I’m a software engineer in the Cloud and Computing Infrastructure Department at the IBM Research Zurich Lab. My research interests are in virtualized distributed systems and data centers, specifically in state-of-the-art network technologies.

I earned my Bachelor and Master degrees in Computer Science at the Swiss Federal Institute of Technology (ETH) in Zurich in 2014.

Currently, I’m working on the Crail project which tries to exploit high-performance I/O devices with a focus on Remote Direct Memory Access (RDMA) and non-volatile memory (NVM) in data-processing frameworks like Spark.

Earlier, I developed HyV a hybrid I/O virtualization framework for RDMA-capable network interfaces. HyV leverages the user-application isolation feature of RDMA devices in virtual environments by paravirtualizing the control path and allowing full hypervisor bypass on the data path.
