Dr JM Field (Spearim) is a Gamilaraay mari from Moree way, but grew up on Darug land in a small town along the Great Dividing Range. He studied maths and French literature at the University of Sydney, before completing a doctorate at Balliol College, Oxford. He remains a research mathematician, with a focus on the mathematics and genetics of traditional kinship systems. His latest book, The Eagle & the Crow, explores the philosophical and practical complexities of Gamilaraay kinship through a series of lyric essays.
