About the lab

At the intersection of computer science, AI, and genomics

The Hormozdiari Lab develops innovative combinatorial algorithms and artificial intelligence (AI) methods—including combinatorial optimization, machine learning, and deep learning—to analyze large-scale biological data. Our primary goal is to uncover how genetic variation, particularly understudied structural variation, influences human health, evolution, and disease.

We design computational tools to discover and genotype variants from whole-genome sequencing, assemble genomes de novo, model how variants reshape the three-dimensional structure of the genome, and predict complex phenotypes from genomic data. We apply these methods to complex disorders ranging from autism to cancer.

The lab is based at the UC Davis Genome Center, with affiliations across the Department of Biochemistry & Molecular Medicine, the MIND Institute, and the graduate groups in Computer Science and Integrated Genetics & Genomics.

Research areas

What we work on

Our research spans algorithm design and AI for sequence analysis, together with systems-biology approaches to predicting disease.

Structural variation discovery

Novel computational methods to discover and genotype structural variants from whole-genome sequencing, and to link them to complex disorders such as autism and cancer.

Algorithms · WGS

Pangenome graph analysis

Building, augmenting, and analyzing pangenome graphs that capture variation across many genomes — moving beyond a single linear reference for more complete variant discovery and genotyping.

Graphs · Pangenomes

Structural variation & the 3D genome

Modeling how structural variants disrupt higher-order chromatin organization — TADs, boundaries, and loops — to alter gene regulation in disease.

Hi-C · Chromatin

Modules & pathways in disorders

Network algorithms that identify gene modules and biological pathways contributing to neurodevelopmental and other complex disorders.

Networks · Systems biology

Complex-disorder prediction

Machine-learning classifiers that predict phenotype from rare and common variants and other -omics data, toward accurate disorder prediction.

Machine learning

Open methods & software

We release tools the community can build on — from read mapping and variant discovery to gene-network and prediction frameworks.
