Hi and welcome to my home page. I am currently working as a visiting researcher at Google working on scheduling and resource management in Google Cloud. I am on leave from my faculty job - I'm an associate 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 the Faculty of Electronics and Information Technology, Warsaw University of Technology, Poland.

I'm co-chairing Euro-Par 2020 in Warsaw, Poland. Hope to see you in August!

My CV

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

I'm looking for a post-doc (a 12-months fixed-term job contract extendible by 9 months funded by the Polish National Science Center). Contact me for details; apply by 10th July!

opal: optimization methods for of large-scale computational resources, a project founded by the Polish National Science Center (a 3-year Opus grant, October 2018-August 2021).

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

Recent TPCs: IPDPS 2019; Supercomputing 2019; Euro-Par 2018 (scheduling track co-chair); AAAI 2018; BeyondMR 2018; IJCAI 2017; ICPP 2017; SPC 2017.
