primary research is in the area of algebraic topology, specifically
questions involving localization and model categories. My work has
applications to the theory of algebras over (colored) operads,
homotopy theory, and motivic homotopy theory. In the near future I plan
to do more work developing
the theory of Bousfield localization, to better understand the various
model structures which arise in equivariant homotopy theory, and to
investigations into motivic homotopy theory. My PhD thesis was
supervised by Mark Hovey,
and my coauthors in homotopy theory have included Michael
Batanin, Donald Yau,
Javier Gutierrez, Gabriel Valenzuela, Boris Chorny, and
have also done research in computer science and discrete mathematics.
Under the supervision of Danny
Krizanc, my Master's thesis
settled a conjecture involving autonomous agents
moving on a graph. At Denison, I supervised an undergraduate research
project resulting in a paper (with Jessica Tang) about the structure of
I have begun to dabble in statistics, with two papers so far
focusing on statistical pedagogy. I have also supervised undergraduate
research projects in statistics related to spatial econometrics,
genomic modeling, and R package development.
I have done work in Economics, with my co-author Olga Nicoara,
to create a game theoretic model for the collective action problem in
revolutions, with a particular focus on the rebellion in Ukraine.
I am also an active contributor to MathOverflow.

an undergraduate I was lucky to be part of two REUs, so I firmly
in the value of research for undergraduates. I maintain a list
of projects on which I would be happy to collaborate with
undergraduates and early graduate students in mathematics or computer
science. If you're interested in seeing this list please email me.
To Denison students: I will happily take on research students in
applied statistics at any time, ideally during the semester. For pure
mathematics or computer science, my research interests tend towards the
abstract. Thus, research with me will likely best serve students
interested in graduate school. For such students, the best time to do
research with me is during the summer after your sophomore year, or as
an independent study in your junior or senior year. The summer after
your junior year would be best spent at an REU, to best position
yourself for applying to graduate school.
A nice collection of open problems about popular games can be gleaned from this MathOverflow question.
