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 Metabolic 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.

BioSysBio 2008

The BioSysBio conference will be held at Imperial College in 2008. The IET BioSysBio Organising Committee welcomes contributions in the fields of Synthetic Biology, Systems Biology and Bioinformatics.

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
