Research Projects:

• Liquid STEM. A new method for real-time electron microscopy imaging of bacterial and eukaryotic cells in liquid with nanometer spatial resolution, using a micro-fluidics flow cell with electron transparent windows.
• 3D STEM. A new 3-dimensional aberration corrected scanning transmission electron microscope technique of biological samples based on the principles of confocal microscopy, as possible alternative for tomography.
• In situ STEM. A unique platform for in situ STEM for high resolution imaging of solid:gas interfaces at atmospheric pressure and high temperatures, or in liquids.
• Electron source. A new high brightness electron source for STEM using carbon nanotubes. The new sources should result in much faster STEM imaging, as needed for time-resolved imaging.
