About mroch:
Professor Marie A. Roch received her Ph.D. degree from The University of Iowa. Prior to joining San Diego State University, she held positions at Florida International University and AT&T Bell Laboratories. Professor Roch's research interests are in pattern recognition, particularly as applied to the categorization of audio signals. Sample projects include pattern recognition for bioacoustics using passive remote acoustic sensors, classifier control systems for hearing aids, diarization, and high level speaker recognition.

Other areas of interest which are not active research areas for Professor Roch include computer vision and telephony.
