Information and Applications

Our group’s research lies between the information sciences and emerging applications in data storage and communications. Our aim is to develop new frameworks with practical benefits to real-world information-systems. The engines of the new frameworks are constructive contributions in coding theory, information theory and algorithms. The new constructs are evaluated using both analytic and experimental treatments.

To span the broad research from theory to implementation, our group welcomes contributors (graduate students, post-docs) and collaborators with a broad set of research interests and inclinations: from deep theoreticians to system wizards.
