Hi, I'm Sara Álvarez 👋

Bioinformatics & Biostatistics

MSc in Bioinformatics & Biostatistics with an interest in computational biology, statistical modelling and biological data analysis.

I use R and Python to explore, analyse and visualize scientific data, with a particular interest in genomics and reproducible research.

🔬 What I work with

  • 🧬 Gene-expression and genomic data
  • 📊 Statistical modelling and regression
  • 📈 Exploratory data analysis and visualization
  • 🐍 Python for scientific computing
  • 📐 R for statistical analysis
  • 🔬 PCA and batch-effect analysis
  • 📓 Jupyter Notebook & R Markdown
