Alan Hájek studied statistics and mathematics at the University of Melbourne (B.Sc. (Hons). 1982), where he won the Dwight Prize in Statistics. He took an M.A. in philosophy at the University of Western Ontario (1986) and a Ph.D. in philosophy at Princeton University (1993), winning the Porter Ogden Jacobus fellowship. He has taught at the University of Melbourne (1990) and at Caltech (1992-2004), where he received the Associated Students of California Institute of Technology Teaching Award (2004).

Hájek joined the Philosophy Program at RSSS, ANU, as Professor of Philosophy in February 2005.

Hájek's research interests include the philosophical foundations of probability and decision theory, epistemology, the philosophy of science, metaphysics, and the philosophy of religion. His paper "What Conditional Probability Could Not Be" won the 2004 American Philosophical Association Article Prize for "the best article published in the previous two years" by a "younger scholar".  The Philosopher's Annual selected his "Waging War on Pascal's Wager" as one of the ten best articles in philosophy in 2003.
