Hi and welcome to my home page. I'm working as an assistant professor in the Institute of Informatics of the Faculty of Mathematics, Informatics and Mechanics, University of Warsaw, Poland, where I did my habilitation (HDR) in 2015.

Before joining UW, I was working as a research fellow (post-doc) in Anwitaman Datta's SANDS working group in the School of Computer Engineering (SCE) of the Nanyang Technological University (NTU), Singapore. I did my PhD on resource management in grids jointly in Laboratoire d'Informatique de Grenoble of Institut national polytechnique de Grenoble, France and Polish-Japanese Institute of Information Technology, Warsaw, Poland, as a French government fellow (co-tutelle grant). I graduated with a MSc from Warsaw University of Technology, Poland.


I'm interested in resource management and scheduling in large-scale distributed systems, such as clouds, datacenters or fogs.

OStrich a cool scheduling algorithm for bag-of-task applications (with SLURM implementation!).

kassate: resource management in datacenters, a project founded by the Polish National Science Center (a 4-year Sonata grant, July 2013-December 2017).

NebuloStore, a prototype distributed storage system, founded by the Foundation for Polish Science (a Homing Plus grant, May 2011 - July 2013).
