Diyouva Christa Novith
Professional Profile

Research on how data systems and institutional practice shape the governance of trade.

I study how machine learning, administrative data, and analytic infrastructures reshape decision-making in public institutions, especially in customs and international trade. My work sits at the intersection of technical systems, institutional authority, and policy implementation.

Across customs operations, fiscal analytics, and regional digital trade integration, I am interested in how evidence becomes trustworthy, accountable, and usable once it enters real organizational workflows.
