Lorenz is an Algorithm Engineer for Big Data, algorithms researcher, and experienced high-performance modern C++ programmer looking for new challenges. He recently defended his PhD thesis at KIT. His research focuses on probabilistic distributed algorithms for Big Data problems.
PostDoc in Algorithm Engineering — KIT
Since December 2020
Focus: static approximate membership query & retrieval (perfect hash static function) data structures. About to publish a static AMQ with sub-1% space overhead and query times on the order of a single cache miss.
Other Responsibilities include supervising BSc and MSc thesis projects and course work, coordinating a high-performance computing (HPC) project, and leading seminars and exercises.
Doctoral Researcher — KIT
December 2014 – November 2020, Algorithm Engineering Group
Focus: Parallel & Distributed Algorithms for Big Data Problems
Thesis: Communication-Efficient Probabilistic Algorithms: Selection, Sampling, and Checking, Advisor: Peter Sanders
Presented the first parallel algorithm for constructing alias tables, a popular data structure for sampling from discrete distributions and an open problem for decades; the first algorithm that requires time linear in the output size for sampling with replacement from discrete distributions
