Research
The secret to doing good research is to always be a little underemployed. You waste years by not being able to waste hours - Amos Tversky
(If you have time for only one paper, look at Two Lives.)

Two lives: Compositions of Unimodular rows, Advances in Mathematics 389 (2021), 107917. [arXiv]
When multiple research areas evolve around the same object, one expects that there is a connection between them. The more distinct the methods are, the more fruitful this connection will be. In this paper, we will explore this double life for unimodular rows.
