[1] She has travelled widely, including to Norway and Antarctica, to conduct her research and uses a variety of biochemical and bioinformatic methods to study the collected enzymes.
She spent her first two years there working as a research fellow and principal investigator,[1] before being appointed a senior lecturer in the Biomedical, and Molecular and Cellular Biology Departments.
[2][7] In 2021, she was admitted into the Maurice Wilkins Centre for Molecular Biodiscovery, which consists of established scientists in New Zealand whose research targets serious human diseases.
[10] These organisms are of interest because they produce enzymes called extremozymes, which are functional under extreme conditions and are applicable in many different fields,[11] including biotechnology and medicine.
[13] In 2020, Williamson was awarded the Rutherford Discovery Fellowship for her research titled "In extremis: how bacteria replicate, repair and diversify their genomes in challenging environments".
[15] Williamson and her team suggest that this variation from typical bacterial replication enzymes could be an adaptation brought on by the extreme environmental conditions.
