The position is fully funded by the Vienna Science and Technology Fund (WWTF) and hosted at the Faculty of Physics, University of Vienna — a collaborative environment bridging soft and living matter.

Group page: somexlab.github.io

We are looking for:

PhD candidates with training in two or more of:
— rheology
— biophysics
— quantitative microscopy

or

Postdocs with independence and a strong track record in these areas.

Your main activities would include:

• Preparing and optimizing biomimetic systems
• Performing quantitative imaging and mechanical measurements
• Developing instrumentation at the interface of rheology & optics
• Building analysis workflows and simple models

We will build and apply new opto-rheological and rheomicroscopy tools to study:

• Biomimetic emulsions and vesicle systems
• Zebrafish gastruloids

In collaboration with:
— @dianapinheiro.bsky.social (IMP Vienna)
— @ehannezo.bsky.social (ISTA)

You would join an interdisciplinary team working at the intersection of:

• Experimental soft-matter physics
• Developmental biology
• Biophysics theory

Our central question: How do physical forces and molecular mechanosensing define the material properties of living tissues?

Thank you Conrad! Your opinion and feedback is very much appreciated!

We hope this guide will make DDM as common as DLS in soft-matter and biological labs.

Give it a try, share your results, and let’s make DDM part of every microscope’s toolkit!

fastDDM comes with tutorial on using DDM to study:

- Colloidal suspensions
- Bacteria and active swimmers
- Microrheology of complex fluids
- Cells and tissues

The tutorial includes examples and notebooks for all of these.

We also introduce fastDDM — a new, open-source, high-performance implementation that makes DDM thousands of times faster and easy to use on large datasets.

🧰 Free, transparent, and ready for your next project.

We walk you through the complete pipeline ⬇️

🎥 Video acquisition → ⚡ Fourier analysis → 📊 Fitting → 🔍 Physical parameters

The same logic works for bright-field, phase-contrast, fluorescence microscopy, and beyond…

DDM lets you turn any microscopy video into a scattering experiment, revealing the dynamics of colloids, proteins, liquid crystals, foams, emulsions, cells, bacteria, or active matter directly from image sequences.

It’s like DLS, but with a microscope and a movie.
