Dr Oskar Hagen

Scientific profile
The interdisciplinary of my interests forged an unusual career path. I first studied informatics in a 2 year formal technical education, then I graduated in Conservation Biology in Brazil. Later, I came to Switzerland and pursued my Master in Environmental Sciences at ETH. My master thesis was conducted at the theoretical biology group, with major in Ecology and Evolution at the department of integrative biology. After the Master’s I left Switzerland and worked on public and private sectors. Back in the land I obtained my Doctor of Science, where I investigated the role of past environmental conditions and eco-evolutionary feedbacks on the emergence of biodiversity. I developed an eco-evolutionary simulations framework gen3sis, available as an R-package. Combining it with new paleoenvironmental reconstructions and multiple biodiversity data, I could tackle a few, of the many unlocked potentially addressable scientific questions.
