Introduction

Edward William “Ed” Felten (born March 25, 1963) is a prominent American computer scientist and technology policy expert. Over decades, he has bridged deep technical work in cybersecurity and system architecture with public service roles and policy advocacy. As a professor at Princeton University, a former Deputy U.S. Chief Technology Officer, and FTC Chief Technologist, Felten’s career illustrates how rigorous science and public responsibility can intertwine.

Early Life and Family

Felten grew up in Madison, Wisconsin. His family acquired one of the early personal computers—a rarity at the time—and young Felten devoted much of his time exploring how it worked, tinkering and learning to program. This environment fostered his curiosity and his eventual path into computing and security.

Education and Academic Formation

• Undergraduate: Felten attended the California Institute of Technology (Caltech), where he graduated in 1985 with a B.S. in physics (with honors).

• Early Research / Work: After graduating, he stayed at Caltech until 1989 as a staff programmer working on parallel computing projects (notably the Current Computing Project), publishing work on high-performance parallel programming.

• Graduate School: Felten pursued graduate studies in computer science at the University of Washington, earning an M.S. in 1991 and a Ph.D. in 1993. His doctoral thesis, “Protocol Compilation: High-Performance Communication for Parallel Programs,” was co-advised by Ed Lazowska and John Zahorjan.

This combination of physics, systems, and parallel computing laid the groundwork for his later pivot into security and policy.

Academic & Research Career

Joining Princeton

After completing his Ph.D., Felten joined Princeton University as an assistant professor in computer science in 1993. He was promoted to associate professor in 1999 and full professor by 2003.
Later, he became jointly appointed to Princeton’s School of Public and International Affairs (SPIA), reflecting his interest in linking technology and policy.

He also founded Princeton’s Center for Information Technology Policy (CITP) and served as its director for many years (aside from his stints in government). Under his leadership, CITP became an important hub for research at the intersection of computing, law, and public policy.

On July 1, 2021, Felten transferred to emeritus status at Princeton after nearly 28 years as a faculty member. Even in emeritus status, he retains involvement in technology policy and entrepreneurship (for example, as cofounder and chief scientist of Offchain Labs).

Areas of Research & Key Contributions

Felten’s scholarly work spans several overlapping domains:

• Computer security & systems vulnerabilities: From early work in Java security (e.g. “Java Security: From HotJava to Netscape and Beyond,” coauthored with Dean & Wallach)

• “Responsible disclosure” and security policy: Felten was a pioneer in responsibly disclosing vulnerabilities—i.e. notifying vendors before public release—and navigating the legal risks that researchers often face.

• Security analyses of real-world systems:
  • Sony / DRM / rootkit — In 2005, Felten and J. Alex Halderman showed that Sony’s CD copy-protection uninstaller introduced a rootkit vulnerability, enabling arbitrary code execution by any visited web page.
  • Voting machine security — In 2006, he (with students) exposed severe flaws in Diebold’s AccuVote-TS electronic voting machines, showing how malicious software could alter votes undetectably.
  • Sequoia voting machines & disclosure conflicts — Study of Sequoia’s systems prompted legal pushback over licensing and analysis.
  • Cold boot attacks — Felten’s group contributed to analysis showing that physical access to memory modules (e.g. via freezing memory chips) could extract encryption keys.

His work often highlights the tension between exposing vulnerabilities (for public benefit) and navigating legal and institutional constraints—the balance of attack, defense, and policy.

Public Service & Government Roles

Felten has interleaved significant public appointments with his academic work:

• Chief Technologist, U.S. Federal Trade Commission (FTC) — From 2011 to 2012, he served as the first-ever Chief Technologist at the FTC.

• Deputy U.S. Chief Technology Officer (in the Obama White House) — From 2015 to 2017, he operated within the Office of Science and Technology Policy (OSTP).

• Privacy and Civil Liberties Oversight Board (PCLOB) — Beginning in 2018, he served as a board member through January 29, 2025.

• Advisory, consulting, expert testimony — Throughout his career, Felten has acted as a consultant or expert for agencies such as Commerce, Defense, Homeland Security, and Justice.

• Expert witness in landmark litigation — Notably, during United States v. Microsoft, he testified for the U.S. government demonstrating that Internet Explorer components could be removed without breaking Windows’s operation.

These roles allowed him to influence policy and regulatory frameworks informed by deep technical understanding.

Historical Context & Significance

Felten’s career sits at a pivotal era in computing: the rise of digital systems, the Internet, software ecosystems, and an accelerating interaction between technology, law, and civil liberties. Key contextual threads include:
