    The question of whether new rules or regulations are required to govern, restrict, or even prohibit the use of autonomous weapon systems has been the subject of debate for the better part of a decade. Despite the claims of advocacy groups, the way ahead remains unclear since the international community has yet to agree on a specific definition of Lethal Autonomous Weapon Systems and the great powers have largely refused to support an effective ban. In this vacuum, the public has been presented w…Read more

    Defending Democracies: Combating Foreign Election Interference in a Digital Age (edited book)
    with Duncan B. Hollis
    Oxford University Press. 2021.
    Election interference is one of the most widely discussed international phenomena of the last five years. Russian covert interference in the 2016 U.S. Presidential Election elevated the topic into a national priority, but that experience was far from an isolated one. Evidence of election interference by foreign states or their proxies has become a regular feature of national elections and is likely to get worse in the near future. Information and communication technologies afford those who would…Read more

    What if Cyberspace Were for Fighting?
    with Duncan B. Hollis
    Ethics and International Affairs 32 (4): 441-456. 2018.
    This essay explores the ethical and legal implications of prioritizing the militarization of cyberspace as part of a roundtable on “Competing Visions for Cyberspace.” Our essay uses an ideal type—a world that accepts warfighting as the prime directive for the construction and use of cyberspace—and examines the ethical and legal consequences that follow for who will have authority to regulate cyberspace; what vehicles they will most likely use to do so; and what the rules of behavior for states a…Read more

    Necessity in International Law
    with Larry May
    Oxford University Press USA. 2016.
    Necessity is a notoriously dangerous and slippery concept-dangerous because it contemplates virtually unrestrained killing in warfare and slippery when used in conflicting ways in different areas of international law. Jens David Ohlin and Larry May untangle these confusing strands and perform a descriptive mapping of the ways that necessity operates in legal and philosophical arguments in jus ad bellum, jus in bello, human rights, and criminal law. Although the term "necessity" is ever-present i…Read more

    Personal Identity Without Persons
    Dissertation, Columbia University. 2002.
    The project takes as its starting point our conflicting intuitions about personal identity exposed by Bernard Williams' thought experiment involving the switching of bodies in "The Self and the Future." The conflicted intuitions are identified as animalist and psychologist and correspond roughly with the two major approaches to personal identity. The traditional strategy to resolve the conflict---thought experiments---is critically examined and the project concludes that proper thought experimen…Read more

    Although vicarious liability for the acts of co-conspirators is firmly entrenched in federal courts, no adequate theory explains how the act and intention of one conspirator can be attributed to another, simply by virtue of their criminal agreement. This Article argues that the most promising avenue for solving the Pinkerton paradox is an appeal to the collective intention of the conspiratorial group to commit the crime. Unfortunately, misplaced skepticism about the notion of a group will has pr…Read more

    The concept of the person is widely assumed to be indispensable for making a rights claim. But a survey of the concept's appearance in legal discourse reveals that the concept is stretched to the breaking point. Personhood stands at the center of debates as diverse as the legal status of embryos and animals to the rights and responsibilities of corporations and nations. This Note argues that personhood is a cluster concept with distinct components: the biological concept of the human being, the …Read more
