Dr Hedgehog has engaged in multifaceted research on hedgehogs since 2011. Sophie is managing “The Danish Hedgehog Project”, a citizen science project, where volunteers collected 697 dead hedgehogs with the purpose of using the dead hedgehogs to understand the living. She has previously investigated the ecology of suburban hedgehogs, genetics, dental health, stress, personality, behaviour and survival of rehabilitated and wild juvenile hedgehogs, endoparasites, age, eco-toxicology, MRSA/ringworm in hedgehogs. She is currently leading projects on coronavirus, the microbiomes, diet choice, and the effects of robotic lawn mowers on hedgehogs to understand why hedgehogs are declining and how to stop it.
