BEHAVIOURAL ECOLOGY & EVOLUTION

current Research

I am a biologist interested in the evolution of the fascinating diversity of animal behaviours that we see in nature. How does social, life-history and environmental factors shape the evolution of a mesmerizing range of sexual signals, extended phenotypes, and collective movements that we observe across animal species? To address such a complex question, I use key study species and combine theoretical and empirical approaches. I harvest my data from all available sources, such as online databases, museum collections, and global collaborations to perform macroevolutionary research. I also design experimental research to test and propose theories for the adaptive meaning and evolution of behaviours.

I am now a postdoctoral researcher at the Genes and Behavior lab working with collective behaviour in nematodes. Currently, I am developing a project to understand the adaptive meaning of exceptional although poorly explored 3D collective phenomena.

COLLECTIVE BEHAVIOUR

Some animals finely coordinate behaviours in large aggregations. A notable example of this is the aggregations formed during swarming movement and towering in roundworms (Caenorhabditis elegans). We manipulate the social contexts and the genetic makeup of these animals to unveil the adaptive meaning, and the core mechanisms and conditions that lead to complex collective group decisions.

THE EVOLUTION OF EXTENDED PHENOTYPES

Bird nests can show an incredible diversity of shapes and materials. We are interested in investigating the factors that may be driving this diversification.

the evolution of courtship diversity

Bird species that display in Lek are under substantial pressure to attract the opposite sex. By using a macroevolutionary approach, we are investigating if under stronger sexual selection signals evolve to be more complex and repeatable.

SCIENTIFIC OUTREACH

Human societies have grown to better understand the world we live in through building scientific knowledge. Unfortunately, we witness an era of scientific denial, discouraging people to adopt environmentally friendly lifestyles. More than ever before, scientists need to ensure that the output of their research must reach and impact beyond the academic audiences.

Sciart initiative mpi-ab and merz akademie - Re-shaping Nature

I was part of an interdisciplinary partnership between the Merz Akademie, the MPI-AB and the CASCB. Four art students created stunning science outreach projects using the data from my research on fiddler crab wave display diversity and synchrony.

SCIENCE MEETS STREET ART

I was part of Science meets Street Art, a project to communicate scientific research through art.

It is a real challenge to talk about science with an audience that has limited knowledge of the field. Yet art can easily trigger the imagination, grab attention, instigate curiosity and, if well depicted, also communicate ideas.

The artist James Houl created this incredible and fun street art about my work using robotic crabs.

PUBLIC LECTURES, AUDIOVISUAL MATERIAL AND INTERVIEWS

I have been involved in several science outreach events including a Netflix nature documentary. I am always open for invitations. Please drop me an email if you need any audiovisual material or if you are looking for someone to give a talk about animal behaviour and other fun animal related subjects!

I am also an artist and I have been involved in a few projects including PhD theses and paper illustrations. I am always looking for more projects to take on and I plan to expand to street art for science outreach. Please get in touch if you are interested in my artwork.
