Hailing from Singapore, Xin Lin worked as a military officer in the Republic of Singapore Air Force. Apart from operational tours, she had the opportunity to take part in strategic planning and develop warfighting concepts. Xin Lin read European Social and Political Studies at UCL for her undergraduate degree and specialised in Political Theory and Philosophy. Political Philosophy remains a key field of interest to her.

Xin Lin is interested in the role of emerging technologies in public policy, for example, the implementation of AI-based solutions in the policymaking process might force a trade in procedural and substantive legitimacy for efficacy, and the challenges associated with the proliferation of autonomous systems in the realm of defence.
