In the morning of August 21, the 2015 JIE students had their first lecture in JIE building, just before the Inauguration Ceremony of Sun Yat-sen University.
The lecture was given by Professor Yuanwei Jin from University of Maryland and hosted by Ming Li, Assistant Professor of JIE. The topic was Large Scale Computational Inverse Problems for Big Data Imaging. In the lecture, Professor Jin talked about imaging with acoustic waves by solving the inverse problems of acoustic wave propagation.
Imaging with acoustic waves has played a major role in many critical applications, such as nondestructive inspection of large scale infrastructure and seismic exploration of oil and gas. Acoustic waves that interact strongly with sophisticated medium have complex characteristics and are difficult to model. Jin introduced the Multi-In-Multi-Out Propagation and Backpropagation method to efficiently solve the nonlinear inverse problem in wave propagation modeling in high resolution ultrasonic tomography. Jin also introduced the use of modern graphics processing units (GPU) to address the computational challenges in the presence of large data for large-scale inverse problems.
After the talk, the students had a warm Q&A with Professor Jin.
Professor Jin is an Associate Professor of Electrical Engineering with the Department of Engineering and Aviation Sciences of the University of Maryland, Eastern Shore. His research interests are in the general area of signal processing, sensor array processing, and computational inverse problems, with applications in radar/sonar, communications, biomedical imaging, and structural health monitoring. He has received many awards for outstanding academic achievement, including a 2010 Air Force Summer Faculty Fellowship award and an Earle C. Anthony Fellowship from the University of California at Davis.
