M. Luke McCormack, PhD

Research Biologist, Tree Root Biology

Content Detail

Luke McCormack leads The Morton Arboretum’s Root Biology Research Group, which seeks to understand how functional root traits and processes vary among plant species, among populations of the same species, and even within individuals over time. The group applies this information to assess and predict the success of trees in multiple environments.

As roots and their activities below ground are often the least understood components of the integrated plant system, gaining a better understanding of these enigmatic organs has tremendous capacity to improve the appreciation and management of trees. Led by McCormack, the Arboretum’s Root Biology Research Group uses modeling and field-based research to interpret patterns of trait diversity and plant responses to their environment across spatial scales leveraging tools from multiple disciplines including plant physiology, plant and microbial ecology, and whole-ecosystem science.

McCormack’s guiding vision is to fundamentally change how belowground systems are perceived in both basic and applied research communities, highlighting the importance of root and rhizosphere processes to the overall health, resilience, and productivity of forest ecosystems.

Accomplishments

Luke McCormack’s research influence includes his contributions to large collaborative groups working across organizations on integrative worldwide databases, such as the free and open access Fine-Root Ecology Database (FRED), the largest database of root traits, of which he is the co-founder and lead.

McCormack has served as a thought leader in several global analyses—many of which used the Fine-Root Ecology Database—including publications in Nature, Nature Ecology and Evolution, New Phytologist, and Science Advances.

McCormack was noted as a “Highly Cited Researcher” in 2023 and 2024 by Clarivate.

Among his other top-cited research, McCormack led a 2015 foundational paper published in New Phytologist, entitled “Redefining fine roots improves understanding of below‐ground contributions to terrestrial biosphere processes,” which has been cited over 1,200 times.
