Research Interests

  • 1. Studies on the pathophysiology of schizophrenia during brain development. These include studies in mouse models and in neuronal lines derived from patient's skin via reprogramming, to address the specific influence of genetic variations on the susceptibility of neurons to negative environmental events.
  • 2. Development of a strategy for primary prevention of schizophrenia based on a combination of phenomics (based on a specific pathophysiology) and genomics using machine learning and optimization research.
  • 3. Personalization of patient selection for neuromodulation techniques based on predictive maps derived from unbiased search of the variable space and optimization research.
  • 4. Optimized prediction of outcomes in treatment refractory depression treated with neuromodulation techniqes.
