About myself

I work on dataflows, databases and Rust at Materialize.

I completed my PhD in Timothy Roscoe's group as part of the Systems Group at ETH Zurich. In my PhD, I created a tool to perform bottleneck analysis for distributed streaming dataflow applications, a policy to determine optimal parallelism levels and mechanism to apply dataflow reconfigurations with latency constraints.

I graduated from my PhD program in April, 2019. From June 2019 until May 2021, I worked at Google Zurich.

  • Strymon is a platform to run data center operations and monitoring. I am working on performance analysis of distributed dataflow applications and scaling mechanisms.
  • Barrelfish is a research operating system to explore multi- and many-core architectures using novel approaches from distributed systems. My research was in the field of scaling-out Barrelfish across many physical machines using low-latency interconnects.

Personal projects

  • columnar-rs is a Rust library to transparently convert row-based memory layouts into a columnar variant. This can yield a significant performance improvement due to better cache utilization and dense data.
