My first research interest has been the nature of concepts and categorization. I published on theories of concepts, the rule-following discussion and conceptual normaitivity, and on linguistic relativity (the idea that linguistic differences influence thought).
Now I am focused on the philsophy of psychiatry (more generally of psychopathology), and on some conceptual issues in philosophy of medicine.
More specifically I have published or I am writing on:
-the nature of mental disorders
-adequacy of current nosologies (DSM-5 and others)
- the problem of explanation in psychiatry (mechanistic, pluralistic etc.)
- overdiagnosis and overtesting
-why people d not trust medical experts, with a focus on vaccine hesitancy
-appropriateness in healthcare
