Who am I?
Since 2013, I am working at Oracle Labs on the
I am doing systems research and I like to actually build stuff.
I am also teaching at ETH, right now the lecture
Programmieren und Problemlösen.
I did a PhD in Computer Science in the
Computer Science Department
of ETH Zürich
from 2007 to 2012 with Prof. Dr.
My PhD thesis is about "Tackling OS Complexity with Declarative Techniques".
Before joining the group, I studied computer science at
ETH Zürich and got my Diploma/MSc
My main research interests include operating systems design, applying
constraint logic programming techniques to hardware programming and
resource management on multicore machines as well as finding an ideal interface
between manycore operating systems and managed language runtimes such as Java
to let (legacy) applications better use the underlying hardware.

I'm currently working on Barrelfish,
a new operating system for heterogeneous many-core machines written from
scratch. As part of this, I'm building a system knowledge base (SKB)
which contains detailed system and hardware information as declarative
The SKB is used to gather detailed hardware information as well as
runtime information about the system and running applications.
Based on this information, declarative algorithms and queries
derive valid hardware configurations as well as intelligent resource
allocation policies. Being a central user-space service in Barrelfish,
it has global knowledge about the complete state of the system. The
system and applications can query the SKB at any time and run their own
declarative algorithms based on the stored data.
Alpenrhein is a joint project with Michael Duller. We explore how an
interface between the OS and the managed runtime system should look
in terms of information flow in both direction to improve
hardware resource utilization.
By extending the interface between the runtime system and the OS,
legacy application written on top of the runtime system can
benefit from modern manycore systems without modification.
Semantic information about the application within the runtime system
provides deeper insight into a new or legacy application and allows
to automatically derive resource needs in terms of memory, caches, cores
and interconnect. Communication, synchronization, computation and
memory allocation information is provided to the SKB which then
gets a global view and can provide feedback to all running instances
in the system.
We are currently basing our research on the
a research Java Virtual machine developed at Oracle Labs and
the Barrelfish OS.
Rhizoma is a self-managing overlay which deploys an application to a
number of nodes in the internet or on a cluster
based on application requirements. Additionally, Rhizoma manages itself
by moving itself to nodes which have the
necessary resources to run a controller.
In collaboration with Qin Yin,
we implemented a prototype with algorithms
implemented in Eclipse-CLP to derive the necessary resource allocation

I like teaching a lot and regularly have the opportunity to prepare
teaching material as well as standing in front of exercise classes and
teach the material. Sometimes I had the opportunity to be a head
assistant and organize the exercise sessions.
