Johannes Wachs

Johannes Wachs is an Associate Professor (Docens) at the Institute of Data Analytics and Information Science, Corvinus University of Budapest, and a Research Fellow at the Institute of Economics, Centre for Economic and Regional Studies. He maintains an affiliation with the Complexity Science Hub Vienna, focusing on interdisciplinary research at the intersection of data science, network theory, and socioeconomic systems.

His educational background includes a PhD in Network Science (summa cum laude, Central European University, 2019), an MS in Applied Mathematics with distinction (Central European University, 2012), and dual BS degrees in Mathematics and Economics (cum laude, Tulane University, 2009).

Wachs specializes in analyzing social, technical, and economic networks, with recent emphasis on the societal impact of software systems—particularly open-source ecosystems and AI technologies. His work employs computational social science methods to investigate developer behavior, innovation diffusion, and network-driven inequality. Key research threads include software ecosystem dynamics, corruption detection in public procurement, and urban network segregation effects on socioeconomic disparities.

His publication portfolio reveals a strong focus on open-source software geography, AI's societal implications, and network-based corruption analysis, with increasing attention to generative AI's impact on knowledge-sharing platforms and software development workflows since 2023.

Scientific recognition includes:

• IMF Anti-Corruption Challenge (2020)

He actively supervises doctoral candidates including Hannah Schuster (WU Wien/CSH) and Brigi Németh (Corvinus University), alongside mentoring numerous bachelor's theses on topics ranging from corruption analytics to Stack Overflow dynamics. Major funded projects include the Hungarian Research Funding Agency's Building Blocks of the Digital Economy (2024-2027) and the FFG-supported CRISP initiative (2021-2024) on crisis response through semantic data pooling.

Wachs contributes to the Complexity Science Hub Vienna and leads Corvinus University's upcoming MSc in Social Data Science (launching 2025), positioning him at the forefront of computational social science education in Central Europe.
