As the prevalence of sophisticated and inexpensive data collection technology increases, so does our need for accurate and efficient data transmission, storage, analysis, and interpretation. Critical applications such as medical imaging, astrophysics, bioinformatics, communication networks, data mining, and pattern recognition all hinge on our ability to process very large collections of data. The extraction of useful information from data which may be distorted, error riddled, corrupted, or partially irrelevant, or "information processing", is a fundamental challenge faced by diverse fields, from engineering and homeland security to advertising, search engine development, and environmental monitoring. Both my teaching and research are focused on fundamental methodological and theoretical aspects of information processing with a wide variety of important and exciting applications.
