Sebastian Schaffert
Sebastian Schaffert is a software engineer and researcher. He was born in Trostberg, Bavaria, Germany on March 18, 1976 and obtained his doctorate in 2004.
Before moving out of research, he was very active in the Semantic Web, Linked Data and Multimedia Semantics fields, his works received more than 1.800 citations. He is a contributor to open source projects, among those Apache Marmotta and participated in several European FP6 and FP7 research projects such as REWERSE, KiWi, IKS and MICO.
Education
In April 2001, he graduated in Computer Science with a thesis on "Grouping Structures for Semistructured Data: Enhancing, Data Modelling and Data Retrieval".In December 2004, he obtained his doctorate at the faculty of Mathematics, Computer Science and Statistics at the Ludwig-Maximilians-Universität of Munich with the thesis "Xcerpt: A Rule-Based Query and Transformation Language for the Web".
Career
In August 2005, he worked as senior researcher and project manager at the Salzburg Research Institute where he is currently head of the Knowledge and Media Technologies group.In 2006, he also became scientific director of the Salzburg NewMedia Lab.
In 2009–2010, he taught at the Fachhochschule of Salzburg
In 2013, he co-founded Redlink and held the CTO position.
In December 2014, he joined Google at Zürich, where he currently works as Site Reliability Engineering Manager.
