Since Autumn 2013, I am a PhD candidate in the ETH Systems Group, working under the supervision of Prof. Dr. Gustavo Alonso. My research focuses on database systems, in particular distributed query processing on modern hardware. Prior to joining the Systems Group, I received my Master of Science degree from ETH Zurich in September 2013, with my focus area being distributed systems. My master thesis on distributed join algorithms was supervised by Prof. Dr. Donald Kossmann and Dr. Simon Loesing.

| Join Processing with RDMA: Modern communication mechanisms, such as Remote Direct Memory Access (RDMA), have significantly lowered the costs of large data transfers. However, these performance advantages can only be leveraged through interleaving the computation with the network communication and through careful management of the RDMA buffers used for transmitting and receiving data. In this project, we investigate how join operators need to be designed in order to take full advantage of all the features provided by modern low-latency, high-throughput networks. Our results show that hardware-concious distributed join algorithms can run on thousands of cores and exhibit good performance and scalability. |  |
| Rack-Scale Data Processing Systems: Rack-scale computers are becoming the building blocks of modern data centers. They are characterized by new hardware technologies that promise terabytes of main memory and thousands of processor cores connected through high-speed networks. These systems face a variety of challenges, one of which is the orchestration of the processing and communication resources in order to achieve maximum performance. In this project, we explore how to design databases for rack-scale systems. We investigate several approaches for distributing a state-of-the-art relational database on a modern rack-scale cluster and evaluate these techniques in terms of performance, fault-tolerance, scalability, and elasticity. |  |
