Dallas Albritton
About Me
I am an Assistant Professor at the University of Wisconsin-Madison. My research interests are in pure and applied aspects of partial differential equations and fluid dynamics.
In 2022-23, I was an NSF Postdoctoral Fellow at Princeton University, where my sponsor was Peter Constantin. In 2021-22, I was a Member of the Institute for Advanced Study, where my mentor was Camillo De Lellis. In 2020-21, I was an NSF Postdoctoral Fellow at the Courant Institute at NYU, where my sponsor was Vlad Vicol. In 2020, I completed my PhD in Mathematics at the University of Minnesota under the supervision of Vladimír Šverák.
I am partially supported by an NSF Standard Grant.

Lecture notes
Lecture notes on instability and non-uniqueness in the Navier-Stokes equations. From my 4 hour minicourse at the UMN Summer Workshop on Analysis of PDEs. [Dropbox]

Thesis
Regularity aspects of the Navier-Stokes equations in critical spaces, 2020. [pdf]
Content not published elsewhere: Chapter 2 contains a summary of the Navier-Stokes theory which is suitable for newcomers to the field. Chapter 3 contains a streamlined version of my 1st paper (Anal. PDE, 2018), though this version was not peer reviewed, and it is anyway superseded by my 1st paper with Barker (ARMA, 2019).
Press
This work with E. Brué and M. Colombo was featured in Quanta, the Research Highlights of the NSF Mathematical Sciences Institutes, and in a Korean popular science magazine aimed at young people.
