Jan S. Rellermeyer


I received my MSc CS in Distributed Systems from ETH Zürich, Switzerland, in 2006 and completed my PhD in Computer Science in the Systems Group at ETH in 2011. My thesis work was on Modularity as a Systems Design Principle.

In 2010, I did an internship at Microsoft Research in Redmond, WA in the eXtreme Computing Group and worked on an operating system design and energy management for the Intel SCC (Rock Creek) architecture.

After graduation, I joined IBM Research in Austin, TX where I worked as an RSM in the Future Systems and Next Generation Datacenters Group. I was part of the team that built and released the first mobile app that IBM ever published, IBM Mobile Systems Remote. This effort lead sparked the IBM Mobile First initiative. I was also a co-lead of the winning 2013 Global Technology Outlook (GTO) topic Software-Defined Environments. After mobile systems were turned into a product group in 2015, I remained in Research and moved to workload-optimized systems for the POWER architecture where I leveraged features like coherently-attached flash through CAPI. This work is available on Github, In 2016, I worked on cloud and datacenter computing and in 2017 my group was assigned to work on machine learning and natural language processing.

In 2013, I became an Adjunct Assistant Professor in the Department of Computer Science at The University of Texas at Austin and taught the Programming Languages, Programming Languages Honors, and Principles of Computer Systems classes until 2017.

In September 2017, I left IBM Research and joined the Distributed Systems Group at TU Delft as an Assistant Professor.

I was the Invited Researcher of the OSGi Alliance from 2008-2011 and contributed to several successful open source projects in the Eclipse and Apache Foundations. I am the project lead of the Eclipse Concierge project.

In 2015, I was a mentor for the Facebook Open Academy and worked with students from UNICAMP Brazil.

In 2017, my co-authors Gustavo Alonso, Timothy Roscoe, and I received the ACM/IFIP/USENIX Middleware Test of Time award for our 2007 paper R-OSGi: Distributed Applications through Software Modularization.



My research revolves around building and researching large-scale distributed systems for demanding applications like Big Data Processing and Distributed Machine Learning. I am interested in the architecture of systems and the resulting properties like performance, efficiency, scalability, reliability, and security.
