Research areas
My main research area is computability theory. In this field, we look at the theoretical power of computers if there were no limits on the memory and running time of programs. In my subfield, Reverse Mathematics, we apply computability to study mathematics itself. We can separate mathematical theorems into different levels of strength depending on how much noncomputability the theorems require. I have also published papers in other areas, including combinatorics and general topology.
I regularly supervise student projects in mathematics and computer science. I have co-authored three peer-reviewed papers with undergraduates to date.
I am also interested in educational research in Inquiry Based Learning, and in Digital Humanities.
