In his work, Sebastian typically leverages large datasets, such as online job postings or user profiles. In 2018, he interned with LinkedIn’s Economic Graph team and continues to study how career paths and labour mobility have changed over time with the team.

Before joining MIT in 2016, Sebastian worked as an research assistant at the Microsoft Research New England Lab and worked on several projects, including the impact of news aggregators on internet news consumption and the effect of twitter campaigns on immunizations. In 2013, Sebastian received a B.A. in Economics from Princeton University after moving to the US from Germany.
