Louise Comas is a Plant Physiologist with the USDA Agricultural Research Service (USDA-ARS) on campus at Colorado State University. She received her PhD from the Pennsylvania State University in University Park and was research faculty at Penn State and at the University of California in Davis prior to her current position with the USDA-ARS. She studies plant functioning under water stress, effects of co-limitations of water and nitrogen on plants, as well as functional root traits related to soil resource acquisition and interactions with soil microbes.

As a 2026 Fellow, she will exchange best practices and ideas related to precision management of water, nutrients, and agronomic systems in semi-arid environments in collaboration with host Dr. Vasileios Tzanakakis, researchers and students at the Hellenic Mediterranean University (HMU) during a series of seminars and discussions. This exchange will foster collaboration among US and Greek scientists working in water-limited environments and contribute to HMU's long-term efforts to strengthen research excellence, promote international scientific collaboration, and prepare future collaborative research initiatives addressing the challenges of sustainable agriculture under water-limited environments.
