Di Genoma Lab · Universidad de O'Higgins

Computational genomics for cancer, population diversity, and long-read biology.

Di Genoma Lab develops algorithms, sequencing workflows, and reproducible software to study tumor evolution, structural variation, genome assembly, and Chilean genomic diversity. We combine sequencing, high-performance computing, and method development inside one research group.

Research

Programs built around hard biological questions and strong computational methods

Our work sits at the intersection of cancer genomics, long-read technologies, algorithm design, and population-scale analysis. We prioritize methods that can survive contact with real data and real collaborators.

01

Cancer genomics

We investigate tumor evolution through structural variation, copy-number profiles, fusion detection, ecDNA, and multi-omic analysis with a focus on clinically relevant and underrepresented cancer cohorts.

Somatic SV Copy number Multi-omics Rare cancers
02

Genome technologies

We use long-read and hybrid sequencing to resolve assemblies, complex loci, haplotypes, epigenetic marks, and genomic regions that remain difficult to interpret with standard short-read approaches.

Nanopore Hybrid assembly Haplotype phasing Epigenomics
03

Population and comparative genomics

We study Chilean genomic diversity, metagenomic communities, phylogenomics, and evolutionary processes through scalable computation and reproducible statistical analysis.

Current initiatives

Work streams that define the lab right now

These are the projects that best describe the group’s current profile: method development, Chilean genomics, and cancer-focused translational analysis.

A

Reference genome for Chile

Building haplotype-resolved genomic resources to better represent Chilean population diversity and improve downstream clinical and research interpretation.

B

Complex mutational processes in cancer

Characterizing structural complexity, copy-number change, and multi-omic tumor states in prevalent and underrepresented Chilean cancer cohorts.

C

Hybrid assembly and scalable genomics software

Designing fast, portable algorithms and workflows for genome assembly, metagenomic reconstruction, and production-scale genomic computing.

Platforms

Integrated sequencing and compute infrastructure

The group runs local sequencing and high-performance computing resources so projects can move directly from raw signal to interpretation without fragile handoffs or ad hoc environments.

People

A compact team with deep overlap between biology, algorithms, and infrastructure

The group combines bioinformatics, engineering, genomics, and multi-omics analysis. We build methods, operate infrastructure, and work directly with biological questions rather than separating those roles.
