I am currently working on information retrieval with particular focus on retrieval of experiments and retrieval of metagenomic samples. I have also been exploring probabilistic methods for matrix factorization, in particular archetypal analysis. During my PhD, I worked on nonparametric measures of independence, dependence, conditional independence, and conditional dependence, and their applications in independent component analysis, feature selection, Granger causal inference and spike train analysis. I am also interested in designing strictly positive definite kernels on spike trains for neural decoding and hypothesis testing.
