Biographical sketch

David Yeh received his B.S. in Electrical Engineering and Computer Science at the University of California at Berkeley. He subsequently received the M.S. in Electrical Engineering at Stanford University. David is currently a Ph.D. candidate in the Audio Signal Processing group at the Center for Computer Research in Music and Acoustics (CCRMA). His research is supervised by Prof. Julius O. Smith, Dr. Jonathan Abel (Consulting Professor), and Prof. Boris Murmann.

Previously David has done summer internships in diverse subject areas. In 2000 he was at the IBM Almaden Research Lab researching algorithms to index resumes on the web. In 2002 he worked at HP Labs to automate a test and measurement setup for thin film diode arrays and characterize their electrical properties. In 2003 and 2006 he worked at National Semiconductor in the Portable Power, and Audio groups respectively, studying the problems of inductor saturation detection, and Class H audio amplifier designs.

From 2003 to 2006 David worked in the Khuri-Yakub Ultrasonics Group in the E.L. Ginzton Laboratory at Stanford. His research interests involved integrated front-end circuit design for ultrasonic transducers, CMUT post-processing MEMS-style, and ultrasonic medical imaging using CMUT transducers. He worked with high-frequency linear arrays of CMUTs for high-resolution imaging, and ring arrays for 3-D imaging in intravascular applications (see publications).

David is interested in applying his prior experiences in circuits and acoustic transducers to research in guitar circuits and DSP algorithms. Currently he is conducting thesis research in the subject of circuits for guitar effects, amp modeling, and loudspeaker acoustics.


David has been supported by the Stanford Graduate Fellowship, the National Defense Science and Engineering Graduate Fellowship, and the National Science Foundation (NSF) Graduate Fellowship.

Thanks to the following individuals for technical or financial support. Bill Broach and Portable Power at NSC. Pierre Khuri-Yakub's lab for an initial research opportunity. Andrei Vladimirescu. Stefan Bilbao.

David thanks his Yamaha S80 keyboard for introducing him to the concept of different kinds of electric guitar distortion.

Above all, he thanks the Lord Jesus Christ for His infinite love for people and God's infinite forgiveness though he is so undeserving. David acknowledges that God has laid down every step in his life so that he could so deeply enjoy his work. Who knew you could get a PhD in guitar distortion? As Bach used to write, "Soli Deo Gloria."
