Dr. Andreas G. Andreou is a professor in the Electrical and Computer Engineering Department of the Whiting School of Engineering at the Johns Hopkins University. His research program examines the relationship between information, and its physical representation in both biological and in engineered information processing systems. His group studies new ways of transforming and communicating information that exploit physical properties of the underlying technologies; from integrated circuit design principles that rely on the non-linear characteristics of CMOS devices, to high speed serial wireless communication between chips and silicon on sapphire CMOS circuits, to micromechanical structures for acoustic processing and 3D CMOS technology. They also explore unique and innovative methods to acquire data and extract information making use of a-prioriknown physical properties of the problem; from engineering single chip integrated polarization imagers to compensating for speaker variability and statistical signal processing in speech recognition through vocal tract normalization. At a more fundamental level, they employ elements of communication and information theory, to analyze, establish quantitative and relevant measures for performance and engineer closed loop sensor/motor systems, at different scales, macro to micro and nano.
