algorithms

Research topic
Theoretical analyses of algorithms and their practical implementation.

My research interests focus on the theory of algorithms and computational complexity of mathematically formalized problems, in particular, combinatorial optimization problems such as tree pattern matching and graph data mining.

Research topic
Cognitive mechanisms of object recognition in cultural contexts

My recent research focuses on the cognitive mechanisms of reading diagrams such as tables and graphs.

Professor

Research field
cultural phylogenetics, mathematical philology, traditional cultures

Research topic
Reconstructing the past, genealogy of manuscripts, fragrance, tea and flowers, brain waves and music

As bio-phylogenetics reconstructs history with the “ancestor-descendant” relationship, a phylogenetic point of view is necessary in the context of culture and language in order to reconstruct the past. For non-superficial, deep understanding of cultural phenomena, one must have a mathematical viewpoint and experience the actual culture. I teach how to analyze brain waves and music based on data analyses.
