Doctor Renée Marchin Prokopavicius

Renée ProkopaviciusDr. Renée Marchin Prokopavicius joined Hawkesbury Institute for the Environment (HIE) in August 2017. She currently works with Professor David Ellsworth on the Which Plant Where? project, researching how to create urban green spaces that are resilient to future heat waves and drought. She is determining the thermal and drought tolerances of current and potential horticultural plant species/varieties.

Dr Prokopavicius' research aims to improve predictions of the effects of climate change on terrestrial and urban ecosystems. Two global changes that affect plant productivity are increasing temperature and drought. She primarily uses ecophysiological approaches to understand how plant traits determine which species or genotypes succeed in changing environments. Her research has focused on plant traits related to water relations and growth, such as photosynthesis, stomatal conductance, transpiration, and water use efficiency. She has worked in a diverse range of terrestrial ecosystems, from temperate forests to subalpine grasslands to agricultural cropping systems.

Dr Prokopavicius has recently completed a postdoc at the University of Sydney, where she studied how climate change is affecting carbon fluxes of mountain grasslands in the Snowy Mountains, Australia. She obtained her PhD in 2013 from North Carolina State University, where she studied how phenology and transpiration of temperate forests will be affected by warming. She has also worked as a Rangeland Technician for the Bureau of Land Management in California, USA to monitor the effectiveness of efforts to restore degraded aspen stands to the landscape.
