Some recent papers of mine
Representational Analyticity (2005)
in Mind and Language
The traditional understanding of analyticity in terms of concept containment is revisited, but with a concept explicitly understood as a certain kind of mental representation and containment being read correspondingly literally. The account provided here illustrates some interesting features of representations and explains, at least in part, the special epistemic status of analytic judgments.

Lesion Studies, Spared Performance, and Cognitive Systems (2003) in Cortex

A short discussion piece in a behavioral neuroscience journal on the logic of double dissociation research in cognitive neuroscience.

Perceptual Belief and Nonexperiential Looks (2005) in Philosophical Perspectives

I argue that there is a sense of perceptual appearance verbs (like 'looks', as in 'the table looks brown from here') that does not purport to characterize the agent's experiential state. This sense is connected instead to the cognitive scientific conception of perceptual systems. This nonexperiential sense of looks allows us to solve certain longstanding problems in epistemology, particularly that concerning the distinction between perception and inference.

In Defense of Epiphenomenalism
(2006) in Philosophical Psychology

A version of functionalism really does imply that mental properties are causally irrelevant, but this is a virtue of the theory, rather than a vice.

Clades, Capgras, and Perceptual Kinds
(2007) in Philosophical Topics

I develop a notion of perceptual kinds---similarity clusters of distal stimuli---to try to provide a (partial) principled answer to questions about the contents of perceptual states. The resulting view allows for fairly high level contents in perception (e.g., cat, table, etc.,) and not just low level properties of objects (e.g., shiny, presenting-elliptically-from-this-angle, etc.), while avoiding what I take to be certain liberal excesses (e.g., causal relations, semantic properties, etc.)
Experience, Evidence, and Externalism
--forthcoming--
The famous Sellarsian Dilemma, or something like it, actually provides an argument for a strongly externalist epistemology. (I had originally called this "Externalism and the Sellarsian Dilemma", but this seemed to make readers expect a paper on Sellars. They were disappointed.)
Book

Perception and Basic Beliefs: Zombies, Modules, and the Problem of the External World
--forthcoming on Oxford University Press--

Here is the table of contents from a draft of the manuscript to give a better idea of the book; please contact me if you'd like to see more.

I try to answer two central questions in epistemology: which beliefs are epistemologically basic (i.e., noninferentially justified)? and where does perception end and inferential cognition begin? I offer a highly externalist theory, arguing that it is not introspectible features of the beliefs that determine their basic or perceptual status; instead, this is determined by the nature of the cognitive system, or module, that produced them. On my view, the sensory experiences that typically accompany perceptual beliefs play no indispensible role in the justification of these beliefs. Thus even "zombies" --- who in the philosophical parlance have no conscious experiences --- can have (justified) perceptual beliefs.

I hold that perceptual beliefs are a species of basic beliefs, although there are other basic beliefs, and some beliefs are nonbasic, thus requiring inferential support from other beliefs for their justification. This last point is used to defend a reliabilist epistemology against an important class of traditional objections (where the agent uses a reliable process that she doesn't know to be reliable). The overall view I defend is a type of reliabilism, and I use the basic/nonbasic distinction developed here to offer a version of reliabilism that takes inference seriously yet remains staunchly externalist.
