profile picture

I am a distributed systems researcher and software engineer. I was affiliated with Inria / UPMC until March 2015. Now, I am a software engineer at Google Zürich.

Research interests

My research interests evolve around distributed systems and database replication, in particular highly available systems with weak consistency models. In my PhD thesis, I demonstrated how to minimize the metadata cost of eventually-consistent replication systems based on (Conflict-free) Replicated Data Types (CRDTs) and on causal consistency. More generally, I am interested in maximimzing consistency guarantees, programmability and efficiency / scalability of eventually-consistent systems, as well as in understanding the limits and trade-offs of their design space.


I did my PhD between 2010 and 2015 at Regal, a joint research group of Inria and University Pierre and Marie Curie (UPMC, Paris 6), where I worked under the supervision of Marc Shapiro. My scholarship was funded by Google Europe Fellowship in Distributed Computing and Google Research Award. During that time, I interned with the cluster management team at Google Zürich in 2011 and with RiSE group at Microsoft Research Redmond in 2013.

I received my Bachelor's degree (2008) and Master's degree (2010) from Poznań University of Technology in Poland. I participated in the Google Summer of Code program for JGit project in 2008 and did two internships at Inria with Regal (2010) and Oasis groups (2010).

Personal (Marek in the wild)

I have always been passionate about offshore and ocean sailing. On the active side, I am at sea with my friends or family as much as I can (which always feels too little!). I keep track of approximate routes of my trips. Back at home, I enjoy following round-the-world races such as Volvo Ocean Race and Vendée Globe. I am also keen of mountain biking.
