Michael E. O'Sullivan

Michael E. O'Sullivan is a Professor and Chair in the Department of Mathematics and Statistics at San Diego State University. He has taught advanced courses such as Commutative Algebra and Algebraic Geometry (Math 621) and Groups, Rings, and Fields (Math 620), with a focus on integrating computational tools like Sage, Maple, and Magma into his teaching.

• Research Focus: His work centers on Coding Theory, particularly Algebraic Geometry Codes, Hermitian Codes, and LDPC Codes. His research includes developing decoding algorithms (e.g., Groebner basis methods, Sudan's list decoding), analyzing code properties (e.g., minimum distance, redundancy), and optimizing code constructions.
• Publications: His most recent articles (2014–2006) address unique decoding of AG codes, list decoding techniques, and applications of algebraic structures to code optimization. These span journals like IEEE Transactions on Information Theory and Designs, Codes and Cryptography, as well as conferences such as IEEE International Symposium on Information Theory and Canadian Workshop on Information Theory.
