Project description 

Third-cycle subject: Computer science

We are looking for highly-qualified and motivated individuals to pursue a PhD in the area of data science. The prospect PhD students will join a newly-established research team in KTH led by professor Aristides Gionis (https://www.kth.se/profile/argioni/). The research team focuses on developing novel methods to extract knowledge from data, modeling large-scale complex systems, and exploring new application areas in data science. Emphasis is given in the areas of graph mining, social-network analysis, modeling of information networks and social-network dynamics, as well as in emerging domains, such as interpretable AI. The work combines foundational research in algorithms with development of novel applications.

The advertised positions are funded by Wallenberg AI, Autonomous Systems and Software Program (WASP), Sweden's largest individual research program that provides a platform for academic research and education, fostering interaction with Sweden's leading companies. Funding is also provided by an ambitious 5-year European Research Council (ERC) Advanced Grant titled REBOUND, which aims to study the phenomena of polarization and echo chambers in online media, and develop methods to mitigate these phenomena.

Successful applicants should have completed successfully, or expected to complete, a Master of Science degree, and have strong background in algorithmic design, data mining, machine learning, and combinatorial optimization. Doctoral students are expected to be able to publish high-quality papers and develop research prototypes.


The doctoral students will be placed at the Royal Institute of Techology and supervised by professor Aristides Gionis.
