Unit

Powering the analysis and interpretation of complex genomic datasets that underpin CERI’s surveillance and research activities — from raw sequences to actionable public health interventions.

What the Unit
Specialises In

EXP · 01
Computational Pipelines

Building and maintaining end-to-end computational pipelines that transform raw sequencing outputs into validated, analysis-ready datasets at scale.

Nextflow Snakemake Docker HPC
EXP · 02
Genome Assembly

De novo and reference-guided assembly of viral and bacterial genomes from short and long-read sequencing platforms including Illumina and Oxford Nanopore.

SPAdes Flye Medaka DRAGEN
EXP · 03
Phylogenetics

Inferring evolutionary relationships and tracing pathogen transmission using Bayesian and maximum-likelihood phylogenetic frameworks.

BEAST2 IQ-TREE Nextstrain Pangolin
EXP · 04
Real-Time Surveillance

Continuous monitoring of outbreak dynamics through integrated genomic and epidemiological analysis, supporting national and continental health authorities.

From Sequence
to Intervention

STEP · 01
Sample & Sequencing

Clinical and environmental samples processed through Illumina, ONT GridIon, and Sanger platforms.

STEP · 02
QC & Assembly

Quality filtering, adapter trimming, and genome assembly using validated, reproducible pipelines.

STEP · 03
Phylogenetic Analysis

Evolutionary inference, clade assignment, and transmission cluster detection.

STEP · 04
Epidemiological Integration

Linking genomic data with clinical, geographic, and temporal metadata for outbreak context.

STEP · 05
Public Health Action

Insights delivered to health authorities, published, and integrated into surveillance dashboards.
