Research areas:  International Relations, Philosophy, Social Theory

Having obtained a PhD from the University of Aberystwyth, I joined the Department of War Studies at King's as an Assistant Professor in 2007. Currently I am a senior visiting fellow, working on projects that explore the problem of anarchy, as well as the connection between practice theory and the normative structure of the international realm. Although formally educated in political theory and international relations, my research engages broader questions in philosophy and social theory.

These include:

(1) International relations theory

         -   International political theory

         -    Ethics of war

(2)  Social theory and philosophy of social science

         -  Social practices as normative domains, rule-following (Winch and Wittgenstein)

         -  Early Frankfurt school (Adorno)

         -  Methodology of social science

(3)  Political philosophy

        -  Hobbes, Kant, Oakeshott

        -  Questions of authority, anarchy, and freedom

        -  Social contract theory, 'states of nature'

(4)   Ethics of technology and bioethics


Research Projects

A current project includes Hobbes's conception of a state of nature ('anarchy'), as an unregulated realm of free interaction. The core problem it entails is the uncertainty of transactions and incommensurability of values. A stable solution cannot be a third-party coercion, but only a common set of rules. I explore this puzzle in Hobbesian Internationalism (Palgrave 2019), from the vantage point of political theory as well as in the context of an international anarchy between states.

My book Practice Theory and International Relations (with Mervyn Frost, Cambridge 2018) outlines a theory of social practices. It attempts to clear some conceptual ground by defining the core aspects of practices as normative domains such as constitutive rules, rule-following, and understanding rule-governed action from 'the inside' (Verstehen). It identifies a number of misconceptions. One notable misconception is that a practice (a normative domain constituted by rules) is the same as action (doing). Another one is that a categorical gulf separates praxis from theoria.  What is shown, instead, is that actions are only intelligible under a description and hence are 'theoretical' by default. And, as Wittgenstein and Oakeshott have noted, in rule-following, understanding a rule (the theoretical part) and using it (the practical part) are intertwined. On the plane of IR theory, the book makes the case that the civil state, as well as the society of states, constitute macro-level practices ('closed', ethically fundamental, second-order normative domains) that cannot be reduced to everyday micro practices.

Parallel to this, I have a long-standing interest in contemporary social theory, and in the first-generation Frankfurt school whose disenchantment with late modernity was most powerfully articulated by Adorno. Adorno's critique was directed against contemporary society marked by false positivity and consumerism, understood as the opposite of production in the fundamental sense in which a human being is a producer or maker of one's own world, a free being. The resultant idea of unfreedom as a loss of individuality represents an important kontrapunkt to more recent criticisms of late modernity that draw on ideals of democracy, rights, and equality.

In addition, I have written on moral bioenhancement where my position is that while medical enhancement is an unobjectionable (and perhaps valuable) technique, using it as a tool for moral perfection, leads to dangerous social engineering. A new problematic that I have started working on is the ethics of technology, related to the use of big data and algorithms to predict the behaviour of individuals. The problem here is not well captured by theories of surveillance or autonomy/consent. Rather, it concerns the question of legitimate political authority, and invites us to consider the relation between capital, the state, and the pubic sphere under the conditions of advanced technological capitalism.
