Youna is a bilingual former French litigator with 12+ years of international practice in Asia and Europe. Passionate about the ocean, Youna later studied marine sciences and holds a Masters in Marine Affairs from the University of Washington. She is currently also pursuing a PhD with ANCORS. 

Youna’s dual expertise in law and marine sciences uniquely position her to integrate these fields for marine policy making purposes and has led her to spearhead and coordinate several multidisciplinary research projects at CIL including: the prospects for re-use of obsolete offshore installations as artificial reefs in Southeast Asia, sensitivity mapping for Singapore in the context of oil spill preparedness and response and the mapping of shallow features in the South China Sea. 

She is bilingual French and English, has worked across Europe, the U.S. and Asia and, besides her Masters in Marine Affairs, holds an LLM and two Bachelors from La Sorbonne respectively in international public and private law and in procedural law. 

Research interests:
