I'm a Bachelor in Geography and History, specialized in Early Modern History, and Doctorate in Gender History/ Colonial America. I'm a senior archive technician and an expert in paleography. I have a vast professional experience in historical and genealogical counseling and research, as well as in studies on nobility with Sephardi roots, and paleographic transliteration of manuscripts. Depending on the requirements of the investigation, I work in coordination with a group of specialists in several fields, who are integrated into the Pandora Collective.
