My core concern is the Metaphysics, Epistemology and Methodology of Causality in the Sciences, but I have wide research interests in Philosophy of Science, particularly Philosophy of Biology and Psychology, the still-expanding Mechanisms debate, and the relatively new but vibrant Philosophy of Information. I also enjoy Plato, and can never entirely resist Ethics and Political Philosophy, which I don't have time to research, but love to teach.
I am working on an AHRC network project on Evidence and the Mechanisms Hierarchy, which looks at the problems of causal inference using mechanisms. This is in collaboration with Federica Russo and Jon Williamson at Kent, and with Brendan Clarke and Donald Gillies at UCL STS:

The book aims to introduce causality to an interdisciplinary audience, showing them how the results of the recent explosion in philosophical theorizing about causality can be of use to them.

In the last decades, Systems Biology (including cancer research) has been driven by technology, statistical modelling and bioinformatics. In this paper we try to bring biological and philosophical thinking back. We thus aim at making different traditions of thought compatible: (a) causality in epidemiology and in philosophical theorizing – notably, the “sufficient-component-cause framework” and the “mark transmission” approach; (b) new acquisitions about disease pathogenesis, e.g. the “branched model” in cancer, and the role of biomarkers in this process; (c) the burgeoning of omics research, with a large number of “signals” and of associations that need to be interpreted. In the paper we summarize first the current views on carcinogenesis, and then explore the relevance of current philosophical interpretations of “cancer causes”. We try to offer a unifying framework to incorporate biomarkers and omic data into causal models, referring to a position called “evidential pluralism”. According to this view, causal reasoning is based on both “evidence of difference-making” (e.g. associations) and on “evidence of underlying biological mechanisms”. We conceptualize the way scientists detect and trace signals in terms of information transmission, which is a generalization of the mark transmission theory developed by philosopher Wesley Salmon. Our approach is capable of helping us conceptualize how heterogeneous factors such as micro and macro – biological and psycho-social – are causally linked. This is important not only to understand cancer etiology, but also to design public health policies that target the right causal factors at the macro-level.

Current research in molecular epidemiology uses biomarkers to model the different disease phases from environmental exposure, to early clinical changes, to development of disease. The hope is to get a better understanding of the causal impact of a number of pollutants and chemicals on several diseases, including cancer and allergies. In a recent paper Russo and Williamson (Med Stud, 2012) address the question of what evidential elements enter the conceptualisation and modelling stages of this type of biomarkers research. Recent research in causality has examined Ned Hall’s distinction between two concepts of causality: production and dependence (Hall in Causation and counterfactuals. MIT Press, Cambridge, pp 225–276, 2004). In another recent paper, Illari (Philos Technol, p 20, 2011b) examined the relatively under-explored production approach to causality, arguing that at least one job of an account of causal production is to illuminate our inferential practices concerning causal linking. Illari argued that an informational account solves existing problems with traditional accounts. This paper follows up this previous work by investigating the nature of the causal links established in biomarkers research. We argue that traditional accounts of productive causality are unable to provide a sensible account of the nature of the causal link in biomarkers research, while an informational account is very promising

"Craver claims that mechanistic explanation is ontic, while Bechtel claims that it is epistemic. While this distinction between ontic and epistemic explanation originates with Salmon, the ideas have changed in the modern debate on mechanistic explanation, where the frame of the debate is changing. I will explore what Bechtel and Craver’s claims mean, and argue that good mechanistic explanations must satisfy both ontic and
epistemic normative constraints on what is a good explanation. I will argue for ontic constraints by drawing on Craver’s work in section 2.1, and argue for epistemic constraints by drawing on Bechtel’s work in section 2.2. Along the way, I will argue that Bechtel and Craver actually agree with this claim. I argue that we should not take either kind of constraints to be fundamental, in section 3, and close in section 4 by considering what remains at stake in making a distinction between ontic and epistemic constraints on mechanistic explanation. I suggest that we should
not concentrate on either kind of constraint, to the neglect of the other, arguing for the importance of seeing the relationship as one of integration."

