About

Over 15 years in neuroscience R&D, I have led teams from target identification through preclinical candidate delivery, including programs in neurodevelopmental disorders, epilepsy, sleep, and neurodegenerative diseases. I have built iPSC-based disease modelling platforms from the ground up, introduced single-cell transcriptomics and AI-assisted image analysis pipelines, and managed cross-functional teams including in academic and pharma partnerships. Currently exploring senior research leadership roles in biotech and pharma, and open to consulting in drug discovery strategy, translational disease modelling, and AI-driven R&D portfolio development. Participant in the inaugural cohort of the AI Business Specialist Leadership Program at the Graduate School of Applied Technology & Management, Zurich (towards federal certificate of advanced studies).
