Welcome to the Tietze Lab

Dr. Alesia A. Tietze,  Associate Professor, Senior Lecturer in Medicinal Chemistry, focuses on bioinspired chemical engineering of peptide-based molecules/ materials towards diagnostics and drug delivery. My research team develops novel approaches with the goal of providing access to highly hydrophobic peptides/peptide mimetics, i.e. transmembrane peptides/proteins and venom-derived cysteine-rich peptides. We develop novel conjugation methods, explore SAR properties of novel bioactive peptides, and engineer peptide-based nanosensors.

We are located at the Department of Chemistry and Molecular Biology at the University of Gothenburg, Sweden and are part of the Wallenberg Centre for Molecular and Translational Medicine
