Bianca's research is in group theory, which is the mathematical study of symmetry. The particular question that she has studied arose from some work of a famous model theorist, Gregory Cherlin. He wanted to know what finite primitive permutation groups exhibit "large relational complexity". Bianca was able to answer this question in a very strong way -- her main result comes close to classifying those primitive permutation groups on a set of size t that have relational complexity greater than 22log(t). This was a better answer than had originally been hoped for -- Cherlin's initial question only concerned groups with relational complexity greater than t^(1/2).
