Backman develops nanoscale-sensitive optical biophotonics -- including chromatin-sensitive partial-wave spectroscopic (PWS) microscopy, which is label-free and detects mass-density fluctuations of chromatin packing domains below the diffraction limit -- and combines it with super-resolution imaging, electron tomography, and computational genome modeling in his nano-ChIA platform. The lab links this multi-scale nanoscale chromatin imaging to gene-expression physics and has translated the technology into cancer early-detection diagnostics through several spinout companies.
Hylkje Geertsema uses single-molecule super-resolution fluorescence microscopy (TIRF, SMLM, PALM/STORM) to study DNA replication dynamics. Her lab visualises and quantifies individual replication proteins at replication forks in living cells to understand the kinetics and fidelity of DNA copying. Research focuses on measuring spatiotemporal dynamics of protein assemblies during DNA metabolism with nanometre resolution.
Develops microfluidics and imaging-based spatial-omics technologies for high-resolution, high-throughput assays and modeling of complex biological systems, including bottom-up construction of synthetic cells.
Bernd Rieger works on computational super-resolution microscopy and live tissue imaging at the nanoscale. Research directions: (1) single-molecule localization microscopy (SMLM) algorithms and particle fusion; (2) 3D multi-label super-resolution imaging in tissue; (3) deep learning for biological image analysis. ERC grants; NL-BI Dutch Bioimaging consortium.
Sentenac develops computational super-resolution fluorescence microscopy at Institut Fresnel, notably Random Illumination Microscopy (RIM), which reconstructs sub-diffraction images from the statistics (variance) of many speckle-illuminated acquisitions without requiring photoswitchable probes, along with the underlying inverse-problem theory that establishes its resolution limits and robustness for live and thick-sample imaging.
Sjoerd Stallinga develops computational methods and hardware for super-resolution fluorescence microscopy. Research: (1) 3D single-molecule localization microscopy (3D SMLM) in living cells and tissue; (2) structured illumination microscopy (SIM) with noise-controlled reconstruction; (3) Fisher information framework for SMLM localization precision; (4) optical metrology for nanoscale structure characterization. ERC Advanced Grant for 3D super-resolution in living tissue.
