Research Scientist


Andrew G. West is a Research Scientist on the Verisign Labs team.

He obtained his PhD from the University of Pennsylvania in 2013, writing his dissertation on the topic of security for "open collaboration" applications. His work examined how user-generated content and collaborative semantics are changing how spam and other abuses manifest and can be detected. In addition to yielding over two dozen academic writings his graduate work produced tools still in popular use by communities of practice. Most notably, his anti-damage software STiki has been used to remove nearly 400,000 damaging revisions from English Wikipedia. Popular media outlets such as the Chronicle of Higher Education and Gizmodo have also recognized his contributions.

Transitioning to Verisign, Dr. West plans to leverage the company's wealth of Internet-scale routing and security data using his experience with trust/reputation management, applied machine learning, and metadata analysis methodologies. He is broadly interested in Web 2.0 and network security with more narrow specializations in email/web spam, underground economies, behavioral profiling, Internet virality, and research ethics.

In addition to independent research efforts Dr. West is interested in pursuing mutually-beneficial cooperation through Verisign's University collaboration and intern programs. Having advised over 100 student research endeavours at UPenn he has considerable experience in planning towards successful project outcomes. Finally, he remains in active service to the academic/professional community as a reviewer for multiple conferences and journals.
