He has contributed significantly to the development and validation of assessment tools like the Personality Assessment Screener (PAS) and the DSM-5 Alternative Model for Personality Disorders.

He has authored over 150 peer-reviewed articles and book chapters, many focusing on personality functioning, validity indicators, and longitudinal stability of traits.
