I am from Barcelona. I have a bachelor in Economics from Universitat Pompeu Fabra. I moved to Paris in September 2013 to join the master program Public Policies and Development at the Paris School of Economics, which I graduated from in July 2015. I did my master thesis with Gabrielle Fack on the impact on housing policies. In September 2015 I started the PhD in RITM in Université Paris-Sud-Paris Saclay on the same topic with Gabrielle Fack and Miren Lafourcade. I’ve worked on housing vacancies, property tax, airbnb and air traffic.
