Research

The merger of statistics and informatics inside the GSEM recognizes that statistics, to be effective in practice, cannot live without informatics, and informatics, to go beyond information or say, data management with some descriptive statistics, needs to get enriched by sound data analytical methods. The modern conception of data science as a discipline is often attributed to William S. Cleveland, a Professor of Statistics and Computer Science at Purdue University. In its original definition, statistics and informatics are the fundamental pillars on which data science is based.

Members of the Institute publish scientific work in top journals that range from information systems to fundamental statistics and have a special focus on applied research areas such as environmental sciences, financial econometrics, health, engineering, psychology, etc.

Regarding statistics, our researchers have expertise in robust inference, extreme events, small sample inference, indirect inference, non-parametric statistics, model selection, time series analysis, latent variable and mixture models, non-Euclidian and functional data analysis, etc.

Our researchers more tailored to informatics are strongly involved in industrial technology transfer projects in domains as diverse as formal models of information visualization in 3D virtual environments, services innovation, large-scale services, indoor positioning and navigation systems, services for seniors, mobile sensors: smartphone, smartwatch, wristband, and other wearables, and algebraic operations for the management of knowledge resources.

The Institute's strong involvement in interdisciplinary think groups places it at the forefront of the technology watch in Information Science and various areas of Statistics in Switzerland.
