I am broadly interested in the mechanisms that allow populations to adapt to different environmental conditions (e.g. seasonal and/or clinal variation), particularly when there is some stochastic environmental variation. My current research projects are focused on understanding the repeatability and predictability of evolution in a single environment (in collaboration with Pedro Simões and Margarida Matos from cE3c) and the impact of different environments on the distribution of fitness effects of new mutations (in collaboration with Dan Bolon from UMass). To tackle these questions I use a combination of experimental evolution data, statistical analyses, simulations and theoretical modeling.
I started my academic path in the Biology program at Faculdade de Ciências da Universidade de Lisboa (FCUL) graduating in 2006. Throughout the program I had some cool classes that guided me towards one of my favorite questions in evolutionary biology: How do species adapt to a new environment? So, I did my master’s thesis in Margarida Matos’ laboratory (FCUL) working on the “Evolutionary changes during laboratory adaptation: Analysis of morphological, behavioral and life history traits.” From 2010-2015, I developed my PhD thesis under the supervision of Margarida Matos (FCUL) and Mauro Santos (Universitat Autònoma de Barcelona) on “The role of history, chance and selection during adaptation: an integrated perspective.” You can say that up until now I have been studying how populations adapt to a common environment, using experimental evolution and looking at different biological levels (phenotypic, karyotypic and genomic).
I was a postdoc in Claudia Bank’s lab at the Instituto Gulbenkian Ciência (IGC) from 2016 to 2019.
Now, I’m in the lab of Sara Magalhães at the Centre for Ecology and Environmental Changes.
