Irene Gregory-Eaves is an Associate Professor in the Dept. of Biology at McGill University. The goal of Irene's research is to provide a long-term and large-scale understanding of the structure and functioning of lakes as well as insight into how human activities alter these ecosystems. To achieve these goals, Irene's group combines contemporary limnological studies with analyses of the sediment record. Her work incorporates physical, chemical and biological aspects, but in large part focuses on organismal responses to biotic and abiotic drivers. Her work in paleolimnology has applied primarily classical approaches, but she has recently entered the world of environmental DNA.

Isabelle Domaizon is a researcher at the Centre Alpin de Recherche sur les Réseaux Trophiques et les Ecosystèmes Limniques (CARRTEL), Institut National de Recherche en Agronomie, Thonon-les-Bains, France. She is a limnologist, and her main research interests deal with the structure and dynamics of lacustrine food webs, the role and diversity of microbial communities in pelagic food webs, and the effects of local and global regulating factors on microbial compartments. Isabelle commonly applies molecular approaches in her work to answer questions regarding the diversity of protists and phytoplankton. She has recently published several studies analyzing the DNA archive in lake sediments (for instance, reconstructing the history of cyanobacteria in alpine lakes).
