Senior Technical Advisors

Richard Clayton, Ph.D., Security Researcher, University of Cambridge



Richard Clayton led the team that developed Turnpike, one of the earliest integrated Internet access packages for Windows, giving access to email and Usenet over dialup links. In 1995 his software house was sold to Demon Internet, then the United Kingdom's largest ISP. He worked for Demon in various troubleshooting and regulatory roles until 2000, when he returned to the University of Cambridge to study for a PhD. His thesis was completed in 2005, and he has stayed on as an academic "because it is more fun than working."

Dr. Clayton edited many of LINX's BCP (Best Current Practices) documents, which include some of the earliest formal statements of the terms and conditions that internet service providers must impose to ensure they can deal with abuse of email systems.  In 2007 he became the second recipient of LINX's "Conspicuous Contribution" award.

He currently runs the Cambridge Cybercrime Centre, a five-year initiative to collate datasets about cybercrime and make them available to other academics. The aim is to drive a step change in the number of academic papers that use real world data as the basis for their insights into cybercrime topics.

Jesse Sowell, Ph.D.


Jesse is currently a Postdoctoral Cybersecurity Fellow at Stanford’s Center for International Security and Cooperation. Broadly, Dr. Sowell’s research focuses on the non-state institutions that ensures the internet stays glued together in a secure and stable manner.

This work started with studies of how operational communities share information necessary to solve operational and security incidents that often cross firm and jurisdictional boundaries. Historically, these actors have served as the stewards of the internet’s infrastructure. Increasingly, the social, political, and economic magnitude of cybersecurity incidents requires the capabilities of both operational communities and state actors. Dr. Sowell’s ongoing work explores the operational-policy interface between operational security communities and state actors, in particular law enforcement and national security.

Dr. Sowell’s other research interests include the role of private transnational security regimes in global politics, the commodification of malware value networks, credible knowledge assessment of science and technology policy, the economics of IoT security, and the growing tension between internet privacy and security efforts. At M3AAWG, Dr. Sowell serves as a Senior Advisor and vice-chair of the Growth and Development Committee, directing the organization’ outreach efforts. He also serves as the co-chair of the IoT Special Interest Group.

Dr. Sowell has a background in computer science, criminal justice, and technology and policy. He holds a PhD in Technology, Management, and Policy from MIT’s Engineering Systems Division
