Temperature and nutrient sensitivity of denitrification: their interconnected and combined effects in a shallow eutrophic lake
Presented by Muhammad Numan Ali
Nitrogen pollution and GHG emissions, especially in aquatic environments, are critical global concerns. My research investigates nitrate reduction pathways, specifically denitrification. Exploring how cyanobacterial harmful algal blooms (CyanoHABs) and nutrients affect N transformations in freshwater lakes by using stable isotope and metatranscriptomics to uncover their influence on N removal.

The Power of Visual Storytelling for Scientific Communication
Presented by Giovan Peyrotty
Making complex scientific topics accessible to diverse audiences remains a central challenge. Since human understanding is strongly shaped by emotions, communication strategies that foster curiosity and empathy tend to have greater impact. Visual storytelling through audiovisual media helps transform abstract knowledge into meaningful human narratives. This presentation explores how adapted visual formats can engage different publics while maintaining scientific rigor.

When Science Becomes a Skillset: Building a Career from Ecology, Theory, and Data
Presented by Diego Pujoni
What may happen when a scientist steps outside academia and begins working with private companies? In this talk I intend to show how scientific training has become a powerful toolkit for solving problems. Skills such as design of experiments, inference, interpretation, and communication are essential in any field. In addition, everywhere, we will have to deal with shorter deadlines, different expectations, and the constant need to balance ethics with real-world constraints without compromising rigor. Ultimately, the talk argues that thinking like a scientist is a competitive advantage wherever decisions depend on evidence. I hope to share nice tips to help young scientists shape their own career, expanding opportunities beyond a single track.
