# Jere Koskela

I'm a postdoc with Jochen Blath at the Technische Universität Berlin, working on applications and inference of multiple merger coalescents in population genetics.

I finished my PhD in 2016 under the supervision of Dario Spanò and Paul Jenkins. My thesis is Consistency and intractable likelihood for jump diffusions and generalised coalescent processes.
