I am Research Staff Member (RSM) in Cloud and Computing Infrastructure group at the IBM Research Lab, Zurich, Switzerland. Before joining the lab, I finished my PhD in Computer Science at ETH Zurich under the supervision of Prof. Thomas Gross.
My main research areas are networking, operating systems, and distributed systems. Broadly speaking, I am interested in the performance aspect of systems, spanning from multi-core CPUs to distributed environments. Currently, I am investigating how modern high-performance devices (100+ Gbps network, NVMe/3DXP storage, etc.) can be leveraged in large-scale data-processing systems such as Spark, Tensorflow, serverless workloads. I am one of the founding contributors of the Apache Crail (Incubating) project.