Russo and Williamson claim that establishing causal claims requires mechanistic and difference-making evidence. In this paper, I will argue that Russo and Williamson’s formulation of their thesis is multiply ambiguous. I will make three distinctions: mechanistic evidence as type vs object of evidence; what mechanism or mechanisms we want evidence of; and how much evidence of a mechanism we require. I will feed these more precise meanings back into the Russo-Williamson Thesis and argue that it is both true and false: two weaker versions of the thesis are worth supporting, while the stronger versions are not. Further, my distinctions are of wider concern because they allow us to make more precise claims about what kinds of evidence are required in particular cases.

In this paper, I examine the comparatively neglected intuition of production regarding causality. I begin by examining the weaknesses of current production accounts of causality. I then distinguish between giving a good production account of causality, and a good account of production. I argue that an account of production is needed to make sense of vital practices in causal inference. Finally, I offer an information-transmission account of production based on John Collier's work, that solves the primary weaknesses of current production accounts: applicability and absences.

This paper argues against evidential decision-theory, by showing that the newest responses to its biggest current problem – the medical Newcomb problems – don’t work. The latest approach is described, and the arguments of two main proponents of it – Huw Price and CR Hitchcock – examined. It is argued that since neither new defence is successful, causation remains essential to understanding means-end agency.

Much of science aims to find and use causes. Does penicillin cure bacterial infection? How big a dose and how often should we give it for it to be effective? Mechanisms are most obviously important in the biomedical sciences, but are relevant far beyond them. For example, we seek to explain how penicillin cures bacterial infection by describing the mechanism by which it kills bacteria in the body. So finding evidence of causes and mechanisms is a core problem of science. Further, our fundamental view of the world we live in has been profoundly affected by the kinds of causes and mechanisms we discover. This module explores the most important views of causality and mechanisms and how we seek evidence for them, and examines how they affect our view of the world around us.

Information has been of vital interest to science for at least half a century, gradually spreading so that it is now of interest right through from physics to psychology. Within the last decade information began touching the lives of ordinary people, and exploded to increasingly dominating those lives - particularly the lives of the young. We use email and webpages regularly, google is the first port of call for any problem, and Skype is essential to keep in contact with friends across the globe. We create a personal identity online with personal webpages, Facebook, Twitter, blogs, youtube, flickr. The smart phone population is increasing, and many people will part from their families, friends, lovers and children faster than they part from their smart phone. This world is growing so quickly that the concepts we need to think about it cannot keep up. Ethics and culture are dragging behind. We don't know how to make laws for and police the global online world. This has advantages in terms of freedom; but it has disadvantages in terms of unrecognised dangers, such as identity theft. There is also an increasingly serious division between those at home in this new world, and so with access to all its resources; and those who are shut out. In this course we explore the new philosophy of information, an approach aimed at making sense of this apparently new world. We will look at concepts of information, aspects of our use of information, our epistemic access to it, and the ethics of information.

This course explores topics in the philosophy of the natural sciences. In the philosophy of physics, we will address how quantum mechanics has changed our view of physical reality; and how particle physics has had an impact on philosophical debates about realism and antirealism in science, such as recent literature on structural realism. We will interrogate the philosophical literature on mechanisms and causality by considering astrophysical mechanisms. In the philosophy of chemistry, we will assess the periodic table as a system of classification and particular philosophical problems presented by molecular structure and shape and biomolecular visualisation. We will also discuss problems common to both physics and chemistry such as problems of data, simulation and modelling.

This is an examination of naturalistic philosophical methodology, focusing on the causality literature. I will briefly introduce the use of examples and cases in the literature (section 2). I then turn to methodology, surveying naturalistic concerns about philosophy (section 3.1), and work on the methodology of philosophy of science (section 3). I will then show why there are legitimate concerns about the use of both toy examples and scientific cases (section 4). I move on (section 5) to examine the four influential papers I have chosen, to show how good work can still be done. I discuss what can be achieved using simplified examples (section 6), before
finishing with examining in depth what scientific cases can do (section 7).
