After a master's degree at Imperial College London, she returned to University College London to gain a doctorate with a thesis titled "Dwarf Elephants on Mediterranean Islands: A Natural Experiment in Parallel Evolution".
Her research addressed evolution of island mammals during the Pleistocene period and their responses to extreme climate change.
[3] Herridge delivered the 2012 Charles Lyell Award lecture at the British Science Festival[4] and co-wrote Who Do You Think You Really Are?
As well as her academic output she is a popular science writer: her work includes a piece on the ethics of cloning mammoths versus the importance of saving endangered elephants, and one on the importance of studying the history of women in science (with Brenna Hassett, Suzanne Pilaar Birch and Becky Wragg Sykes), both published in The Guardian.
