My name is Kevin O'Neill. In 2019, I received my Ph.D. in mathematics from UC Berkeley under the direction of Michael Christ and I am currently a Krener Assistant Professor working with Kevin Luli at UC Davis. In Fall 2021, I will be starting a Gibbs Assistant Professorship in the applied math program at Yale.

My current research interests are in Whitney-type problems: smooth interpolation, smooth extension, and related algorithms. In particular, I am interested in connections with data science.

I am also interested in harmonic analysis, in particular problems related to extremizers and stability theorems.

For more information, see the "Research" tab of my page.

In my free time, I like to read books, watch basketball, and train for marathons.

Current Information (last updated September 20, 2022)

I am currently teaching MATH 480, Senior Seminar: Mathematical topics. Office hours are by appointment.
