Technological and scientific advances have pushed the Life sciences into the BIG data era. The increased volume and heterogeneity of available data challenges scientists to master techniques for comprehensive data analysis. Extracting meaningful (biological) information from large datasets is increasingly becoming a challenge in all fields of life sciences. Thus, the ability to select and deploy analysis tools and algorithms has become an indispensable skill for all researchers. In this course, we aim to introduce participants to techniques for comprehensive data analysis of large, heterogeneous datasets and extract relevant information for elucidating biological design principles. The course is modular and focuses on data generation, mining, analysis, data integration, and visualization.
This course is aimed at anyone working with big datasets in the life sciences who has an interest in learning more about tools and possibilities for big data analysis. The course is introductory.
Required knowledge: Basic knowledge of statistics.
Prerequisite: Experience of computer programming would be useful but is not mandatory. Computer practicals will require using R. An R tutorial will be sent in advance to ensure that all participants have the required level.
The aim of this course is to introduce participants to techniques for comprehensive data analysis of big data and to integrate heterogeneous data sets in order to extract relevant information for elucidating the living system. The course is modular and focuses on data generation, mining, analysis, data integration, and visualization.

Lecturers are from the Laboratory of Systems & Synthetic Biology (SSB) and from the Division of Human Nutrition and Health (HNH) from Wageningen University & Research:
- Edoardo Saccenti, PhD (SSB)
- Maria Suarez Diez, PhD (SSB)
- Jasper Koehorst, PhD (SSB)
- Guido Hooiveld, PhD (HNH)
Dr Edoardo Saccenti is an expert on multivariate data analysis. His research focuses on reduction and modelling techniques for large biological data sets using random matrix theory and (sparse) component approaches.
Dr Maria Suarez-Diez has extensive experience in reverse engineering of regulatory networks, metabolic modelling and the combination thereof to gain systems level understanding of the living system. She has also extensive experience in the integration of heterogeneous data sets and in the use of semantic web technologies for data integration and sharing in the life sciences.
Dr Jasper Koehorst has ample experience on infrastructure development for big data applications for bacterial genomics. He is an expert on semantic data integration and on the use of semantic resources in the life sciences
Dr Guido Hooiveld has extensive experience in the use of high throughput, information-dense omics technologies in combination with experiments in suitable models (e.g. cell, animal, and human models). He is an expert in the biological interpretation of complex nutrigenomics datasets and on integration of multi-omics data sets with functional measurements to extract novel biological insights into the molecular effects of nutrients.
