Kathryn Jane Jeffery is a neuroscientist from New Zealand. She is a professor of behavioural neuroscience at University College London. She studies how the brain encodes three-dimensional space and its role in navigation.
Jeffery graduated with a degree of MB ChB from the University of Otago in 1985. After working as a house officer, she returned to the University of Otago to complete a master's degree in 1989 under the supervision of Cliff Abraham. She completed her PhD at the University of Edinburgh in 1993 under the supervision of Richard Morris. During this time she worked in the same lab as May-Britt Moser and Edvard Moser. She went on to work as a postdoctoral researcher with John O'Keefe, who won the 2014 Nobel Prize for his work on place cells, at University College London. Jeffery correctly predicted he would win the Nobel Prize in a tweet.
Jeffery stayed at University College London to become a lecturer and later a professor. Here, she founded the Institute of Behavioural Neuroscience, of which she is also director.
