Position & Role in STACCATO
Niall Barron is a Principal Investigator at NIBRT and Professor of Biochemical Engineering in the School of Chemical and Bioprocess Engineering in University College Dublin, Ireland. Main supervisor of ESR2, Co-supervisor of ESR1, ESR3, ESR6.
My groups’ research interests focus on targeted genetic engineering strategies to improve or control the production of recombinant therapeutic proteins from Chinese Hamster Ovary (CHO) cells. Typically this involves profiling of miRNA, mRNA and protein expression and subsequent analysis and integration of these datasets with a view to identifying engineering targets to improve CHO cell phenotypes relevant to the Biopharmaceutical industry. We are interested in developing advanced recombinant DNA engineering strategies for improved phenotypic stability and selection of producer lines. This includes methods for targeted genome modification (using viruses and CRISPR-Cas9 approaches) and directed evolution.
