About Sean W. Smith

Sean SmithProfessor Sean Smith has been working in information security - attacks and defenses, for industry and government - since before there was a Web. As a post-doc and staff member at Los Alamos National Laboratory, he performed security reviews, designs, analyses, and briefings for a wide variety of public-sector clients; at IBM T.J. Watson Research Center, he designed the security architecture for (and helped code and test) the IBM 4758 secure coprocessor, and then led the formal modeling and verification work that earned it the world's first FIPS 140-1 Level 4 security validation. In July 2000, Sean left IBM for Dartmouth, since he was convinced that the academic education and research environment is a better venue for changing the world. His current work, as PI of the Dartmouth PKI/Trust Lab, investigates how to build trustworthy systems in the real world. Sean was educated at Princeton (A.B., Math) and CMU (M.S., Ph.D., Computer Science), and is a member of Phi Beta Kappa and Sigma Xi.

About John Marchesini

John MarchesiniDr. John Marchesini received a B.S. in Computer Science from the University of Houston in 1999 and, after spending some time developing security software for BindView, headed to Dartmouth to pursue a Ph.D. There, he worked under Professor Sean Smith in the PKI/Trust lab designing, building, and breaking systems. John received his Ph.D. in Computer Science from Dartmouth in 2005 and returned to BindView, this time working in BindView's RAZOR security research group. He conducted numerous application penetration tests and worked closely with architects and developers to design and build secure systems. In 2006, BindView was acquired by Symantec and he became a member of Symantec's Product Security Group, where his role remained largely unchanged. John recently left Symantec and is now the Principal Security Architect at EminentWare LLC.
