Research


agu

I am currently an EU Marie Curie Postdoctoral Research Fellow at the Institute of Science and Technology Austria (ISTA). My research concerns the use of high-resolution and parameterised atmospheric simulations to study deep convection and climate change, i.e. the formation of clouds and they would change in a warming climate. I was previously a postdoctoral research at the Climate Change Research Centre at UNSW in Sydney, Australia.

I completed my Doctoral studies at the Australian Centre for Astrobiology (ACA) at the University of New South Wales, Australia. My research concerned gathering empirical evidence for the processes, impact and outcomes of social media science communication by means of computational techniques. The science topics that I focused on were space science and climate change related. Given the amount of time, money and effort spent on social media science communication, it striked me as odd and particularly curious that little concrete evidence has been provided in terms of the effectiveness of these activities. I was especially interested in the effects of social media engagement on public trust in science. Does online engagement with scientists improve public trust in science? How do we communicate science better on social media to build public trust? These were the questions I aimed to answer. My PhD Thesis can be downloaded from here.

I have a special interest in big data and the potential to glean meaningful insights from them to inform decision making. As I have a background in engineering and computer science, I decided to use machine learning to approach my research questions. The techniques that I have used include supervised and unsupervised learning, sentiment analysis and topic modelling. I wrote a blog post to explain my findings so far and linked to the source code for my experiments. Ultimately, I am interested in using the knowledge and results gained from my analysis to develop intuitive and useful tools to help scientists communicate their research to the public.

In a previous life I was a European Commission funded Marie Curie Fellow at the European Organisation for Nuclear Research (CERN), working as a data acquisition engineer for the Compact Muon Solenoid (CMS) experiment of the Large Hadron Collider (LHC) accelerator. The CMS collaboration is one of the two experiments that detected the Higgs Boson, a discovery that won its eponymous predictor Professor Peter Higgs a Nobel Prize in Physics in 2013.
