Research interests

Dr Paul Pace previously worked at Imperial College of Science and Technology in London, before moving to the Laboratory of Molecular Biology in Cambridge, where he obtained his PhD studying DNA repair mechanisms.

His expertise is in molecular biology (cloning, mutagenesis, CRISPR applications), protein biochemistry (protein expression and purification, antibody generation and purification, immunocytochemistry, immunoprecipitation, analytical methods) and cell biology (cell culture, transfection, lentiviral expression). He teaches part of the BBiomedSc(Hons) programme, has supervised two summer students, and currently co-supervises two PhD students.

His current projects include studying the biochemistry of peroxiredoxins, including their roles in cell signalling, including the redox regulation of phosphorylation-dependent cell migration and transformation in cancer.
