I'm currently a PhD candidate in the department of Biomolecular Medicine at Imperial College London (UK) in Prof. Elaine Holmes lab, my co-supervisors are Prof. Jeremy Nicholson (Imperial College) and Johan Trygg (Umeå University).


My PhD research activities are in the area of Metabolite profiling, Chemometrics and Statistical pattern recognition, with a focus on development and application of statistical pattern recognition methods for the analysis of ‘Omics’ data in biology, e.g. transcriptomics, proteomics and metabonomics.


I have a general interest in supervised learning and statistical data analysis methods, with a focus on modeling of biological data. I'm particularly interested in methods and strategies for data integration and quantitative approaches to biological research in general.

Recent research activities include:

  • Discriminant analysis
  • Kernel based methods for pattern analysis
  • Integrated modeling of data from multiple analytical platforms
  • Modeling of short time series data sets

Other science topic I'm interested in:

  • Statistical Experimental Design
  • Automation and standardization of experimental biology including data analysis and representation of biological data
  • Synthetic biology
  • Open source / access to software and information
