Research Interests

My research combines statistical inference on latent class models with computationally intensive applications. I have worked extensively on estimating mixture models both from Bayesian and frequentist perspectives. My PhD thesis proposed a solution to the label switching problem in Bayesian analysis of mixtures of distributions as well as a modification of the reversible jump MCMC algorithm for univariate normal mixtures. As a post-doc researcher at URGV plant genomic unit I developed an initialization scheme of the EM algorithm for the efficient estimation of Poisson GLM mixtures (research project: Unsupervised clustering of RNA-Sequencing data). I worked for six years at the University of Manchester with Professor Magnus Rattray at projects of Bayesian Inference and Statistical Bioinformatics, such as the development of Bayesian methods for estimating transcript expression and performing differential expression analysis in next generation sequencing data, clustering biomedical data and inferring change-points in replicated time-series. Currently, I'm working on model-based clustering of high-dimensional data and the identifiability of Bayesian Factor Analytic Models.
