Situated at the interface of ecology and evolution, my research addresses fundamental questions about how species’ interactions with other organisms and with their environment shape patterns of plant species' distribution, diversity and range dynamics.

Chelsea Chisholm
​postdoctoral researcher

I use both large datasets and distributed experiments to address questions in community ecology and global change. Previously I have worked in arctic and alpine environments to examine how plant communities vary across environmental gradients, and the consequences for ecosystem functioning. In my current role I use demographic data to model the spread of invasive plant species across alpine ranges.

In my master thesis, I study the interactions between plants and bumblebees under climate and land use change. My project focuses on how these two factors affect variation in bumblebee communities and how this variation in turn affects plant communities in the Swiss Alps.

Loïc Liberati
​research assistant

After working more than ten years in different fields of horticulture, I obtained my masters in biogeosciences in 2017 in Lausanne . My masters project focused on the distribution and evolution of windy ridge vegetation and how it varies with substrate type in the Zermatt valley. Now I use my technical and naturalistic skills to set-up and maintain field and greenhouse experiments, making exhaustive botanical inventories and collecting data.

I obtained my B.Sc in ecology at Lanzhou University in 2014, and my M.Sc at Fudan University in 2017. I am broadly interested in trait-based community ecology. For my doctoral work, I combine modelling and field experiments to investigate the ability of functional traits to predict the outcome of novel interactions among herbaceous plants in the Swiss Alps.

Hanna Nomoto
​phd student

In my PhD I aim to understand the ecological and evolutionary responses of alpine plants to climate change. Based on a transplant experiment in the Swiss Alps, I study how morphological and demographic traits in alpine plants respond to increased temperatures (direct consequences of climate change) and changing competitive interactions (indirect consequences of climate change). I also investigate how patterns of selection on morphology and phenology are influenced by climate change. I obtained my B.Sc from University of Gothenburg and my M. Sc from Uppsala University.

Tom Walker
​postdoctoral researcher

My work focuses on understanding how climate change affects, and is affected by, the functioning of alpine and arctic ecosystems. Specifically, I borrow approaches from molecular biology, microbial physiology, biogeochemistry and ecosystem science to characterise the interplay between plants, soil organisms and their abiotic environment, and to interrogate this over multiple spatial and temporal scales.
