Earlier in his career, Reiner conducted research visits at Harvard, Oxford, and Manchester, deepening his work in private equity performance, venture capital, and entrepreneurial finance. His research established foundational frameworks for measuring GP skill, performance persistence, and deal-level value creation across buyout markets.
Reiner completed his PhD at the University of Wuppertal in 2007 and his habilitation at TUM in 2012. From 2013 to 2015 he held the Chair of Entrepreneurial Finance at Friedrich-Alexander Universität Erlangen-Nürnberg before taking up his current Chair of Entrepreneurial Finance at TUM in 2015, where he continues to teach and publish. His research has been cited extensively across both academic and institutional investment contexts, and directly informs QFT's approach to separating skill from luck in fund manager evaluation.
