Diego Millan Berdasco


Postdoctoral Research Associate

Room Number: Mathematical Sciences Building, Room: MB-202


In October 2021, Diego started a postdoctoral position at QMUL (funded by EPSRC).

Diego completed his PhD student at Queen Mary University of London under the supervision of Dr. Matthew Fayers. The title of his research project is “Decomposition numbers for symmetric groups”, which lies in the interface of representation theory and algebraic combinatorics. In the course of this research, Diego visited Dr. Conchita Martinez at Universidad de Zaragoza to study homological techniques in representation theory.

Previously, Diego studied Mathematics at Universidad Complutense de Madrid (BSc, 2016), with a dissertation on Galois Theory titled “How to obtain the solution of the solvable quintics?”.  He also spent a semester studying at the University of Bristol under an Erasmus+ grant.



Diego is a Teaching Associate and a Demonstrator at the School of Mathematical Sciences across the BSc Mathematics syllabus. This involves a number of teaching related tasks such as running tutorials and support sessions, supporting academic staff and marking and assessing students work and exams.

Public Engagement


Diego has supervised the Royal Institution Mathematics Masterclass 2019 series. 

He has spoken at graduate events on behalf of QMUL at the University of Oxofrd (2017) and the University of Cambridge (2019).

He design content and tutored at the QMUL Mathematics Summer School 2017.

He was also a co-organiser of "Atoms to Galaxies" strand of the Pint of Science festival  2017.

In addition, he has delivered outreach talks for various audiences, including at the Further Mathematics Support Programme and QMUL Graduate festival.
