I find
patterns
in messy things.

I’m Marjan Cugmas — statistician, researcher and university teacher. I work at the intersection of statistical methodology and social science, with a particular weakness for networks, clusters, models and charts that make a complicated idea suddenly click.

Curious by nature.
Statistical by training.

A / 01

Research

I develop and apply statistical methods that reveal structure in complex social data, from clusters and network positions to latent dimensions and regression models. I use these methods to study, e.g., social support and scientific collaboration.

A / 02

Teaching

I primarily teach statistical methodology at the University of Ljubljana and spend a suspicious amount of time finding ways to make difficult ideas visually intuitive without sacrificing technical rigour.

A / 03

Making things

R packages, dashboards, automatically generated reports, slides, tattoo sketches, tiny web experiments and photo archives. I like analysis most when it becomes something tangible.

03 / research

The recurring
questions.

The topics change, but the basic obsession stays fairly constant: what local processes create the larger structure we observe, and how can we measure that structure well?

Social support networks

Who has access to support, who becomes vulnerable, and how support networks shift under major disruptions such as the COVID-19 pandemic.

Scientific collaboration

Longitudinal patterns of collaboration among researchers, doctoral students and mentors, from individual ties to national and European structures.

Online counselling + health communities

Survey methodology, text mining, machine learning and network analysis applied to large-scale online health and counselling data.

Local mechanisms → global network structure

Coleman’s macro–micro–macro model, network evolution, blockmodeling and the connection between local mechanisms and large-scale structure.

Statistical methodology

Developing and evaluating approaches to blockmodeling and partition comparison.

Statistical software

R packages, Shiny dashboards, reproducible reporting and tools that convert statistical work into usable systems.

Research that
became a thing.

A selection of research and applied projects. A broader record of ARIS-funded projects and programmes is available in SICRIS, although some collaborative and applied work is not included there.

Statistics should
be understandable.

Recent teaching spans multivariate analysis, data visualisation and network methodology.

COURSE

Generalized Linear Models

When your dependent variable refuses to behave — binary outcomes, categories, counts or highly asymmetric data — generalized linear models take regression beyond the ordinary linear model.

University of Ljubljana · Applied Statistics MA · 2024–2026
COURSE

Data Visualization + Explorative Data Analysis

How to turn data into visual stories that people can understand and act on — combining analytical thinking, perception, design and storytelling.

University of Ljubljana · Social Informatics MA · 2022–2026Ljubljana Summer School · 2026
COURSE

Foundations of Data Analytics

How to think with data before the methods get complicated — from preparing and exploring data to statistical inference, hypothesis testing and regression.

University of Ljubljana · Social Informatics MA · 2021–2026
COURSE

Multivariate Analysis

When there are too many variables to study one at a time — using methods such as cluster analysis, PCA and factor analysis to simplify data and uncover hidden structure.

There is life
outside the model.

Old-school things, new obsessions.

I’m into 80s aesthetics, analog photography, old electronics, traditional tattoo art, books, hiking, weather and the strange satisfaction of using an object that has more character than efficiency.
