Research Work

Research interests. The areas of research are the theory, development and application of optimization (both global and local), and the interaction of optimization and data analysis. The interests include multiple criteria decision support, dimensionality reduction and visualization of multidimensional data, optimization theory and applications, data mining in databases, neural networks, parallel optimization, and image analysis. A lot of software is designed both for general purposes and for applications. Various problems of computer-aided design have been solved, too. The author of more than 240 scientific publications, two monographs, five textbooks.

 

Internationally recognized research group for visual analysis and dimensionality reduction of multidimensional data has been established and developed in Lithuania. 12 doctoral students successfully defenced their PhD thesis and got doctoral degree under his supervision.
