Barbara Sattler (ancient philosophy), currently Assistant Professor of Philosophy at Yale University, has accepted a (permanent) appointment as Lecturer in Philosophy at the University of St. Andrews.  This is the second loss in ancient philosophy for Yale in roughly the last year (the other being Bobzien's departure for Oxford).  Verity Harte, a leading senior scholar in the field, remains at Yale, and I would imagine the Department will make other appointments in the area before long.
