Behavioural Data Scientist
Laura Maria
Fetz.
I bring psychology, education, and data science together to explore human behaviour — through statistical modelling, machine learning, and thoughtful research.

02 / About me
Curiosity,
with a quantitative lens.
I’m an interdisciplinary researcher with master’s degrees in Behavioural Data Science and Child Development & Education from the University of Amsterdam.
My work combines quantitative research, statistical modelling, and machine learning to better understand human behaviour, psychological processes, and educational outcomes.
I enjoy working with complex datasets, exploring methodological challenges, and translating research questions into meaningful analyses.

Understanding people.
Working with data.
I’m interested in how computational and statistical methods can help us understand complex psychological and social phenomena.
Select a language to explore my toolkit.
01 / Statistical modelling
Patterns across people & time
Structural equation modelling, multilevel modelling, longitudinal data analysis, generalised linear mixed models, network analysis, and Monte Carlo simulation.
02 / Psychometrics
Making measurement meaningful
Classical test theory, item response theory, confirmatory factor analysis, measurement invariance, and latent variable modelling.
03 / Machine learning
Prediction with perspective
Supervised learning, classification, regression, natural language processing, model evaluation, and interpretable approaches.
04 / Research practice
From questions to clear findings
Research design, data management, statistical inference, and data visualisation — with an interest in methodological challenges.
06 / Beyond data
There’s a whole world
outside the dataset.
Outside of research and coding, I love travelling, exploring new cultures, learning languages, and discovering good food.
I’m always curious about new places, people, and experiences.
