Mars Buttfield-Addison (née Geldard) is a Software Engineer and Data Scientist, currently working towards a PhD in Computer Engineering with the University of Tasmania and CSIRO Data61–investigating the use of machine learning to assist large-scale radio telescope installations in reliably tracking objects in orbit. Before that, she completed successive degrees in ICT in which she conducted research across domains as diverse as serious games, information behaviours, public health and complex social media analysis. But that wasn’t enough to channel her passion for technology: Mars is also a frequent volunteer and speaker at industry events worldwide; a teaching and research assistant at UTAS; a freelance developer and author of educational materials (including Practical AI with Swift for O’Reilly Media, and related books still in the works); a conference organiser (/dev/world and EveryWorld), industry council member (AUC and prev. ACS) and community advocate in the field of Swift and Apple platform development, just to name a few. She spends any remaining time she has helping to build the world of Game of Thrones in Minecraft as part of the WesterosCraft project, supporting whatever antics her game developer husband is up to, tweeting about Star Trek at @TheMartianLife, or in the wilderness.
