I am part of the @Large Research group at
Vrije Universiteit Amsterdam and a member of the international
SPECRG Cloud research group.
I work on massivizing computer systems—making distributed infrastructure scalable, reliable, and performant—with
a focus on datacenter simulation, multi- and meta-model analysis, and digital twinning.
