My research focuses on studying the topological organization of the human brain network, in health and disease. We map and study the human connectome, the ‘road map of the human brain’ and how complex brain function and disfunction may arise from the topological network properties of the human brain network. With my background I bridge psychology, neuroimaging, mathematics, informatics and medicine.
Principles of wiring of the human connectome
A central theme of the work in my group is to find natural rules that govern the efficient organisation of brain networks. I hypothesise the existence of basic ‘principles of wiring’ that define the topological organization of the human connectome, and study how these principles are associated to brain function and brain disfunction in several neurological and psychiatric disorders.
We particularly like to examine the role of central connected hubs in nervous systems (one of the believed ‘principles of wiring’) and how they form a central rich-club core in the human brain. We examine the brain’s rich club in relationship to genetics, to behaviour, to brain dynamics, in relationship to various brain disorders, and during human brain evolution.
A major focus of our research is on linking brain networks to other fields of neuroscience: These include
- imaging-genetics, in which we link aspects of genetics (e.g. candidate genes, GWAS, gene-expression) to brain connectivity, in health, disease and development. This with the goal to elucidate the genetic underpinnings of the hypothesised ‘principles of wiring’
- cross-disorder connectomics, in which we examine relationships of connectome alterations across different brain disorders
- multi-scale connectomics, in which we link micro- and macroscale features of neural connectivity in health, disease and brain development
- comparative connectomics, in which we aim to bridge connectome properties across different species and search for commonalities and differences in connectome organization between species.
Oh, and of course(!), we have great joy in linking and bridging these different topics as much as possible….
A major research interest of our group is also to develop new methods for MRI connectome research and to explore the usability of AI (e.g. deep learning, classification, data analytics) approaches to medical data, combining all sorts of data including genetics, imaging, questionnaires and multiple other (brain) traits to search for new biomarkers for disease.
I am a handling associate editor for Human Brain Mapping, Network Neuroscience and a member of the Editorial Board of Neuroimage. I am actively involved in several connectome workshops at international conferences and international summerschools on brain network analysis.

This paper was the first in which we linked cortical gene expression profiles to macroscale connectivity patters in context of schizophrenia. We identified overlapping patterns of gene expression and disconnectivity and hypothesized new risk-genes for schizophrenia.
