Olga Ovcharenko

Graduate student at ETH Zurich

Olga Ovcharenko is a first-year Data Science master’s student at ETH Zurich, Switzerland. Olga’s interest in data science started with her undergraduate Data Management course at Graz University of Technology, Austria. She mainly focused on distributed storage, analysis, and stream processing. Olga was part of the DAMSLab headed and supervised by Prof. Matthias Boehm. Olga had been working on the ExDRa project (exploratory data science over raw data) and contributing to the federated backend of Apache SystemDS, an open-source ML system for the end-to-end data science lifecycle. She implemented federated components such as linear algebra operations and low-level instructions. Olga is Apache SystemDS committer and has coauthored joint SIGMOD and CIKM papers with Siemens, TU Berlin, DFKI, and TU Graz. For her bachelor’s thesis, Olga built a distributed data generator to scale real datasets preserving statistics and error distribution of the original data. Additionally, Olga is worked with Prof. Theodoros (Theo) Rekatsinas. Currently, Olga is working on her semester project with Prof. Valentina Boeva.
