Collaborations

We actively collaborate with researchers, institutions, and organizations across four continents and multiple sectors — spanning international academic partnerships, domestic research networks, industry, and conservation NGOs. 

International Collaborations 

▶ 2022.03.01 – Present: Long-term collaboration with Prof. Kripal Singh, Federal University of Minas Gerais (UFMG), Brazil

• Prof. Singh is an internationally recognized expert in ecological restoration, with 55+ publications, and serves as an editor for Restoration Ecology (Society for Ecological Restoration), Ecological Solutions and Evidence (British Ecological Society), and Land Degradation & Development (Wiley).

• Our partnership has produced 17+ co-authored SCIE publications on invasion ecology and restoration, covering multiple invasive alien plant species in Korea, including Ageratina altissima, Ambrosia trifida, Rumex acetosella, Sicyos angulatus, and Solidago altissima. Key research themes include selective eradication methods, high-pressure water spraying, hierarchical structure of biotic resistance, priority effects, and ecological restoration after invasive plant management.

• Upcoming Korea–Brazil intercontinental comparative field experiment: Prof. Singh joins as an international co-investigator in a multi-scale ecological restoration research project proposed to the National Research Foundation of Korea. The project will apply an identical large-scale field experimental design to the shared invasive species Rumex acetosella simultaneously in Korea and the Cerrado tropical savanna in Brazil. The experiment will test whether the hierarchical structure of biotic resistance (priority effects > seed density > diversity effects > limiting similarity) is preserved across continents. Prof. Singh's team at UFMG will additionally apply the same framework to Brazilian invasive species (Calotropis procera, Melinis minutiflora, Mimosa pudica).

▶ 2024.03.01 – Present: Collaboration with Prof. Jane Molofsky and Dr. Kirsten Tyler, Department of Plant Biology, University of Vermont, USA

• Prof. Molofsky is an international authority on the evolutionary ecology of invasive species and plant community coexistence mechanisms, with 86+ publications in top journals including Nature Communications, PNAS, and Ecology Letters.

• Prof. Molofsky was hosted by our lab as a visiting professor from March 1, 2024, to June 1, 2024, during which we jointly conducted outdoor experiments.

• Currently, we are analyzing the nationwide Korean vegetation dataset (23,000+ plots, 2015–2024) to predict (i) the potential ecological niches of endangered native plant species, (ii) shifts in habitat suitability of major invasive alien plants under SSP1-2.6 and SSP5-8.5 climate scenarios projected to 2100, and (iii) spatial overlap between threatened native species and invasive species ranges to identify priority conservation targets.

▶ 2026 – Present: China–Korea joint research with Prof. Yanjie Liu and Prof. Lu Xiao, Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences

• A bilateral joint research project is in development with Prof. Yanjie Liu and Prof. Lu Xiao of the Northeast Institute of Geography and Agroecology (IGA), Chinese Academy of Sciences. Both research groups specialize in global climate change and biological invasion ecology.

• The project focuses on the direct effects and belowground interaction mechanisms of elevated CO₂ and drought on plant invasion, using invasive alien plant species shared by China and the Republic of Korea. Research addresses (i) differences in growth, physiology, and aboveground–belowground resource allocation between invasive and native plants under elevated CO₂ and drought, (ii) the regulatory role of allelopathy in invader competitive advantage, and (iii) the contribution of arbuscular mycorrhizal fungi to nutrient acquisition and invasion success under combined climate change scenarios.

• The collaboration draws on complementary capabilities: the Chinese team provides specialized experimental infrastructure including open-top chambers (OTC), FACE facilities, and stable-isotope (¹³C, ¹⁵N, ³³P) tracing equipment; the Korean team contributes expertise in invasion ecology, plant–soil dynamics, and biotic resistance theory.

• The project also aligns with both countries' commitments under the Convention on Biological Diversity and the Kunming–Montreal Global Biodiversity Framework, and is expected to inform regional invasive alien species risk assessment frameworks in East Asia.

▶ 2026 – Present: Collaboration with Dr. Christie Lovat, Faculty Lecturer, Bieler School of Environment, McGill University, Canada

• Reviving research from the CC-PEQ (Climate Change and Plants of Eastern Quebec) project, we are preparing a manuscript on Phragmites australis seed viability along a ~1,000 km latitudinal gradient from New Jersey to Alma, Quebec. The dataset, assembled by Dr. Christie Lovat, combines original field measurements from her doctoral research with multiple years of common-garden germination and growth-rate experiments on both native (subsp. americanus) and introduced (subsp. australis) lineages.

• The study addresses (i) contrasting seed production strategies between the two subspecies along a climatic gradient, (ii) the growing-degree-day (GDD) threshold required for viable seed production in the introduced lineage and its implications for northward range expansion, and (iii) projected shifts in invasion risk under CMIP6/SSP scenarios. A McGill senior undergraduate, Mr. Jacob Zweig, is conducting the analyses as an honors project and will be considered for co-authorship. 

▶ 2019.01.01 – 2023.12.31: Lead Author of the IPBES Invasive Alien Species Assessment Report

• As Lead Author representing the Republic of Korea, I contributed to Chapter 6 of the Thematic Assessment Report on Invasive Alien Species and their Control of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), collaborating with international scholars on governance and policy options for managing biological invasions and contributing to the development of international standard policies.

▶ 2020.01.01 – 2022.12.31: Collaboration with Prof. Karin Kettenring (Utah State University, USA) and Prof. Sylvie de Blois (McGill University, Canada)

• Co-authored a review paper synthesizing ecological principles for maximizing resistance to invasion in restored plant communities, published in Ecological Engineering.
