My area of interest is logic, specifically computability theory. I did my PhD at the University of Wisconsin–Madison under the supervision of Joseph S. Miller.
Bjørn Kjos-Hanssen is my mentor at the University of Hawai'i.

Joseph Miller and I have created an interactive web-based version of his "Computability Menagerie". It depicts relationships between downward closed classes of Turing degrees, and is inspired by Bjørn Kjos-Hanssen's original version, which can be found here.
The Menagerie generates its graph based on a database file that contains some key facts about the classes. It can make a few basic types of deductions from these facts and fill in missing information.
You can tell the Menagerie to display only the classes that you care about. For example, this is a part of the diagram showing some questions that might be open.
The code is available here.
