Academic interests

High dimensional statistics, dimension reduction techniques, penalized regression, data integration methodologies and applications in genetics and biology

Courses taught

Background

My doctoral thesis dealt with the use of principal component analysis in genomics, in particular, consistency issues in high-dimensional data, measurement error and integration of different genetic data types.
