Bio
Joachim received his Ph.D. in microfluidics from the University of Oslo and was a postdoc at Stanford and at UCSB to learn about interfacial flows and miscible fluids. He then worked as a teacher of fluid mechanics at the Norwegian University of Life Sciences, and developed "kitchen flows" as an affordable and accessible learning strategy. Back at the University of Oslo, he now works in a multi-disciplinary team to unravel how cells work in concert to form organs.

Utilizing light-sheet microscopy
As postdoc in the UiO:LifeScience ITOM-project, Joachim built his own light-sheet microscope to characterize how early mammalian embryo models (gastruloids) grow and develop, and how the first organs form. Especially, he is interested in how cells self-organize and orchestrate their motion to form tissue. To explain the underpinning dynamics, he couples his experiments with 3D simulations.

To fully utilize light-sheet imaging, Joachim also studies collective cell migration in zebrafish with members of the Camila Esguerra Group and the cells' own recycling system (autophagy) in Drosophila embryos in collaboration with Helene Kn?velsrud.

Collaborators
Dag K. Dysthe (Dept. Physics) oversees the experimental investigation, and Xian Hu helps out with 3D rendering. To explain the dynamics of collective cell migration, Dr. Richard Ho from Luiza Angheluta-Bauer's group conducts complementary simulations. Postdocs Sergei Ponomartcev and Nathalia Smirnova from Hybrid Technology Hub SFF provide stained gastruloid samples. Steven Ray Haakon Wilson at the Chemistry Department contributes with mass spectrometry measurements. Joachim reports to the center director at RITMO SFF Alexander Refsum Jensenius.
Funding
The ITOM project is funded by UiO:Life Science.
