Machin graduated with a B.A. in anthropology and English, followed in 1999 by an MSc in human evolution and behaviour from University College, London. In 2006, she obtained her PhD in archeology from the University of Reading.

After getting her PhD, Machin was a postdoctoral fellow working with Robin Dunbar from 2008 to 2014, after which she became a visiting academic while also pursuing a career as a freelance scientific writer and broadcaster.^[1][2][3]

Within archeology, Machin has studied and commented on the symmetry, morphology, effectiveness, and sex appeal of Acheulean handaxes.^[4][5][6]

Machin has done research on attachment and love between parents and children, between loving couples, and between best friends.^[7][8]

As an evolutionary anthropologist, Machin believes that both mothers and fathers have been primed by evolution to parent their children. She has studied father-child relationships and takes the position that human fatherhood would not have developed unless the investment that fathers make in their children is vital for the survival of the species. She has concluded that fatherhood was fundamental to the development of humans and humanity, with fathers performing critical parenting tasks in coaching and educating their children.^[9][10]

Machin has also studied the expectations and reality of fatherhood, and systemic impediments to fathers' involvement in their children's lives.^[11]

Machin has been interviewed and cited about fatherhood and love relationships by a variety of popular media outlets, including New Scientist,^[12] The Guardian,^[13] the BBC,^[14] The Daily Telegraph,^[15] Daily Mirror,^[16] Eltern,^[17] and Broadly.^[18]
