​Dr Giulia Ghedini, Group Leader

I am fascinated by ecological communities - how they form, function, and change. I trained as a marine ecologist studying
 ecosystem stability during my PhD at the University of Adelaide (Australia, 2013-2016) with Prof. Sean Connell. We found that energy use was an important factor for stability so I did a postdoc in the lab of Prof. Dustin Marshall at Monash University to study metabolism (2016-2018). I stayed 3 more years with an Australian Research Council DECRA fellowship (2019-2021) to investigate energy fluxes in populations and communities. In December 2021 I opened my lab at the Gulbenkian Institute (Lisbon, Portugal) and I will join the School of Biological Sciences at Monash University (Melbourne, Australia) as a group leader in September 2025. My lab uses marine phytoplankton to study the interplay between species interactions, metabolism, and community functioning, exploring both ecological and evolutionary processes.

Dr Anna Lena Heinrichs, Postdoctoral researcher

I am an aquatic ecologist focusing on phytoplankton and how environmental changes shape their responses. During my PhD in the Plankton Ecology Lab at the University of Oldenburg (Germany, 2020-2023) I studied how temperature and the resources light and nutrients interactively influence the performance and morphological traits of phytoplankton. This project gave powerful insights into how resource availability influences phytoplankton's temperature sensitivity. I joined Giulia Ghedini's Functional Ecology Group in 2024 to investigate how and whether the plasticity of phytoplankton metabolic rates can be linked to community stability.

Daniela Almeida, PhD Candidate

Daniela obtained her bachelor and masters degree in Marine Biology, at the University of Algarve. Her international master degree focused on marine scientific research, where she developed a specific interest for ecosystem conservation and climate change studies. She performed her master thesis in the UK, at the Plymouth Marine Laboratory, assessing the level of resilience kelp organisms towards marine heatwaves and artificial light at night, a study done in collaboration with the Center of Marine Science of Algarve-CCMAR. She joined the Functional Ecology Laboratory group in 2023, first as a research technician and then as a PhD student.

Ricardo Estevens, Technician

Ricardo has a degree in Cell and Molecular Biology from Nova University (2017-2020) and a Master Degree in Biotechnology from the Instituto Superior Técnico of Lisbon (2020-2022), where he gained experience in microbiology. He joined the Functional Ecology lab in October 2023 as a technician where is learning about the ecology and evolution of phytoplankton before pursuing a PhD.

Simas Jasiūnas, Master student

Simas is studying a Ms. in Biotechnology at the Instituto Superior Técnico of Lisbon. In the lab, he is working on a project to improve image classification of our phytoplankton cells (and not only!).
 Former lab members
​
Charlotte Briddon
 - joined the lab for a 2 year postdoc where she led experimental evolution work to understand more about the mechanics of why certain phytoplankton are better competitors and how competition influences different biological processes within species. Now Postdoc at Uni Bristol.
​

​​Aurora Menéndez García - Aurora joined the lab to study how coevolution affects community functioning for her Master thesis project, part of the International Master in Marine Biological Resources (IMBRSea), which she completed in July 2024. Now PhD student Uni Helsinki.
​
Moritz Klaassen
- Moritz was the Laboratory Manager of the Functional Ecology group in 2022-2023, having  a degree in Environmental Science from the University of Oldenburg in Germany and a master’s degree in Marine Biological Resources from Ghent University in Belgium. Moritz now started a PhD in ecological modelling at MARE-Madeira.

Teresa Nobre - Teresa joined the lab for six months in 2022 as a research assistant, after a degree in marine biology from the University of Plymouth and a master’s degree in tropical aquatic ecology from the Leibniz Center for Tropical Marine Research (ZMT) and Bremen University. She was instrumental in setting up the lab and we are very happy that she is now pursuing her dream PhD at the University of Western Australia.

Mark Deleja - Mark joined the lab as a summer school student in 2022 with a MSc in Marine Ecology. Mark led the project: "Assessing how changes in energy fluxes with population density affect competitive outcomes in phytoplankton".

​Carolina Rattner - Carolina graduated in Biology with a specialization in  Evolutionary and Developmental Biology from the Faculdade de Ciências da Universidade de Lisboa (FCUL) in 2022. She joined the lab for an internship between November and December 2022 to kickstart her professional career and gain experience before continuing her academic courses.
