The Bioinformatics Hub currently has two full-time staff members, and one position held in conjunction with the Robinson Research Institute.

Co-ordinator - Steve Pederson

As the inaugural co-ordinator of the Bioinformatics Hub, Steve began the position in 2014. He has been involved as an educator outside of Science for over 20 years, and brings this experience to the training workshops run at regular intervals.

With a strong background in genetics and statistics, Steve is proficient in R, C and bash scripting. His research interests include regulation of gene expression, and downstream analysis of gene sets.

Post Doctoral Bioinformatician - Hien To

With a strong background in applied mathematics, Dr To received her PhD in 2011 from Université Paris Diderot - Paris 7.

She has been working on algorithm aspects of constructing phylogenies, reconciling gene trees within species phylogenies to predict gene losses, duplications or transfers; and on molecular dating methods. Her research interests include of developments of algorithms, and modelling in bioinformatics.

Post Doctoral Bioinformatician - Jimmy Breen

Jimmy is a Bioinformatician and genomic researcher with 10 years expertise. Starting research life in agricultural genomics, he gained his PhD in assembling complex (>16Gb/>70% repetitive DNA) plant genomes as part of the International Wheat Genome Sequencing Consortium. His Post doctoral position in Switzerland (plant/fungal disease resistance genes and physical map assembly) was followed by QC and data analysis for AGRF in Brisbane.

His previous role was at the Australian Centre for Ancient DNA and School of Agriculture, Food and Wine, working with Professor Alan Cooper on a range of projects including:

  • ancient DNA sequencing of 5,000 year old plant material from Armenia
  • metagenomics and NGS pipeline development for the analysis of dental calculus from Neandertals and other ancient Hominins,
  • developing an ancient human genome data repository called the Online Ancient Genome Repository (OAGR;
  • epigenetic profiling of fungal pathogens (Botrytis cinerea) and Shiraz plants in the Barossa Valley.

Jimmy is also the lecturer for the University of Adelaide’s Bioinformatics and Systems Modelling unit as part of the Master of Biotechnology course.
