Prof. Peer’s work was among the first to demonstrate systemic delivery of RNA molecules using targeted nanocarriers to the immune system and he pioneered the use of RNA interference for drug discovery in immune cells. In addition, his lab was the first to show systemic ,cell- specific delivery of modified mRNA expressing therapeutic proteins that has enormous implications in cancer, inflammation and infectious diseases. Prof. Peer is one of the pioneers in the use of molecular medicines (gene silencing, gene expression and gene editing) for therapeutics and diseases management.
