Carolina Vallejo Rodríguez

I am a Severo Ochoa postdoctoral researcher at the ICMAT. I am part of the research team of Andrei Jaikin. My main interest are the so-called counting conjectures, which fit into the class of global/local problems in Group Representation Theory.

Previously, I was an MSRI postdoc associated with the program Group Representation Theory and Applications at the UC Berkeley.

I completed my Ph.D. (as well as my Degree and Master) at the University of Valencia. I worked under the supervision of Gabriel Navarro. The main goal of my Ph.D. thesis was to find explicit bijections between character sets, so that fields of values of characters were preserved.

The UAM/ICMAT group theory seminar is organized by Yago Antolín, so you can contact him if you are willing to give a talk. Here you can find a list of talks for the current academic year. I co-organised the third edition of "Groups in Madrid" last year.


I co-organise the workshop "Counting conjectures" within the scientific programme "Groups, representations and applications: new perspectives" to be held at the Isaacs Newton Institute for Mathematical Science (Spring semester 2020).

Some beamer talks

I have only used beamer in my first three talks. I don't really like giving beamer talks (mainly because I'm not good at it). You can find the slides below.


My PhD. thesis has received a Vicent Caselles Award 2018 edition (a video made for this edition can be found here) and a special mention in the Reinhold Baer Prize 2017 edition (whose winner was Urban Jezernik).

The Vicent Caselles awards are given by the Royal Spanish Mathematical Society and the BBVA Foundation and their aim is to «celebrate knowledge through Mathematics».
The Baer Prize is given by the association AGTA that aims to «promote and disseminate the scientific culture and the research in group theory and its applications».

I visited the Institut Jussieu in June 2018.

Sunset view from the outside of the Hôtel Lauzun in Paris.

I visited the TU Kaiserslautern during July 2017.

Wild raspberries in the Palatinate forest.

I visited twice the TU Kaiserslautern while completing my PhD studies.

The forest is especially beautiful in autumn.
