I completed my Bachelor´s Degree in Urban Studies ("Urbanistik") at Bauhaus University in Weimar. It is a multi-disciplinary programme, paying tribute to the complexity of today´s cities, consisting of law, economics, engineering, architecture, sociology, history and more. As part of the programme, I also studied two semester at the Pontifica Universidad Católica de Chile in Santiago de Chile. I could gain work experience during my studies as an Intern for a Weimar-based office, that specialized on alternative (bottom-up) project development. After my studies, I completed an Internship of 6 months at Drees & Sommer Switzerland, Blue City - Integrated Urban Solutions, that follows a global approach to implement smart, sustainable and human-centred urban development. Currently, I am working at Seiler & Seiler, a Zurich-based spatial planning studio, that develops smart tools and methodologies for Swiss urban development.
