Dillon studied mathematics at Victoria University of Wellington and Oxford University, and received his PhD in 2005. He works mainly in an area of mathematics called matroid theory. Matroids are abstract mathematical objects that can be though of as geometries with only a finite number of points.
He has been interested in mathematical outreach activities since 2007, when, in conjunction with Ian Smith of the Wellington Mathematics Association, he ran a series of sessions for high-school students from around the Wellington region. This series has now evolved into regular school visits. Topics discussed in recent years include knot theory, combinatorial games, and the law of large numbers.
Aside from mathematics, Dillon is interested in music. His first degree was in orchestral performance, and he still plays in Wellington orchestras from time to time.
