About me
I am a behavioural ecologist fascinated by the intricacies of social interactions in nature. I'm a Junior Group Leader at the University of Lisbon/MARE. I did my PhD at the University of Lisbon, a first Post-doc at MARE - ULisbon, a Post-doc at the University of Hong Kong, and a Post-doc at HIMB - University of Hawai'i.
My research focuses broadly on the development of complex animal behaviour, how this behaviour modulates biodiversity and how human impacts can lead to cascading effects by behavioural alteration. The majority of my research is centred around five key questions:
1) How does complex marine animal behaviour evolve and develop?
2) What are the mechanisms behind behaviour?
3) What is the contribution of behavioural diversity to the health of ecosystems?
4) How sensitive is marine animal behaviour to human impacts?
5) How can new and emerging technologies be applied to marine behavioural, ecological and conservation questions?
Within these questions, I aim to shed light on both fundamental behaviour and ecology questions (questions #1, #2 & #3), as well as applied environmental and impact questions (questions #3 & #4) and solutions (question #5).
Much of my work has explored these questions using large-scale experiments (e.g. reef manipulations, mesocosms), field experiments, laboratory simulations, and molecular work. Increasingly, my work uses new emerging technologies (e.g. AI, remote cameras) to achieve my research goals.
I love to hike, cook, travel, and scuba dive! I can also be really clumsy with coffee mugs next to keyboards (accidents have happened).
