Simon graduated with a BA (Hons) in physcial geography and a PhD in palaeoecology and archaeology from the University of Melbourne in 2007. He subsequently undertook post-doctoral research at the University of the Algarve (Portugal, 2008-2012), was a lecturer in physical geography at Monash University (Australia, 2013-2014) and the University of Melbourne (2015-2016), and invited researcher at the Université Bourgogne Franche-Comté (France, 2018-2019). He joined the ANU in 2019.

Simon's research includes studies of air pollution history in Sydney, interactions between prehistoric cultures and vegetation in the Caucasus region, climatic change in the Balkans, forest disappearance along the Portuguese coastline, fire history in Mediterranean mountains, the creation of cultural landscapes in Tasmania's World Heritage Area, human impacts on island ecosystems, interactions between past fire and biodiversity change on the Iberian Peninsula, and early European impacts on the 'intact' savannas of NW Australia.
