Short Biography

Professor Bocko earned his PhD in Physics from the University of Rochester in 1984 with research in the field of gravitational wave detectors and the quantum limits of weak force detection in the group of David H. Douglass. After a brief post-doctoral appointment in the same laboratory, he joined the Rochester ECE department in 1985. His research has spanned multiple areas with its current focus on audio and acoustic signal processing.  Previous research has been in the areas of electromechanical transducers, image sensors, non-contact ECG sensors, low-noise electronics, digital superconducting electronics, quantum coherent electronics, quantum computing, and quantum noise. He is also the Director of the Center for Emerging and Innovative Sciences (CEIS), a NYSTAR supported Center for Advanced Technology at the University of Rochester with the mission of promoting economic development through joint university-industry research and technology development. Professor Bocko has taught courses on solid state devices, microwaves, circuits and systems, audio signal processing, and acoustics. He was won five teaching awards at the University of Rochester and was named the Mercer Brugler Distinguished Teaching Professor at the University from 2008-2011. He was named Distinguished Professor of Electrical and Computer Engineering in 2013 and served as Chair of the ECE Department from 2004-2010 and again from 2012 to the present time.

Research Overview

Audio and Acoustic Signal Processing

Professor Bocko's current research focus is in the field of audio and acoustic signal processing. Active research projects include the development of flat panel loudspeakers and spatial audio displays, spatial audio characterization and rendering, efficient modeling of room impulse responses and other acoustic systems, characterization of musical vibrato, and musical expression and computer based musical performance style analysis. Previous research projects include audio source separation and computer music transcription, development of empirically based physical models for musical sound synthesis, compact model-based musical sound representations and audio watermarking and steganography.

Sensors

Professor Bocko's earlier research on sensors and transducers began with his PhD thesis on the quantum limits of gravitational wave detectors and back action evasion measurements. Other work in this area includes the development of highly sensitive capacitive displacement sensors and quantum limited electron tunneling displacement sensors. More recent work has been in the areas CMOS image sensors, non-contact electrocardiogram sensors, and micro-power smart sensors for machine health monitoring.

Superconductivity

Previous research projects have employed superconductivity for several applications, including high-frequency digital signal processing circuits and analog circuits for the detection of weak electromagnetic and mechanical signals. In 1996, Professor Bocko's group was the first to propose a realistic design for a quantum computer using superconducting Josephson junction circuits; and subsequently studied quantum coherence in Josephson junction circuits and the use of RSFQ superconducting qubit control electronics and nondestructive readout techniques for superconducting and electromechanical qubits.
