Nikolaj Tatti

Nikolaj Tatti is a Visiting Professor at Aalto University's Department of Computer Science, affiliated with the Helsinki Institute for Information Technology (HIIT) and the Adj. Prof. Gionis Aris research group. His work focuses on algorithmic analysis of temporal networks and graph theory.

Research Interests:

• Temporal network analysis
• Graph decomposition and density
• Segmentation algorithms
• Pattern discovery in time-series data
• Interactive data analysis frameworks

Publication Trends (2018-2021): Research spans Temporal Networks (dynamic hierarchies, cascade reconstruction), Graph Theory (density, decomposition), and Data Mining (periodic patterns, event detection). Collaborative work with Aris Gionis and Polina Rozenshtein dominates his publications.

Technical Collaborations: Works with multidisciplinary teams including researchers from ACM Transactions on Knowledge Discovery and IEEE conferences.
