is “when building a structure in a seismogenic zone (e.g. San Francisco), we can use earthquake data to determine the site's response to seismic waves. This is important because not all sites shake equally. Using some of the methods in this paper, a structure can be designed to withstand the shaking that's specific to that site”.

Congratulations to Dr. Poppeliers on publishing this research!
