| Research | |
|
I am a researcher at National ICT Australia in the Managing Complexity research theme. My research interest is formal verification, in particular model checking and static analysis, and the application of formal methods in design and development of embedded systems. I am currently working on the Goanna, a tool for C/C++ that combines static analysis with model checking. This tools is the result of a NICTA research project also called Goanna. I previously also worked on the Pewna project that explored the use of formal method techniques, such as probabilistic model checking, for perfomance evaluation of wireless network applications. |

| Teaching | ||
| Together with Ralf Huuck I offer since 2006 the course COMP3153 - Algorithmic Verification at UNSW. | ||
| Benchmarks | ||
| Together with Franjo Ivančić I compiled a number of benchmarks for hybrid systems verification. The the instances and models can be found here. | ||

| A short CV | Miscellaneous | ||
| I was born 1971 in Teglingen, No 25. | My office mate in Nijmegen was Mariëlle | ||
| Later, I went for four years to the primary school in Teglingen, and ... | There is a link to my page on Mariekes homepage . | ||
| ... spent 9 years on the secondary school Gymnasium Marianum in Meppen. | I used to live in the ORKZ, first on station A2midden, later on station A2rechts. This is where I met Melanie. | ||
| I then left Teglingen to study Mathematics at the Philipps-Universität Marburg for two years ... | In 1998 I made some predictions for our soccer pool with reasonable results. | ||
| ... and continued studying Mathematics at the Rijksuniversiteit Groningen for four years. | In the summer of 1999 I moved to Ravenstein, together with Melanie and our two cats (called Mies and Mowie). | ||
| I spent about 4 years in Nijmegen to work on my PhD. | I lived in the Walnut Palace for one year. When Melanie came with the cats we moved to an apartment 2 blocks further on Walnut St. | ||
| From 2001 to 2004 I was a PostDoc at Carnegie Mellon University. | Melanie and I married in 2003 in Sandfirden. | ||
| From 2004 on I work at NICTA. From 2009 involved with the Red Lizards. | We (Melanie, Mowie, Mies and me) moved to Sydney . | ||
