Gema Hernan is a postdoctoral fellow at the Mediterranean Institute for Advanced Studies working in coastal systems in the Fiona Tomas lab. Her research interest is to understand how environmental factors or other ecological state changes affect the processes and mechanisms of coastal systems at different levels, from individuals to communities, and at different spatial and temporal scales. Most of her work focuses on marine macrophytes and fish communities combining observational and experimental approaches, and modelling tools. Currently she is exploring how ecological changes such as invasive species or human stressors affect them seagrass systems. She is also collaborating in a project looking at accumulation of microplastics in these systems. Dr Hernan enjoys sharing her research with the public and inspiring students. She has participated in outreach activities such as lab open doors and women in science events and judged regional science fairs.

Tenured Scientist
Mediterranean Institute for Advanced Studies (IMEDEA-CSIC-UIB)
Ana Sanz (PhD in Biology, University of the Balearic Islands) is a Ramón y Cajal Fellow at IMEDEA. Before joining IMEDEA she has worked at CEFE-CNRS Montpellier (Marie Curie Intra European Fellowship) and at the Doañana Biological Station (EBD-CSIC). Her research trajectory has been focused on theoretical and applied aspects of animal ecology, demography and population dynamics with special emphasis on conservation biology. She has led a long-term research program on seabirds since 2003. Dr Sanz holds a comprehensive knowledge of advanced individual-based modelling techniques (e.g., multi-event capture-recapture models) and Population Viability Analysis. Part of her research focuses on methodological advances in the field of animal demography and population dynamics, which she combines studies on basic ecology (e.g., evolutionary trade-offs, individual strategies), animal behaviour, and conservation biology (e.g., population viability of endangered species, evidence-based management and demography of invasive species).
Tenured Scientist

Giacomo Tavecchia is currently a Tenured Scientist and head of the Department of Animal and Microbial Biodiversity at IMEDEA. He obtained his Ph.D. in “Ecology and Evolution” in 2000 at the University of Montpellier (France) and developed his postdoctoral research at several EU Institutes (Cambridge University, Imperial College of London and University of Olso). His research focuses on animal demography and on the evolution of life-history traits. It is characterized by a numerical approximation in a classical as well as Bayesian statistical framework. Giacomo has worked with many animal species from mammals to insect and is currently responsible for the long-term monitoring of three species of vertebrates in the Balearic Archipelago. Since 2011 he teaches an international course on capture-mark-recapture analysis applied to the conservation of animal populations. Since 2017 he is the head of the Animal Demography and Ecology Unit at the IMEDEA and responsible for the scientific blog www.animaldemography.blogspot.com that relates the activity of the group.
