U-M researchers Anna GilbertMartin Strauss, and Joel Tropp have won the 2010 Signal Processing Best Paper Award from the European Association for Signal Processing (EURASIP). This award is given to a paper published in the previous four years in the EURASIP Journal of Signal Processing.

The paper, entitled “Algorithms for simultaneous sparse approximation. Part I: Greedy pursuit,” was published in Signal Processing, Volume 86, Issue 3, March 2006. The work was done when all three researchers were at U-M. (Tropp was then an assistant professor in Mathematics at U-M; he is now an assistant professor at California Institute of Technology).

The award will be given at the Conference Banquet of the 18th EUSIPCO Conference, which will be held on August 23-27 2010, in Aalborg, Denmark.

Anna Gilbert is an Associate Professor of Mathematics and Electrical Engineering and Computer Science. Her research interests include analysis, probability, networking, and algorithms. She is especially interested in randomized algorithms with applications to harmonic analysis, signal and image processing, networking, and massive data sets.

Martin Strauss is an Associate Professor of Mathematics and Electrical Engineering and Computer Science. HIs research interests include fundamental algorithms, especially randomized and approximation algorithms; algorithms for massive data sets; signal processing and and computational harmonic analysis; computer security and cryptography; and complexity theory.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
