I am currently finishing a book, entitled 'Aristotle's Characters'. The book is a study of the four paradigmatic human characters (virtuous, self-controlled, uncontrolled, and vicious) distinguished by Aristotle.

I am also working on several articles:

• Voluntariness in the Eudemian Ethics and the Magna Moralia
  
• The role of the male and the female in Aristotle's Generation of Animals
  
• The discussion between Socrates and Protagoras in Plato's Protagoras
  
• Human nature and the 'ineffable one' in Plotinus
• A chapter on Moral Psychology for the new Cambridge Companion to Aristotle
