Statistics and psychometrics: item response theory, nominal response models, network models, causal inference in evaluation designs
Machine learning and NLP: fine-tuning transformer encoders, multi-task learning, Monte Carlo evaluation designs; PyTorch, 🤗 transformers, Hugging Face Hub
Programming: R (package development, Shiny), Python (PyTorch, 🤗 transformers), JavaScript, LaTeX
Software engineering: designing and running larger systems end to end, from architecture and package APIs to testing, continuous integration, and releases; spotting cross-cutting problems early and fixing them at the root rather than case by case
Reproducible reporting: Quarto and R Markdown pipelines that turn survey data pulled through APIs into automated PDF and HTML reports for schools and funders, at scale
Neuroscience and cognitive science: the field I originally headed toward, through a research assistantship at the National Institute of Mental Health, a long-term internship at the General University Hospital in Prague (VFN), and both degree theses on neuropsychological assessment; I still keep up with it
Languages: Czech (native), English, French

Mentor of a high-school research project (SOČ, the Czech secondary-school research competition) on machine-learning prediction of listening-item difficulty, presented as posters at IMPS 2024 and EAM 2025 (Martinek, Netík, & Martinková)

Psychometric Society (since 2021)
International Society for Clinical Biostatistics (since 2021)
