I am a computer scientist by trade.
I research, develop, and teach:
Sustainable & Dependable Systems
Also, I was born at 356ppm and generally care about sustainability.
I do research concerned with the following topics:
(you find a full list of publications below)
As of today, most computing systems lack first-class support for non-functional aspects (such as latency demand, energy demand, and also carbon emissions, ...). This includes both measuring, optimizing, and enforcing (at runtime) as well as arguing about the overall system integration (at design/compile time). Our work aims at bringing sustainability-awareness to computation and communication stacks—ideally reducing their environmental footprint.
The fourth industrial revolution (I4.0) puts computation at the heart of production systems. These industries have high requirements with respect to (worker) safety assurance and (product) quality assurance. In practice, this often involves various informal, non-generalizable, paper-based processes arguing about safety/quality. Our work is concerned with making these assurance activities more formal, more generalizable (i.e. modular, composable), as well as truly digital.
The hype around artificial intelligence approaches aside, there is potential in applying it (especially machine learning) in carefully chosen scenarios. In our work, we apply machine learning to problems involving dependable systems and networking, where traditional approaches failed (either due to computational complexity or lack of formal models). We do so in a informed manner, i.e. we refrain from building black-boxes and ignoring domain knowledge. Instead, we attempt to build hybrid solutions, using domain-knowledge where possible and only resorting to machine learning where appropriate.
