Andreas Andreou, a professor of electrical and computer engineering, is the co-founder of the Johns Hopkins University Center for Language and Speech Processing. Research in the Andreou lab is aimed at brain-inspired microsystems for sensory information and human language processing. Notable microsystems achievements over the last 25 years include a contrast sensitive silicon retina, the first CMOS polarization-sensitive imager, silicon rods in standard foundry CMOS for single-photon detection, and a large scale mixed analog/digital associative processor for character recognition. Significant algorithmic research contributions in pattern analysis and machine intelligence include the vocal tract normalization technique for speech recognition and heteroscedastic linear discriminant analysis, a derivation and generalization of Fisher discriminants in the maximum likelihood framework.
An IEEE Fellow, Andreou has secondary appointments in the Department of Computer Science and the Whitaker Biomedical Engineering Institute.
