Lab Overview

Our lab focuses on understanding the complex relationships between plants and their environment, and the evolution of plant physiological adaptations.

We employ techniques from eco-physiology and evolutionary ecology to investigate:

  • leaf, xylem and root adaptations
  • whole plant co-ordination of function
  • the effects of habitat alteration and climate change
  • plant responses to stressful events and environments

Locate, meet and collaborate with Rhododendron experts and researchers world-wide



May 14, 2018 We welcomed new summer research interns Fiona Duong and Bryce O'Brien to the lab! Fiona will be working on Rhododendron comparative leaf anatomy, and Bryce will be conducting analysis of photoprotective pigment response to cold acclimation in six populations of Rhododendron minus.

February 21, 2018 New paper published, with beautiful and informative artwork done by Sharon Danielson. Medeiros JS and SC Danielson. 2018. Renewed interest in whole-plant physiology sheds light on the complexity of plant stress response architecture. Tree Physiology

January 4, 2018 PhysFest2 is coming to Holden Arboretum July 15-19, 2018. This event will provide graduate student training in ecophysiology techniques, create a data set on canopy physiology using the canopy walk and emergent tower at Holden, and provide training on scientific communication for the public. For more information check out the PHYSFEST2 website

September 6, 2017 Welcome new graduate student Samia Hamati to the lab. Ms. Hamati will be jointly advised by Dr. Medeiros and Dr. David Ward, the KSU Art and Margaret Herrick Endowed Professor of Plant Biology. Samia will study how environmental factors such as competition for light affect growth and physiological stress tolerance in the evergreen shrub Juniperus virginiana, and how this relates to the recent expansion of the species range into mid-western grassland ecosystems.

August 3, 2017 A Rhododendron Research Network has been established in conjunction with the American Rhododendron Society. Dr. Juliana Medeiros and colleague Dr. Erik Nilsen (Virginia Tech) will lead the network, which will focus on creating opportunities for international collaborations and citizen science opportunities in Rhododendron. You can learn more about the network and follow our progress at Rhodo-Research.net

June 14, 2017 New paper out in the American Journal of Botany "Decoupled leaf and root carbon economics is a key component in the ecological diversity and evolutionary divergence of deciduous and evergreen lineages of genus Rhododendron".
