I grew up in Morelia, Mexico. I graduated in Philosophy from the Autonomous University of the State of Mexico and I obtained a PhD in Logic and Philosophy of Science from the University of Salamanca, under the supervision of José Ferreirós and María Manzano. During my PhD, in 2014, I was part of the CD Armuña team that won second place in the Spanish Marathon Championships.

My research focuses on the transition from mathematical practices that were common in the 18th century to practices that emerged in the second half of the 19th century, as well as on the work of Bernard Bolzano. I am also interested in the changes in mathematical education and the circulation of knowledge during this period. My work integrates features of textual studies and the philosophy and history of mathematical practices.

In 2018 I was awarded the Josef Dobrovský Fellowship by the Akademie věd České republiky (AV ČR). After that, I carried out a two-year postdoctoral stay at the Department of Mathematics of the Faculty of Sciences at UNAM and since 2020 I have held a postdoctoral position at the Filosofický ústav AV ČR with a project on Bolzano and the philosophical and mathematical problems of the continuum. From January 2023 I will be the principal investigator of the Junior Star project “Normalisation and Emergence: Rethinking the Dynamics of Mathematics. The case of Prague in the First Half of the 19th Century”, funded by the Czech Science Foundation.

Together with Steve Russ, I am responsible for the website **B**olzano in Prague. I am also responsible for the itinerant Seminar on the Philosophy of Mathematics.
