Brief Biography


I am a tenacious and curious German-Brazilian man committed to advancing the quality of life for individuals affected by mood and other mental disorders through research and patient- centred care. With residency training in both Internal Medicine and Psychiatry, and a dual PhD in Psychiatry and Neurosciences completed through international collaborations with INSERM (France) and Brazil’s Postgraduate Psychiatry Program, followed by postdoctoral fellowships at INSERM, the Pasteur Institute, and CNRS in Paris, I bring a comprehensive and globally informed medical and research perspective across diverse clinical and academic settings.
