I'm an Australian completing my PhD in France. I use simulations and experiments to understand the interactions between ambient ionising radiation and living systems.
I also spend part of my time doing full stack web development at Hello Uni, working on their online revision platform.
Everyday, we and every other living creature on the planet feels a small bit of radiation. This radiation comes from both space and the earth around us.
Using experiments conducted in the Modane Underground Laboratory together with computer simulations of how radiation interacts with cells and DNA, I am measuring whether radiation is an important agent in the evolution of life.
I graduated from Monash University in January 2014 with first class honours in both of my degree programs, the Bachelor of Aerospace Engineering and the Bachelor of Science (Physics, Maths).
I've held paid research positions regularly since 2010, and have experience communicating scientific ideas as both a teaching associate and public science lecturer at the Parkes Radio Telescope.
From astrophysics to microbiology, I've touched on a number of subjects. Currently I'm working on my PhD exploring the interactions between radiation and evolution.
Other projects I've worked on include simulations of quantum fluids, unmanned aerial vehicals and the development of x-ray detectors.

Radiation affects DNA. There is no doubt about it, but does the small amount of radiation we experience on a daily basis impact the evolution of life? That is the question I'm working to answer.
Working in different radiation environments, I evolve bacteria over multiple generations to see how soon mutations manifest in the population.
Using the Geant4-DNA toolkit, I simulate effect of radiation on DNA at the nanometre level, to see how it causes strand breakages and oxidative damage. This requires the development of memory efficient DNA models with millions, ranging to billions, of base pairs.
Neutron stars are the compact remains of certain supernovae - the last great explosion from the most massive stars. The massive densities found in neutron stars allows for very extreme physics to take place on their surfaces.
I compared observations and simulations of thermonuclear x-ray bursts from neutron stars and built programs to automatically analyse gigabytes of simulated data.
The data is available to browse at the KEPLER Models Wiki.
X-ray bursts occur around accreting neutron stars like the one drawn here (photo credit: NASA).
Here's a growing list of open source and side projects I'm playing with or contributing to.
You're welcome to find me on GitHub.
There is a huge amount of data available to the public these days, and it can be used to explore a wide array of questions. Some ideas that have interested me and I've writted about are the ways people behaved on Twitter near the 2016 U.S.A. Federal Election.
I've also investigated how the Brexit referendum's voter demographic differed from that of the people that signed the petition for a second referendum.
Hello Uni is an online revision platform that leverages machine learning algorithms to help students understand their weaknesses and improve on them.
Working with colleagues, we developed algorithms that use the ensemble of student performance data we collected to provide industry-leading student feedback.
OpenCFU is designed to quickly and easily allow biologists to count colonies on Petrie dishes.
My research in biology involves counting colonies of two distinct colours on petrie dishes, so I wrote the contribution necessary to automatically recognise the dominant colours present in an image so that different coloured colonies are counted separately.
For more information, see my blog post on the subject.
Recently, I added tooltip support to the project, so that users can have interactive access to documentation.
