### Biography

Lleonard completed his BSc in Mathematics at Università di Roma La Sapienza in 2010. In 2008, during this degree, he took part in Percorso di Eccellenza (advanced courses). He obtained an MSc degree in Geometry and Algebra in the same university in 2013. Lleonard spent the second year of his Masters at Queen Mary University of London as part of the Erasmus programme.

Lleonard is currently working on his PhD at City with Professor Markus Linckelmann.

### Research Interests

Modular representation theory of finite dimensional algebras from a cohomological point of view.

Lleonard is interested in the interplay between the algebra structure and the cohomology. He is currently working on the compatibility in the Hochschild Cohomology between the p-power map of the restricted Lie algebra structure and the transfer maps induced under stable equivalences of Morita type. In addition, in degree one he is looking at connections with integrable derivations.
