Natalia Bochkina's home page

I am a postdoc in the Biostatistics Group in the Department of Epidemiology and Public Health at Imperial College and member of BAIR group (on a Wellcome Trust grant).

Current areas of research.

1.     Differential expression for microarray gene expression data.

2.     Mixture modelling in the fully Bayesian framework.

3.     Bayesian approach in wavelet estimation.
