I have studied Computer Science at the Vienna
University of Technology and received the Master degree in 1995.
In January 2001, I started Doctoral Studies in Technical Sciences at the
Vienna University of Technology, Prof. Hermann Kopetz being my research
advisor. I finished my studies and received the PhD degree (Dr.techn.) in
October 2004. From 2003 to 2006, I have been a research assistant and a
member of the Real-Time Systems Group at the Institute for
Computer Engineering,
Vienna University of Technology, Vienna, Austria.
In November 2009, I started a post-graduate study in Business Administration at
PEF Private University of Management in Vienna. I finished my studies in November 2011.

Research
My research focus is on fault-tolerant clock synchronization in
distributed real-time systems and simulation. My current activities
are
- Clock synchronization strategies
for multi-cluster real-time systems
In the course of my PhD Thesis, I investigated clock synchronization algorithms and developed strategies for multi-cluster clock synchronization. These strategies have been developed by means of simulation and have been validated for single-cluster systems by means of hardware experiments with TTP/C clusters.
- SIDERA, a simulation system for
time-triggered distributed systems
SIDERA (SImulation model for DEpendable Realtime Architectures) is a software tool intended for the simulation of distributed real-time architectures in a single computer system. We have used SIDERA for the development of a clock synchronization algorithm that combines fault-tolerant clock state correction and central clock rate correction as well as for the investigation of multi-cluster startup scenarios. SIDERA is also capable of simulation of the clock synchronization algorithm used in the Flexray protocol. The work on and maintenance of SIDERA was closed in Summer 2009 due to lack of time for further development :-( However, the final release of SIDERA including different configurations for single-cluster systems and multi-cluster systems can be ordered here.My research activities have been supported by the Austrian Science Fund FWF, contract number P16638, "Uhrensynchronisationsstrategien". The project was finished in January 2007.
Professional Life
Although scientific research is my passion, I have some other
things to do to bring money home.
After my graduation in Computer Science in June 1995, I started my professional career as a software engineer in the
field of voice communication systems for air traffic control at Frequentis Nachrichtentechnik AG.
From November 1998 to June 2009, I have been under contract at SIEMENS Austria, where I was concerned with the design and
implementation of software and firmware for embedded systems for telecommunication and process control applications.
In the course of my last project I was working in a safety relevant automotive project that dealt with
the development of a driving dynamics control unit based on a FlexRay bus communication system.
When I left Siemens in June 2009, I started to review my career opportunities. Always having been interested in economics,
I decided to take a time out and to learn something new. In November 2009, I started a post-graduate Master of Business Administration
study at PEF Private University of Management in Vienna that I finished in November 2011.
From October 2010 to December 2014, I was under contract at the AIT Austrian Institute of Technology, department Safety & Security. My main activities there were related to design and validation of network architectures for the next generation of electric cars.
From January 2015 to December 2016, I was working for Siemens Corporate Technology, where I am concerned with software engineering and research,
related to control systems for distributed smart power grid applications.
Since January 2017, I am working at sIT Solutions AT Spardat Gmbh. I have returned to my roots, doing ,software development for bank applications and tools in a Scrum team.
Besides my development activities, I am responsible for operation and maintenance of different bank services. Due to the high availability requirements of bank services, this is a very interesting and
challenging task.
