Melinda Ashcroft

Melinda Ashcroft is a current PhD candidate in Bioinformatics and Microbial Genomics. She completed her undergraduate degree in Applied Science (Biotechnology) more than 10 years ago at the Queensland University of Technology. She then spent 7 years working in a customer-focused role before returning to postgraduate study and obtaining her Master of Biotechnology (High Distinction) from the University of Queensland in 2013. Mid-way through her masters, Melinda realised that it was possible to combine her two passions, computers and biology. This progressed into a Masters project on Melanoma genomics before Melinda moved into the Beatson Lab to work on a summer project on data manipulation of the Escherichia coli genome. In 2014 Melinda decided to continue working in Bioinformatics and joined the Beatson Lab group to undertake her PhD. Here her work focuses on the accessory genome in Extraintestinal pathogenic E. coli (ExPEC), with major projects investigating antimicrobial resistant lineages and the evolution and function of methylation using Pacific Biosciences SMRT sequencing technology.

In her spare time, Melinda is involved in organising and participating in a number of social networking and mentoring opportunities for students in molecular biosciences and computational biology. Additionally, Melinda is a tutor for a range of subjects relating to biotechnology, bioinformatics, microbiology and genetics and her interests include science communication and blogging.
