Research & Activities


We are passionate about developing new algorithms, machine learning and deep learning methods, and their applications to genomics, metagenomics and cancer research. Some of the current projects in the lab include characterizing human genomes and metagenomes sequenced by exciting new technologies, quantifying cancer evolution, study of tumor heterogeneity using genomics and digital pathology images.

Structural Variation

Developing algorithms for characterizing structural variations focused on complex and repetitive elements, rare variants and clinical relevant variants.

Tumor Heterogeneity

Quantifying cancer evolution in multiple samples and reconstruction of tumor lineage trees using novel computational methods. Also, building deep learning based classifiers to discriminate heterogeneous sample, using imaging data.

Metagenomics

Advancing computational methods in metagenomics for the purpose of deconvolving mixtures, discovering variants and de novo assembly.

Publications


Below you can see some highlights of our published work. Please also check publications page →

1000 Genomes Project

A catalog of human genome variations in population-scale.

Bioinformatics

Various methods in Bioinformatics and/or ISMB conferences. Algorithms for Next Generation Sequencing, Structural Variation discovery, tumor heterogeneity and Protein-protein intraction prediction.

Handling Multiple Sequenced Genomes

The CommonLAW package presented on the cover of Genome Research introduces novel combinatorial formulations and algorithms for structural variation discovery among a number of sequenced donor genomes, with the help of a complete reference genome. CommonLAW significantly reduces the false positive rate in detecting structural variation events when compared with conventional methods.
