I am a Senior Member of Technical Staff at Oracle Labs Zurich in the MLE team.

I did my Ph.D. in the ERODS team at the Laboratoire d’Informatique de Grenoble. My advisors were Dr. Renaud Lachaize and Prof. Vivien Quéma. From June to September 2017, I was an intern at Oracle Labs Zurich, inside the Walnut team, working on leveraging the Graal compiler within the Oracle database and existing big data technologies. I received my Bachelor degree in 2013 and my Master degree in 2015 from the University Joseph Fourier.


My primary research interests are in Operating Systems and Multicore Architectures, Application Virtual Machine, Databases and Compiler technologies.
