Nuno Arala Santos

I am a fourth-year PhD student under the supervision of Dr. Simon Rydin Myerson and Dr. Sam Chow. In Fall 2024 I will join Leibniz Universit├Ąt Hannover as a postdoc in the research group of Prof. Dr. Ulrich Derenthal.

E-mail address: Nuno.Arala-Santos(at)


Number Theory, especially interactions between Analytic Number Theory and Diophantine Geometry.


I obtained my Bachelor's degree from the University of Porto in 2018. I then did my Master's at the University of Bonn, which I finished in 2020. I wrote my Master's Thesis under the supervision of Valentin Blomer, who introduced me to the delta method.

For more information on my background see my CV.

Miscellaneous writing

Below are some math-related texts I wrote over the years, for various purposes. Unfortunately, some of them are written in Portuguese.
