 Jorge Quijano, a PhD candidate at the ECE department, has been awarded a Graduate Traineeship Award by the Office of Naval Research to support his ongoing research on Ocean Bottom Scattering at mid-frequencies. This research is of great interest for navy sonar applications in shallow water, because the interaction of acoustic energy with the ocean bottom results in high levels of reverberation noise that can diminish the performance of current sonar systems. It is also applicable to the more general problem of monitoring the ocean environment with emphasis on classification of ocean bottom sediments and layers. Jorge's research is helping to develop more accurate models to increase our understanding of acoustic wave propagation and interaction with very complex media such as ocean bottom sediments.
Jorge arrived at Portland State University in 2004 as a Fulbright scholar to pursue a MS degree on Electrical and Computer Engineering. He joined the Northwest Electromagnetics and Acoustics Research Laboratory (NEAR-Lab) in 2005 and worked on signal processing for sonar applications in shallow water using the Bistatic Invariance Principle, a new target tracking technique that exploits temporal and frequency structure in propagating waves.
In 2006 Jorge started with his PhD program and he was invited to participate in the Navy sponsored Shallow Water 2006 (SW06) Experiment as part of the team aboard the Research Vessel Knorr (operated by MIT Woods Hole Oceanographic Institute). The experiment was conducted off the eastern coast of the United States, and it provided high quality data on ocean bottom acoustic scattering. This experimental data, in addition to laboratory tank experiments conducted in the new NEAR-Lab Measurement Facility, will support Jorge's PhD research.
Jorge Quijano is currently a student member of the Acoustical Society of America (ASA) and a member of the Organizing Committee for the Portland ASA meeting to be held on May 2009. He was recently selected Outstanding ECE PhD student in 2008, and he is the author of several papers and presentations in ASA and IEEE Oceans meetings. The ONR Graduate Traineeship Award is a prestigious award given only to a few of the best graduate students nationwide, and it reflects the excellent research work done by Jorge.
