Occupational Convergence or Divergence?

I gave an invited talk at the UC Davis Center for Poverty & Inequality Research (Sacramento, CA) on how automation and AI are transforming global labor markets, using large-scale job posting data and network analysis to uncover patterns in AI skill demand across occupations and regions. The project is supported by an interactive platform, The Occupation Observatory.

Emergence and Evolution of Semantic Complexity in Urban Digital Twins

As part of the 20th anniversary of the Network Science Society’s flagship conference, I introduced an NLP-powered AI tool for tracing the evolution of semantic complexity in scientific concepts across publications, with a focus on Urban Digital Twins. The project is complemented by an interactive dashboard, The Conceptual Hub.
