A Spectral Decomposition Framework for Multiscale Nonlinear Dimensionality Reduction
arXiv, 2026
I am a professor for visualization in the Vis Group at the University of Bergen, Norway.
I build visual analytics tools that help people make sense of large, high-dimensional data, usually together with biologists and medical researchers. Right now I am working on dimensionality reduction, on tools for exploring single-cell and spatial omics data, and on how interactive visualization and AI can work hand in hand.
Looking for a master thesis? I have open projects from fundamental to very applied, so if any of this sounds interesting, get in touch and we can find something that fits you.
I gave a keynote at VCBM 2026 in Ljubljana: From Cellular Composition to Tissue Organization: Visual Analytics for Single-Cell and Spatial Data.
Soumyadeep Basu successfully defended his thesis Comparative Visual Analytics for Multi-Modal Single-Cell and Spatial Omics Data at Leiden University today. Supervising his PhD over the past five years has been a real pleasure. Congratulations, Soumya, on this great achievement!
A proud day: Chang Li defended her PhD thesis Visual Analytics for Whole-Brain Spatial Transcriptomics, which I had the pleasure to co-supervise with Boudewijn Lelieveldt, at Leiden University. Congratulations, Chang, and all the best for what comes next!
