Bioinformatician & Biostatistician | R, Python, SPSS

If you have research data that needs rigorous analysis, whether it's sequencing data, a manuscript, a thesis or a survey study, I can take it from raw files to results you can defend to reviewers. I'm a bioinformatician and biostatistician, currently doing a PhD in life science research at the University of Pavia, Italy, with an MPhil in Bioinformatics. My PhD work is single-cell transcriptomics: integrating scRNA-seq time courses across batches (Seurat, Harmony), trajectory and pseudotime analysis (Slingshot, tradeSeq), pseudobulk differential expression, and cross-species comparison of extracellular-matrix genes. On Upwork I've completed 60+ projects for researchers, biotech teams and small businesses. What I help with Transcriptomics & bioinformatics: bulk and single-cell RNA-seq analysis, differential expression, GO/KEGG enrichment, gene and protein annotation, UniProt ID mapping, genomic analyses such as runs of homozygosity, drug repurposing and binding-site analysis. Biostatistics & research statistics: choosing the right test for your design, regression, factor mixture models in R, SPSS analysis, pre/post survey studies, and clear results sections for manuscripts. Data cleaning, automation & dashboards: messy spreadsheets turned into reliable Excel or Google Sheets tools, Python scripts, and inventory or budget dashboards. Recent Upwork projects - Drug repurposing and neurodegeneration bioinformatics (one client, three contracts) - Runs of homozygosity calculation on genomic data - Factor mixture model in R; statistical analysis of a pre/post training survey - Gene and protein name matching with UniProt IDs - Inventory management dashboard (ongoing) How I work: I check the data and study design before running anything, use methods I can justify from the literature, and deliver reproducible code with a plain-language summary of what the results do and don't show. Send me a short description of your data and your question, and I'll tell you honestly whether I'm the right fit.
