My main research interests are in computational number theory, cryptography and the design and development of special-purpose hardware devices. My work in computational number theory extends from analyzing the complexity of number theoretical algorithms to actually implementing and testing such algorithms. I am also interested in developing parallel algorithms for solving certain number theoretic algorithms, particularly regulator and class number computation in real quadratic number fields.
