My fist contact with the exciting world of polymers for biomedical applications was during a research internship at the University Medical Centre Mainz, Department of Dermatology, where I investigated the cellular uptake of allergen loaded poly(ethelyne glycol) (PEG) based nanoparticles. Working on the border between synthetic polymer chemistry and immunology fascinated me to such an extent, that I joined the group of Prof. Frey at the Department of Organic Chemistry, JGU Mainz, to write my master thesis about this project. My PhD thesis deals with the synthesis of cleavable PEGs for biomedical applications. At this point, I would like to take the chance to thank Prof. Sajkiewicz for the opportunity to join his group and to expand my knowledge of the processing of polymeric materials by electrospinning.
