Dr. Melissa McHale is an urban ecologist whose internationally recognized work bridges cutting-edge theory and applied science to inform decision-making in cities. Her research advances understanding of how urban ecosystems function and how nature-based solutions can be mobilized to address climate change, urban heat, and equity challenges in rapidly urbanizing regions.

She received a BS in Conservation Ecology from Rutgers University and a PhD in Ecology from Colorado State University, and completed postdoctoral training with the Central Arizona–Phoenix Long-Term Ecological Research (CAP-LTER) program at Arizona State University. Prior to joining the University of British Columbia, she held faculty positions at North Carolina State University and Colorado State University. She also served as an Honorary Research Fellow at the Wits City Institute at the University of the Witwatersrand in South Africa.

Dr. McHale is currently a faculty member at the University of British Columbia, where she leads the Urban Ecology and Sustainability Lab. Her research program focuses on developing science for climate-resilient, nature-rich cities, with particular emphasis on urban heat, ecosystem service provision, and the structure–function–service–equity relationships that shape urban landscapes. Her work is deeply collaborative, co-produced with cities, practitioners, and community partners, and is designed to translate directly into planning, policy, and implementation.

Her contributions have been recognized through multiple awards and competitive grants, including a National Science Foundation Urban Long-Term Research Area (ULTRA-Ex) award and the Distinguished Ecologist Alumni Award from Colorado State University. She is also a recipient of the Peter Wall Fellowship at UBC, supporting her leadership in building a long-term, transdisciplinary research platform for climate resilience in British Columbia.

Dr. McHale has a strong track record of leadership at the science–practice interface. She founded the Urban Sustainability Research Network in Fort Collins, Colorado, fostering collaborations among academics and practitioners to develop impactful, solutions-oriented research. She continues to serve as a scientific advisor to cities, government agencies, and non-profit organizations, contributing expertise on urban forestry, climate adaptation, and ecosystem services.

Her international research program includes long-standing work in South Africa and across the Global South, where she studies sustainable urbanization and resilient social–ecological systems. This work builds partnerships among scientists, conservation organizations, and local communities, and has supported NASA-funded research on urbanization hotspots and ecosystem service dynamics in South Africa, Ethiopia, and Nigeria. Through this program, she creates opportunities for students to engage with diverse knowledge systems and to work alongside historically marginalized communities facing complex environmental and social challenges.
