Dr. Chook received an AB degree in Chemistry and Biology (major at Haverford College) from Bryn Mawr College in 1988. She received a PhD in Biophysics in 1994 from Harvard University, where she studied the structures and mechanism of chorismate mutase with William Lipscomb. Her postdoctoral work was with Emil Pai and Tony Pawson in Toronto studying signal transduction in the Ras pathway, and with Günter Blobel at the Rockefeller University studying the mechanisms of nuclear import.
In December of 2001, Dr Chook joined the Department of Pharmacology at UT Southwestern as an Assistant Professor and Eugene McDermott Scholar in Biomedical Research. The Chook laboratory aims to understand mechanisms of nucleocytoplasmic transport and molecular recognition by the Karyopherin-β nuclear transport receptors (Kaps; Importins and Exportins), classify nuclear traffic, and discover how Kapβs organize and regulate cellular functions. They seek to discover these roles of Kaps through a combination of structural, biochemical, biophysical, bioinformatics and cell biological investigations focused on Kap-cargo interactions.
