Selected Publications
My primary research has been in Topology, Real Analysis, and Measure Theory, and involves classifying sets in topology and analysis (part of an area known as Descriptive Set Theory). Recently, I have also been interested in Randomness in Sequences and Non-standard Analysis.

Expository Articles
Topology Atlas was founded by Dmitri Shakhmatov and Stephen Watson in 1995 as a comprehensive online resource for topology. It seems to have gone offline permanently in 2020 (partial content may be available via archives at Wayback Machine). The following appeared in Topology Atlas in 2005.
