Welcome to the Digital Signal Processing (DSP) group at Rice University. The DSP group has been actively teaching courses, conducting research, and publishing results since 1968.

John Treichler with Sidney Burrus

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.


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.

Digital Signal Processing (http://dsp.rice.edu) is looking for one or more post-doctoral researchers with expertise in computational imaging, signal processing, optics, computer vision and/or machine learning. The candidates must have a PhD in signal processing, optics, computational imaging, computer vision, or machine learning. The candidates will work with Prof. Richard Baraniuk and Prof. Ashok Veeraraghavan on projects that are at the intersection of signal processing, and computational imaging. The candidates will become project leads on one or more projects, and work closely with graduate and undergraduate students. In addition, they will participate in fundraising, preparing them for their future career in a leadership role either in academia or in the industry. Interested candidates should send an email to vashok@rice.edu with the subject "Post-doc position in DSP Group".

DSP alum Chinmay Hedge (PhD, 2012) has won the Best Paper Award at the 2015 International Conference on Machine Learning (ICML) for the paper "A Nearly-Linear Time Framework for Graph-Structured Sparsity" written with his collaborators Piotr Indyk and Ludwig Schmidt from MIT.

This is great momentum for starting in as an Assistant Professor at Iowa State University. Congratulations, Chin!

The first Signal Processing at Rice (SPAR) interactive conference took place March 27th, 2015, in Duncan Hall on the Rice campus. The day of workshops and panels brought a wide variety of DSP group alumni and current group members together to exchange ideas and discuss new directions for collaborative research. The conference opened with unique Lightning Round talks from all participants and also included interactive panels and discussions. The full schedule is available here.
