Matthias studied Systematic Musicology at the University of Hamburg, where he focused on quantitative models of auditory perception. For his master's thesis, he applied multidimensional scaling to inform a timbre perception model and graduated with honors. In the course of this work he developed an interest in working with data and programming, so he went on to substantiate his understanding of these topics by passing several certified programs covering Python, Data Science and Machine Learning at MITx and the University of San Diego.
Before diving into Tableau and Alteryx at the Data School, he has been a proficient contributor to the open source landscape, writing Python scripts for data mining and programmatic fetching from APIs, also touching on Web3 protocols and querying blockchain data. Most recently before joining the Data School, he had designed and maintained a tweet mining solution quantifying engagement metrics of target audiences for a Web3 protocol, which to this day is regularly querying Twitter and appending to the database without fail.
Away from the screen he is passionate about many things, but above all music, which he enjoys listening to as well as performing with his band.
