About Me

My name is Robin Rehrmann, I am in my final year as PhD student. My topic is Merging Queries in OLTP workloads.

I do my PhD at the SAP HANA Campus in Walldorf with Prof. Lehner of the TU Dresden. I joined the Data Management Lab in 2016, because Prof. Binnig is my Co-Supervisor.

Before doing my PhD, I have completed a dual B. Sc. degree with Fraunhofer SCAI, where my thesis focused on speeding up the LU-transformation within a pipeline of CPU and GPU. I continued doing my M. Sc. at the KIT with focus on operating systems and parallel computing; my thesis was about solving linear algebra systems with approximate computing on CPUs and GPUs.

Besides databases, I like people, going to church, playing board games, and listen to, discuss, make and write music.
