I'm a computational biologist finishing my Ph.D. in Bioinformatics at Dalhousie University (defense June 2026), based in Montréal, QC. My work sits at the intersection of genomics, statistical modeling, and large-scale biological data analysis and I'm actively transitioning toward human health, cancer genomics, and clinical bioinformatics research.
My doctoral research involved building and analyzing one of the most comprehensive long-term microbial ecology datasets in a temperate ecosystem: 9.5 years of weekly sampling across multiple depths, integrating 16S rRNA amplicon sequencing with environmental covariates.
Core methods I use regularly:
- Amplicon sequencing pipelines: QIIME2, DADA2, VSEARCH, SILVA
- Co-occurrence network analysis: SparCC, igraph (136 networks built and validated)
- Statistical modeling: GLMs, mixed-effects models, FDR correction (BH), permutation testing, longitudinal multivariate analysis
- Ordination & diversity: PCoA, NMDS, PCA, alpha/beta diversity (phyloseq, vegan)
- Phylogenetics: Maximum likelihood and Bayesian tree building (IQ-TREE, RAxML, ape)
- Data visualization: ggplot2, matplotlib, seaborn — publication-quality figures
- Reproducible workflows: Git, Snakemake, SLURM, Compute Canada HPC, AWS
Languages: Python (pandas, NumPy, scikit-learn) · R (tidyverse, ggplot2, phyloseq, vegan) · Bash
