Ana I. Ayala

Ana is a limnologist and researcher at Uppsala University, Sweden. Her research focuses on process-based modelling of physical and biogeochemical processes in lakes, with a particular emphasis on the impacts of climate change on inland waters. She is especially interested in the coupling between catchments and lake systems and how these inter-actions shape ecosystem services, water quality and the management of freshwater resources.

Yeliz A. Yılmaz

Yeliz is a hydroclimatologist whose research focuses on land-atmosphere interactions, the terrestrial water cycle, and the integration of Earth observations with climate models. By combining process-based and data-driven models with satellite remote sensing, she investigates how changes in snow cover, glaciers, vegetation, and human land use impact terrestrial water and energy cycles. Her work aims to advance our understanding of climate extremes and how they evolve under a changing climate.

Thomas Alexander Davidson

Tom is a freshwater ecologist and palaeoecologist interested in how lake ecosystems respond to human pressure across a range of timescales. In recent years, he has collaborated with engineers to both apply and develop sensor systems for measuring ecosystem processes, including greenhouse gas dynamics. His work spans multiple scales, from high‑frequency measurements in lakes and mesocosm systems to decadal long‑term monitoring data and centennial‑scale palaeolimnological records, used to improve understanding of lake responses to eutrophication.

Overall, Tom’s work is driven by an exploratory approach that integrates innovative methods to better understand lake ecosystem dynamics.
