Lori Koban’s research is in combinatorics, especially matroids and their connections with graph theory. The main topic of her work is gain and biased graphs. These are graphs with additional structure that leads to new graphical matroids. The theories of gain and biased graphs are being developed by her advisor, Thomas Zaslavsky, in a series of papers entitled Biased Graphs.  She has developed interests in both actuarial education and mathematics education.
