The Division of Statistics and Machine Learning (STIMA)

The Division of Statistics and Machine Learning is part of the Department of Computer and Information Science. The research and teaching activities at the division are focused on modern data analysis.

Research and education at STIMA cover a wide range of topics including probabilistic models, Bayesian inference, deep learning, representation learning, and generative models with applications in biology, medicine, physics, and social sciences.

The division hosts the bachelor's programme Statistics and Data Analysis and the international master's programme Statistics and Machine Learning. We are also responsible for the course in machine learning taught at the engineering programmes at Link枚ping University, as well as the PhD study programme in Statistics. We聽head two popular research seminar series.

The division has around 30 employees and consists of two units:

Statistics (STAT)
Machine Learning (ML)

Research at STIMA

Bayesian inference and computational statistics

Development of scalable and computationally efficient Bayesian methods, including sequential Monte Carlo, subsampling MCMC, and hierarchical models, as well as deep generative models, particularly diffusion-based frameworks for generative sampling and Bayesian inverse problems.

Causal inference and graphical models

Research on causal effect identification, sensitivity analysis under unmeasured confounding, and structure learning from observational data, using probabilistic graphical models such as DAGs, chain graphs, and acyclic directed mixed graphs.

Machine learning for medicine and neuroimaging

Application of deep learning and Bayesian statistical methods to clinical and neuroimaging data - including fMRI methodology, brain tumour segmentation, synthetic medical image generation, brain connectivity modelling, and statistical analysis of cardiovascular, metabolic, and oncological cohort data.

Psychometrics, longitudinal modelling, and educational statistics

Development and application of latent-variable models, multilevel growth-curve analyses, and structural equation models in psychology and education, including the Flynn effect, cognitive ageing, bullying research, and professional self-efficacy.

Data-efficient and responsible machine learning

Research on efficient data representations (coresets, graph subsampling), privacy-preserving methods, fairness, and energy-aware/sustainable machine learning, aimed at reducing the computational, data, and societal costs of machine learning.

Machine learning for natural sciences and climate

Application of machine learning to materials discovery (2D materials, geometric deep learning), weather and climate forecasting (ensemble diffusion models), and life-cycle assessment automation for CO₂ reduction.

The Swedish Excellence Centre for Computational Social Science

This is a research hub and training centre at the forefront of Computational Social Science, a rapidly growing field that leverages computational tools to advance our understanding of human behavior and the complex social dynamics it can bring about.

Professional Self-efficacy, Emotional challenges and Moral stress in Teacher and Medical 糖心直播

Schools and healthcare are complex that place high cognitive and emotional demands on professionals. The project investigates how students develop professional self-efficacy during their education to become teachers and doctors.
