Researcher

Peter Eckersley

Peter Eckersley was a computer scientist whose career connected internet security work with AI ethics and safety research. At EFF, he worked on privacy tools such as Panopticlick, HTTPS Everywhere, Certbot, Privacy Badger, and the SSL Observatory, and he co-founded Let’s Encrypt. He completed a PhD in computer science and law, co-authored a report on malicious AI use, led the Partnership on AI’s research, and worked on SafeLife and AI value alignment. He co-founded the AI Objectives Institute before his death in 2022, and the Internet Hall of Fame named him a posthumous 2023 inductee.

Timeline

  1. 2006

    A Melbourne degree and EFF start

    After graduating from the University of Melbourne, where he majors in mathematics, physics, and computer science, he joins EFF as a staff technologist in 2006. He later becomes EFF’s Chief Computer Scientist and works on privacy and security projects including Panopticlick, HTTPS Everywhere, Certbot, Privacy Badger, and the SSL Observatory.

  2. 2012–2015

    A PhD and Let’s Encrypt

    He completes a PhD in computer science and law at the University of Melbourne in 2012. At the RSA Conference in 2012, he and Alex Halderman plan an automated system for HTTPS certificates. He co-founds Let’s Encrypt, which begins service in 2015.

  3. 2017–2019

    AI value alignment and malicious use

    He presents Impossibility and Uncertainty Theorems in AI Value Alignment as a NIPS poster in 2017. In 2018, he coauthors The Malicious Use of Artificial Intelligence: Forecasting, Prevention, and Mitigation, a report that surveys AI security threats and proposes ways to forecast, prevent, and mitigate them. At SafeAI in 2019, he presents the value-alignment paper, which proposes conjectures about the relationship between uncertainty in objectives and severe unintended consequences.

  4. 2018–2020

    Director of Research at PAI

    In September 2018, he leaves EFF to become the Partnership on AI’s inaugural Director of Research, a role he holds until 2020. He leads research on AI ethics, safety, fairness, inclusiveness, trust, and robustness.

  5. 2019

    SafeLife for reinforcement learning

    With Carroll Wainwright, he releases SafeLife in 2019, a reinforcement-learning environment that tests how agents avoid unwanted side effects while completing tasks.

  6. 2021

    Co-founding AI Objectives Institute

    In 2021, he co-founds the AI Objectives Institute, a non-profit research lab. The institute works to ensure that AI and future economic systems are built and deployed with human objectives at their core.

  7. 2022

    Death after cancer treatment

    He dies in September 2022 from complications of cancer treatment.

  8. 2023

    Internet Hall of Fame induction

    The Internet Hall of Fame names him a posthumous 2023 inductee for helping expand HTTPS adoption.
