My research is in pure mathematics, though some of the motivation for the problems I work on comes from theoretical physics. I work in algebraic geometry, mainly on classification problems, studying geometric objects called moduli spaces.
While combining an academic career with bringing up three children, I have been very lucky to have had extremely supportive colleagues (as well, of course, as husband, family and other childcare support). In addition, being a mathematician may well have helped: for my research I have no need of a lab, and relatively little need of a library. Thus, in principle at least, I could do research while feeding a baby or singing lullabies to a toddler (though I am not sure that much of that happened in practice)!
