Marshall Sherfield Fellow Karen studies the behavior of animals in their natural environment through fieldwork and the use of genetic information. She has studied the behavior of wildlife in many countries throughout the world, mostly in Africa and the tropics. As a Marshall Sherfield Fellow, Karen will investigate the cues used by wild mice to choose their mates. She will carry out this research in the Department of Zoology at Cambridge University as a member of both the Large Animal Research Group and the Molecular Ecology Group. Karen holds a BS in Environmental Engineering Science from the Massachusetts Institute of Technology and a PhD in Integrative Biology from the University of California at Berkeley. Karen's favourite past-time is horse riding and, although she generally rides Western style, looks forward to improving her English riding skills while in the UK.
