ABOUT ME
Scientist and data analyst with a PhD in cognitive neuroscience, specializing in statistical computing, machine learning, and NLP.
Scientist and data analyst with a PhD in cognitive neuroscience, specializing in statistical computing, machine learning, and NLP.

Hello! My name is Alex and I am a cognitive neuroscientist with a background in statistical computing, machine learning, and natural language processing. I work extensively in both R and Python, and I know how frustrating (and rewarding!) learning a new programming language can be.

I really enjoy teaching, and I’d love to work with you to build your coding confidence and help you solve your data or programming challenges. I can support you with:

  • Learning to code in R or Python — syntax, workflow, and best practices
  • Data wrangling & visualization (tidyverse, pandas, ggplot2, matplotlib, plotly)
  • Frequentist & Bayesian statistics (mixed-effects models, GLMs, brms, Stan, PyMC)
  • Machine learning (from fundamentals to model tuning and evaluation)
  • Natural language processing (NLP) — text preprocessing, embeddings, modeling
  • Reproducible workflows (RMarkdown, Quarto, Jupyter, Git/GitHub)

Whether you're just getting started or working through an advanced project, I’ll meet you where you are and help you take the next step with clarity and confidence.
