Prof. Richard Baraniuk of the Rice DSP/Machine Learning group has two open postdoc positions for research in machine learning theory and methods, computational sensing/imaging, and sparse signal processing. The Rice University offers an energizing environment for research; 18 recent postdocs have been placed in top faculty positions at Columbia, Cornell, CMU, Georgia Tech, Univ. Michigan, Univ. Maryland, Univ. Wisconsin, Univ. Minnesota, UMass-Amherst, EPFL, and INRIA.  More information soon on the application procedure.

Rice Assistant Professor Anshumali Shrivastava has received an NSF CAREER award for his project "Hashing and Sketching Algorithms for Resource-Frugal Machine Learning." The project will develop new probabilistic hashing techniques to advance state-of-the-art machine learning algorithms. Apart from being exponentially cheaper, the new algorithms will also be massively parallelizable. The project capitalizes on several recent ideas, including asymmetric hashing, hash-based kernels, densified hashing schemes, sub-linear adaptive sampling, and adaptive sketching, to push learning algorithms to the extreme-scale.

Rice Assistant Professor Ashok Veeraraghavan has received an NSF CAREER award for his project "A Signal Processing Framework for Computational Imaging: From Theory to Applications." The project will develop a signal processing framework to develop new imaging systems that see deeper into nature with enhanced microscopes and farther out through consumer cameras for bio-medical, remote sensing, machine vision, and surveillance applications. Since joining Rice from MERL in 2010, Ashok has made his mark at the university through his lab’s development of mobileVision, a simple device to monitor eye health, and FlatCam, a lens-less camera platform project with colleague Richard Baraniuk. Ashok has also been promoted to Associate Professor with tenure, effective July 2017.

DSP alum Christoph Studer (postdoc 2010-2012, Assistant Professor at Cornell University) has received an NSF CAREER award for his project "Hardware Accelerated Bayesian Inference via Approximate Message Passing: A Bottom-Up Approach." The project will bridge the ever-growing gap between theory and practice in Bayesian signal processing using a holistic approach that spans the circuit design, algorithm, and theory levels. In addition to improving the efficiency and quality of Bayesian inference in real-time applications, the project will advance future wireless systems through collaboration with the telecommunications industry, along with the development of new tools that are accessible to experts on all levels.

DSP group alum Aswin Sankaranarayanan (Postdoc 2009-2012, Assistant Professor at CMU) has received an NSF CAREER Award for his project "Plenoptic Signal Processing — A Framework for Sampling, Detection, and Estimation using Plenoptic Functions." He will be exploring how light interacts with objects in a scene by studying characterizations of light that go beyond images. A key objective is to study light-object interactions at unprecedented space and time resolutions, thereby advancing research in many disciplines including computer vision, graphics as well as 3D acquisition and printing. Congratulations!

DSP group alums Mark Davenport (PhD 2010, Assistant Professor at Georgia Tech) and Tom Goldstein (Postdoc 2012-14, Assistant Professor at the University of Maryland) have been named 2017 Sloan Research Fellows. The 2017 class of fellows comprises 126 early-career scholars representing the most promising scientific researchers working today (not all have beards). Their achievements and potential place them among the next generation of scientific leaders in the U.S. and Canada. Since 1955, Sloan Research Fellows have gone on to win 43 Nobel Prizes, 16 Fields Medals, 69 National Medals of Science, 16 John Bates Clark Medals, and numerous other distinguished awards. Congratulations!

How thin can a camera be?  Very, say Rice University researchers who have developed patented prototypes of their technological breakthrough.

FlatCam, invented by the labs of Rice DSP faculty members Richard Baraniuk and Ashok Veeraraghavan, is little more than a thin sensor chip with a mask that replaces the lenses in a traditional camera.

Making it practical are the sophisticated computer algorithms that process what the sensor detects and converts the sensor measurements into images and videos.

John Treichler, Rice DSP alum, distinguished visiting professor, and pioneer in the development of digital signal processing (DSP), has been elected to the National Academy of Engineering (NAE).

Now the president of Raytheon Applied Signal Technology of Sunnyvale, Calif., Treichler was cited by the NAE for his “contributions to digital signal processing and its applications to national intelligence gathering.” John is celebrated for inventing the “constant modulus” adaptive filtering algorithm, which is used to compensate for interference, such as multipath echoes, on communication signals.
