More Experts


Andrew Lohn is an engineer at the RAND Corporation. He applies a wide range of mathematical and machine learning techniques to provide new insights in highly technical policy issues like cyberwarfare, artificial intelligence, or drone delivery. His diverse skill set and flexibility allows for rigorous—often quantitative—methodologies even when the project direction is unclear at the start. Prior to joining RAND, Lohn worked in nanotechnology developing photovoltaics, thermoelectrics, optical systems, and computing devices at NASA, HP Labs, Sandia National Labs and a few small companies he spun out. He has published 50 peer reviewed academic papers and has 4 patents awarded or pending. Lohn holds a Ph.D. in electrical engineering from the University of California, Santa Cruz.

    What Do Meltdown, Spectre, and RyzenFall Mean for the Future of Cybersecurity?

    Unlike most previous cyber threats, a new wave of vulnerabilities attack a computer's hardware, rather than its software. What does this mean for cybersecurity as a whole?

    Will Artificial Intelligence Undermine Nuclear Stability?

    In the coming years, AI-enabled progress in tracking and targeting adversaries' nuclear weapons could undermine the foundations of nuclear stability. Will AI someday be able to guide strategy decisions about escalation or even launching nuclear weapons?

    Should We Fear an AI Arms Race?

    Stephen Hawking, Elon Musk, Steve Wozniak, and others signed a letter calling for a ban on the application of artificial intelligence to advanced weapons systems. AI weapons are not without risks, but the benefits are substantial and the risks can be mitigated with more moderate regulation than a ban.
