I'm Aaron Golden, a lecturer in the School of Mathematics, Statistics and Applied Mathematics, at the National University of Ireland, Galway. I also spend time doing research on what some people would regard as two completely different areas, namely Astronomy and Bioinformatics. What links them at a basic level is that both involve large, noisy datasets containing complex signals that you need to somehow decode in order to understand the underlying physics/biology involved. A recent new area of interest is in the analysis of Earth Observation datasets, particularly in the implementation of statistical models to 'tie in' what we observe from space, and what we can actually measure at the Earth's surface... My PhD was in astronomy - observing and analysing incredibly faint pulses of light from several nearby pulsars using a camera that was supposed to fly on the Hubble Space Telescope but failed quality control - and after I started working in NUI Galway I discovered that I could apply many of the same data analytics tricks from astronomy to other interesting problem domains. But I still like to go observing...!
