She completed her undergradu- ate degree in Psychology at the University of Crete before coming to the United States to begin her graduate studies at Rutgers University, in the laboratory of Maggie Shifrar. After receiving her Ph.D. in Psychology in 1998 she spent a year as a postdoctoral student with Ken Nakayama and Nancy Kanwisher. She then moved to Germany to join the laboratory of Nikos Logothetis at Max Planck Institute in Tubingen. In 2005 Zoë moved to the University of Birming- ham to assume her fi rst faculty position. While a graduate and then a postdoctoral student Zoë has been exception- ally productive, publishing over 30 papers in high quality journals. In her research she employs psychophysical and multimodal imaging methods (fMRI, EEG, MEG) to inves- tigate the neural substrates of coherent visual perception in the human brain. Statement From the VSS Young Investigator Award Committee “The Award Committee recognized Zoë’s many outstand- ing fMRI studies that characterized the neural loci of shape processing in the human cortex. Her development of an The Young Investigator Award will be presented at important, widely used fMRI technique, ‘event-related adap- the start of the Keynote Address on Sunday, May 13, tation’ was also commended.
