Research interest

We are a growing, young, interdisciplinary team and closely connected to the Pharmaceutical Technology groups of Prof. Heerklotz and Prof. Süss. We believe that we can make a meaningful contribution to a sustainable tomorrow and, motivated by the 17 UN developmental goals, we would like to contribute to 'Good health and Well-being'.


Our Vision

We are aiming for easing access to life-saving, parenterally applied medication for low- and middle-income countries by using the human body as a bioreactor.

Our Mission

We are working on parenteral drug product formulations and device solutions to facilitate product access in countries with limited medical infrastructure. The research group focuses on the technical development of ATMPs (Advanced therapeutic medicinal products) including cell therapeutics and nucleotide-based formats.

We are in particular interested in mRNA therapeutics incorporated into lipid nanoparticles to achieve our vision and use the human body to produce its own medication (preclinical studies: Stadler and Sahin, Nature Medicine 2017, doi: 10.1038/nm.4356 and Rybakova et al.: Mol. Ther. 2019, doi: 10.1016/j.ymthe.2019.05.012).

We address three major challenges for access to parenteral medications in 3rd World countries: (1) the cold chain; (2) aseptic product preparation before administration; and (3) cost of goods. While we do not optimize mRNA constructs, we develop drug product solutions for parenteral delivery with adequate long-term stabilization.

Open Positions

Master student

We are seeking a highly motivated Master student interested in studying mRNA or cell therapeutics. The candidate should habe a Bachelor degree or equivalent in the area of Pharmaceutical Sciences, or related biology and chemical sciences. Previous experience in a laboratory setting is required. For fullest consideration, applicants should send (1) a cover letter with a brief statement of interests, and (2) a CV to: Andrea Allmendinger.
