Ronald Schafer, recognized as one of the world's leading authorities on digital signal processing, has joined HP Labs as the newest HP Fellow.

Schafer, who co-authored the digital signal processing field's definitive guide and did some of the earliest research in the field, will work in the Mobile and Media Systems Lab on problems of acoustic signal processing for audio communication and entertainment.

Schafer joins HP from the Georgia Institute of Technology, where he and his colleagues built the world's most prestigious signal processing laboratory in academia, the Center for Signal and Image Processing.

Digital Signal Processing (DSP) is the technology of representing signals such as speech, audio, and video in digital form and the modification, transmission, and storage of such digital signals using digital computation and communication. DSP underlies a wide range of modern electronic systems, from mobile phones to modems to digital cameras and multimedia PCs.

His research in topics such as cepstrum analysis, digital interpolation and time-frequency analysis/synthesis has been applied to in today’s digital speech processing systems for data compression for mobile phones and voice-over IP and for voice I/O for computers. His contributions in areas such as iterative algorithms, mathematical morphology, 3D reconstruction, statistical modeling and interpolation have had important impact in areas such as medical imaging, neurobiology, wireless communication systems and digital photography.

In addition to his work in academia, Schafer founded Atlanta Signal Processors Inc., which created the first design tools for software development for Texas Instruments' first programmable digital signal processor.

"Ron brings to HP a unique mix of technical and business savvy," said Dick Lampman, senior vice president for research, HP and director of HP Labs.

Schafer has been a close collaborator with Hewlett-Packard Laboratories for many years. He is co-inventor of one patent and co-author of numerous research papers with HP Labs researchers, and he was instrumental in initiating many other research collaborations between Georgia Tech faculty and HP Labs researchers.

"The collaborations that Ron forged with HP and other companies have provided a model for successful university/industry interaction," Lampman said.

The title of HP Fellow is reserved for the company's most talented technical leaders; employees whose innovative spirits have inspired the technology community.

HP Fellows demonstrate major impact across multiple technical and business areas, applying exceptional depth and breadth of knowledge to important, complex problems. Recognized as technical authorities, Fellows identify emerging technical trends and help focus HP resources to tap their potential.
