My name is Josué Tonelli-Cueto. However, this is a small lie. My actual name is Josué Tonelli Cueto. In Spain, it is customary to have two surnames, one being the first one of the father and the other one the first one of the mother. However, to avoid confusion in international contexts, I write my surname with a dash. In this way, it is clear that both words form part of my surname and that none of them is a middle name.

I am originally from Bilbao, a city of the Basque Country in the north of Spain, although I was born in Santander, another city in the north of Spain. I consider myself from Bilbao because that's the city I grew up in and I was brought up in. Also, as they say in Spanish, “the cow is from where it grazes” and “people from Bilbao are born wherever they want.”

Currently, I am a PhD student of Peter Bürgisser and Felipe Cucker at the Technische Universität Berlin. My interests are numerical algorithms and condition-based complexity, computational algebraic geometry, and random geometry. Luckily, I spend parts of the year traveling around the world either going to conferences, visiting colleagues or visiting Felipe at the CityU Hong Kong. Right now, I am writing my PhD thesis, which I will defend on the 28th of November of 2019.

Apart from discussing, thinking and writing about mathematics, I also enjoy other aspects of life. Here is a quasi-random alphabetical list of another ten things I enjoy: 1st, chatting and discussing random topics with friends (and sometimes other people) over a beer (or other equivalent drink); 2nd, drinking coffee; 3rd, folding origami figures; 4th, Iberian ham; 5th, reading non-mathematical books; 6th, riding a bike; 7th, sending postcards; 8th, swimming in the sea (when possible); 9th, walking while lost in my thoughts; and 10th, writing short stories, poems and calligrams. Of course, there are more things I enjoy, like cats, but listing things I enjoy is not something I enjoy.

I studied the Licenciatura en Matemáticas, which is a five-year bachelor in mathematics, at the University of the Basque Country between 2009 and 2014. During my studies, I founded and edited, together with Ricardo Grande and the help of Marta Macho-Stadler, the magazine $\pi kasle$. This magazine was a magazine about popular mathematics written by students. Also, I participated in the debating club of the university.
