Meet The Team

Professor Geoffrey Faulkner

Group Leader

Geoff was awarded his PhD in computational biology in 2009 from the University of Queensland (UQ) and that year started his lab at the University of Edinburgh, supported by an NHMRC CJ Martin fellowship. He moved back to UQ in 2012, was promoted to full Professor in 2016, and now holds a joint appointment between the Mater Research Institute and the Queensland Brain Institute. Geoff is obsessed with mobile DNA and its impact on genes and genomes across mammalian biology, and is excited to be doing research in an era of rapid advances in genomic technologies. His favourite things about being a group leader are seeing his trainees succeed, getting new experimental results, and occasionally finding time to do some bioinformatics. Geoff is an NHMRC Leadership Fellow and he received the Australian Academy of Science Ruth Stephens Gani Medal in 2016 for his work on retrotransposition in somatic cells.

Dr. Gabriela 0. Bodea

Post Doc

Dr. Gabriela Bodea has been part of the Genome Plasticity and Disease group at Mater Research Institute – UQ since June 2014, when she joined the group being supported by a German Research Foundation (DFG) fellowship. In 2015, she was awarded an NHMRC-ARC Dementia Research Development Fellowship to continue her work on the activity of LINE-1 retrotransposons in dopaminergic neurons. This achievement was a continuation of her PhD awarded in 2014 in the laboratory of  PD Dr. Sandra Blaess (Institute of Reconstructive Neurobiology, University of Bonn, Germany), where she focused on the developmental mechanisms leading to dopaminergic neuron diversity in the mammalian brain. Dr Bodea’s long term research interest is to understand how neuronal diversity is generated in the mammalian brain and how this diversity translates into a different vulnerability to disease.

Dr. Natasha Jansz

Post Doc

Natasha joined the Genome Plasticity and Disease group in January 2021 to study the mechanisms governing expression from proviral DNA. Natasha has a background in molecular epigenetics. She was awarded her PhD in the lab of Professor Marnie Blewitt, at WEHI in Melbourne, Australia in 2018. There, she characterised the structural maintenance of chromosomes protein, Smchd1, in mammalian development. Natasha was awarded a Humboldt Research Fellowship, HFSP Postdoctoral Fellowship, and an EMBO Postdoctoral Fellowship (non-stipendiary) to train at the Institute of Epigenetics and Stem Cells in Munich, Germany, where she studied transposable element function in preimplantation development. Natasha has joined the team of Professor Geoffrey Faulkner, supported by an NHMRC Investigator Grant, to investigate mechanisms underlying endogenous and exogenous retrovirus regulation in infectious and malignant disease.

Dr. Charles Bell

Post Doc

Charles joined the Faulkner lab for his second post-doc in early 2023. Charles received his Bachelor of Science with Honours at the University of Queensland, graduating as a University Medallist. After studying the regulation of early embryonic development in the laboratory of Andrew Perkins, he moved to Melbourne to complete his PhD training. His PhD, entitled “Understanding and manipulating epigenetic regulation in cancer” was awarded in the laboratory of Mark Dawson at the Peter MacCallum Cancer Centre. After receiving his PhD, Charles remained in the Dawson lab for his first post-doc where he established an innovative system to understand how transcription factors function. Charles hopes to continue to develop these tools and techniques to provide further insights into the fundamentals of transcription, and apply them to improve our understanding of how L1 elements and other endogenous retroviruses are regulated.
