Deirdre Haskell, Deputy Director, was born in Philadelphia, PA, USA in 1963. She moved to England in 1974, where she went to school and university, completing her BA at Oxford University in 1984. She moved back across the Atlantic to pursue a PhD at Stanford University, awarded in 1990, and back once more for a postdoctoral fellowship at Queen Mary College of the University of London.  A final transatlantic move took her to the College of the Holy Cross in her first tenure-track position. Another country then beckoned, and she moved to McMaster University in Canada in 2000, where she was promoted to full professor and served several terms as associate chair (undergraduate) of the Mathematics and Statistics department. Dr Haskell’s research in model-theoretic algebra has been supported by grants from the NSF and NSERC. During her career, she has organised many international conferences, including some at the Fields Institute. She has served on committees of the Association for Symbolic Logic, on the editorial board of the Bulletin of Symbolic Logic, and is currently a managing editor of Math Logic Quarterly. When not doing mathematics, she enjoys skiing, sailing, and hiking in the Sierra Nevada mountains in California.
