Far North Queensland is a spectacular place to grow up, with a backyard full of beautiful landscapes. As an inquisitive child growing up I had always shown a keen interest in rocks and how the world works, much to the annoyance of my parents. I have often been told stories where I have asked "Where do mountains come from?" or "What type of rock is this?". Often unsatisfied with their replies, it followed, then, that I chose a career in Geology.
In 2014 I completed a Bachelors Degree with Class I Honours (so I now have a pretty good idea about where mountains come from and a long list of rocks that I know). My research included three formations within Porcupine Gorge, central North Queensland. My primary focus was the Blantyre Sandstone, and I was able to determine the sedimentary history of this unit. Luckily, the rocks in my field area were very forthcoming with their stories, leading to success in my research, encouraging me to pursue human/rock relations as a hobby. I now continue my academic pursuits through a PhD, relying on a mutual understanding with the rocks.
The crux of my PhD research is to understand the sedimentology of the Hughenden region in central North Queensland, and to determine the provenance of Mesozoic sedimentary formations from within the Great Artesian Basin in eastern Australia in an attempt to reconstruct and date the tectonic events that have shaped the region. This has led me to some of the most beautiful landscapes in Australia, including a return to Porcupine Gorge, as well as visiting Carnarvon Gorge and the Gregory Range in Queensland. I have also explored Jurassic rocks in Geraldton, Western Australia, on the hunt for dinosaur or marine reptile fossils.
A side enterprise involves the discovery and description of the oldest known fossil evidence of fungus farming amongst insects. This spectacular fossil was found as part of the East African Rift Project in Tanzania and has been a well received ichnological discovery, published in Plos One and the Australasian Science magazine (see publications below or in the publications page on this website).
