Jared León

I am a PhD student at the Centre for Doctoral Training in Mathematics at the University of Warwick. I am being supervised by Oleg Pikhurko. I obtained my MSc degree at the University of Sao Paulo under the supervision of Yoshiharu Kohayakawa.

I am interested in extremal and probabilistic combinatorics, graph theory, and the application of the flag algebras method to problems in combinatorics.

I like films... quite a lot.

I am a member of the Finite and Descriptive Combinatorics and DIMAP groups at Warwick, and a former member of the TCCO group at IME-USP.

What am I up to?

I am an organiser of the 30th Postgraduate Combinatorial Conference to take place at the University of Warwick during 15th-17th April. Registrations are open until 2nd of March.
