Job offers

We normally have open positions for medical doctoral students and master students. If you are interested in working in a highly interactive team within an interdisciplinary environment using reverse genetic approaches, state-of-the-art microscopy techniques and are not afraid of new challenges and biophysical methods, please send us your CV, 2 letters of recommendation and a 1-page statement of motivation within a single pdf. We also usually have some vacancies for short term stays of a minimum of 6 weeks. For those send an informal enquiry to "fratsch(at)gmail.com".

Projects
Visualising malaria transmission

Malaria is transmitted during the blood meal of the Anopheles mosquito, when Plasmodium sporozoites are injected into the skin. These sporozoites are highly motile using a unique type of motility system allowing them to move within the tissue in order to reach the blood circulation. This motility system is also important for the invasion of a variety of cell types at different stages of the Plasmodium life cycle thus being essential for the successful progression of the infectious cycle of the malaria parasite.

Four projects deal with different aspects of sporozoite biology. One project investigates Lyme disease borrelia.

Project 1: Deletion and modification of genes involved in parasite gliding motility

Project 2: Investigating the biophysical basis of gliding by measuring the forces that sporozoites generate on flexible and nano-patterned substrates as well as with laser traps

Project 3: Quantitative in vivo and in vitro imaging of sporozoites and their interaction with cells and substrates

Project 4: Investigation of sporozoite formation in 3D at high resolution using cryo-electron tomography, correlative light and electron microscopy

Project 5: Investigation of Lyme disease Borrelia

Publication in Nature Physics

(24 November 2025)

New findings by scientists in our department (Frischknecht lab) together with colleagues from the local Institute for Theoretical Physics and Johns Hopkins University in the USA: Malaria parasites move on right-handed helices, which is made possible by a previously unexplained asymmetry in the parasite's body structure. These findings could in turn be helpful in testing new drugs and vaccines.

If you would like more information about the research, it is available in the journal Nature Physics:

L. Lettermann, M. Singer, S. Steinbrück, F. Ziebert, S. Kanatani, P. Sinnis, F. Frischknecht, U. S. Schwarz: Chirality of malaria parasites determines their motion patterns. Nature Physics (November 24, 2025), https://doi.org/10.1038/s41567-025-03096-0

Interview with F. Frischknecht

(19 September 2024)

On the occasion of the annual report 2023 of Heidelberg University hospital Prof. Till Bärnighausen (Heidelberg Institute for Global Health) and our group leader Prof. Friedrich Frischknecht were interviewed on the fascinating topic of 'Mosquitoes and Men'. A very interesting insight, especially as the infection route of malaria is also explained. The complete annual report 2023 is available here
