I received my B.A. from Reed College in 1989, and my Ph. D. from University of California at Berkeley in 1995. Before coming to Seattle University in 2007, I taught at Haverford, Lewis & Clark, and Smith Colleges. My research interests are in algebraic number theory, particularly on power bases and class numbers for cyclotomic fields. Recently, I have also become deeply involved in math outreach in the local public schools, and was awarded the Sister Kathleen Sullivan Endowed Professorship to support this work. I used funds from the endowment to start the Seattle University Math Corps (SUM Corps), which is a group of enthusiastic math students who lead a variety of outreach activities at Bailey-Gatzert Elementary and Washington Middle Schools.
