I received a PhD in Philosophy from the University of Sheffield (UK) in 2007, a PostGrad Diploma in Philosophy from the University of Sheffield in 2002, and a BA in Philosophy from the University of Murcia (Spain) in 2000. My PhD supervisors were Stephen Laurence, Rosanna Keefe, and Dominic Gregory.  My PhD thesis was on "Consciousness, Conceivability and Concepts". 

I joined the University of Manitoba as an Assistant Professor of Philosophy in July 2008, and I was promoted to Associate Professor in March 2014. I was a Visitor at Logos - Research Group in Analytic Philosophy (University of Barcelona, Spain) during March-June 2008 and January-June 2012, and I became a Member in January 2014. I joined the University of Barcelona as a RyC Researcher in July 2014.

The questions that first brought me to philosophy were mainly these: "What is the place of the mind in a natural world?" and "How do mind and language represent the world?". I am still pretty much interested in these, and other related issues. I have also developed an interest in issues having to do with gender, race and sexuality, and more in particular with the ways in which we think about those human kinds, and the ways in which our thinking about them helps to create and perpetuate them.

My research so far has focused on the following questions:

  1. What is the nature of consciousness? Is consciousness physical? Is physicalism true?
  2. What is the best theory of phenomenal concepts? Can we use this theory of phenomenal concepts in order to block anti-physicalist arguments?
  3. What is the role of conceptual analysis in philosophy, and especially in metaphysics?
  4. Is two-dimensional semantics any good?
  5. What is the meaning of ‘woman’? Can we make sense of the sex-gender distinction?
  6. What does it mean to say that a category is socially constructed? Are gender, race and sexual orientation socially constructed?

In my future research, I would also like to address the following questions:

  1. What is the difference between descriptive and ameliorative projects in philosophy?
  2. What is the semantics of slurs, and other pejorative terms such as slurring uses of generics? How can we explain their offensiveness? What is the nature of the corresponding signified properties?
  3. What are social kinds? How do they differ from natural kinds, and artefactual kinds?
  4. What is the nature of truth in fiction? Do moral and political considerations play a role in determining what is true in a work of fiction?
