• Relevant hands-on experience leading IND/CTA and/or NDA/MAA submissions. 
• Proven success in: 
• Leading Pre-IND or INTERACT meetings and IND/CTA submissions for psychiatry/neurology programs. 
• Designing Phase II PoC studies with validated endpoints. 
• Preparing Phase III-ready protocols and health authority interactions (FDA EOP2, scientific advice, Pre-NDA). 
• Deep knowledge of global regulatory frameworks and eCTD submission standards. 
• Practical, applied fluency in FDA/EMA neuroscience guidelines and ICH standards. 
• Proficiency with publishing and document management tools (e.g., Veeva, Smartsheet, Office Timeline Pro)
