BIO
I have a background in environmental studies (PhD @LMU, M.Sc., @TU Munich) and business (C-level consulting at Kearney, Audi). Before founding Pina Earth, I co-led the Center for Digital Technology and Management (CDTM) in Munich for the four years of my doctoral research. At CDTM, I taught entrepreneurship and was responsible for partnerships (with e.g. Siemens AI, Adidas) as well as recruiting. CDTM is also where I met my co-founder, Florian.
