Biographical Review

I was born in 1986 in Madrid, Spain. I studied Mathematics at Universidad Autónoma de Madrid (Licenciatura en Matemáticas por la UAM) and spent one year in Bergen, Norway, to study at Universitetet i Bergen with the Erasmus Student Exchange Programme.

In 2010 I obtained a Master's Degree in Mathematics and Applications from Universidad Autónoma de Madrid. My Master's Thesis, which was supervised by Adolfo Quirós, was centered on Mordell-Weil's Theorem and the theoretical difficulties to compute the rank of an elliptic curve.

I obtained my Doctoral Degree at Mathematics Depatment from Universidad Autónoma de Madrid in January 2015 and was funded by the Spanish Ministry of Education as a member of the Training University Lecturers Programme (FPU). My thesis was entitled: Congruence problems and questions regarding sequences of numbers, and supervised by Professor Javier Cilleruelo.

 

Research Interest

Additive and combinatorial number theory.

Concentration and distrubution of solutions to equations in congruences. Arithmetical structures in random sets.
