Research

Our research interests lie at the interface of nanotechnology and cellular biophysics, and focus on the physics of signaling at the cell membrane. Some of us develop and investigate thermo-magnetic remote stimulation of proteins and cells using nanotechnology to study signaling networks. Others in our group investigate the cell membrane ultra-structure and how it modulates cell signaling for which we have developed two methods to image the nanoscale structure. Currently, we investigate how temperature, calcium concentration, protein-dimerization and cholesterol influence the ultrastructure, and how this structure modulates immune cell signaling.

More details are here:
1. Local magnetic nanoparticle heating for protein and cell stimulation
2. Thermal noise imaging to resolve membrane ultra-structure
3. bimFCS - studying the influence of membrane ultra-structure on immune cell signaling:
- How do adjuvants or fever help immune signaling?
- How does Ca++ influence membrane structure?

Post-doc and Student Opportunities

We have several NIH- and HFSP-funded post-doctoral positions available. We are looking for one or two people with backgrounds in Neuroscience, Bioengineering or Biophysics to join our efforts in thermomagnetic stiumulation of cells. In addition, we want a person with Biophysics or Immunology background to join our studies of the effects of adjuvants on the cell. Please apply with your CV to Arnd Pralle.
We are always looking for motivated, hard-working graduate and undergraduate students to join us. Please email Arnd Pralle for more information.
