Maren Vitousek

Dr. Maren Vitousek focuses on the intricate dynamics of how organisms adapt to environmental challenges, with a particular emphasis on phenotypic flexibility in response to stressors. As an Associate Professor in Ecology and Evolutionary Biology at Cornell University, she leads a research team that delves into the complexities of stress resilience and phenotypic plasticity. Her work is pivotal in understanding the evolutionary patterns and processes that govern how different species, especially birds like tree swallows, cope with changing environments. In her research, Dr. Vitousek employs a combination of field studies and laboratory experiments to explore the variability in stress responses among individuals and populations. By using tree swallows as a model species, her lab seeks to unravel the reasons behind the diverse responses to environmental stressors. This research is crucial in shedding light on the evolution of ecophysiological traits and the role of glucocorticoids in stress resilience. Dr. Vitousek's interests extend to the interplay between social interactions and stressors, and how these factors influence individual biology. Her investigations aim to elucidate the evolutionary significance of endocrine traits, examining how natural and sexual selection shape these characteristics over time. Her work contributes to a broader understanding of community ecology and population biology, providing insights into the sustainability of ecosystems. Beyond her research, Dr. Vitousek is dedicated to education and mentorship. She teaches courses in evolutionary biology, professional development in ecology and evolutionary biology, and physiological ecology. Her commitment to teaching ensures that students gain a comprehensive understanding of organismal biology and the environmental factors that influence behavioral traits. Dr. Vitousek's contributions to the field are recognized through her innovative approaches to studying the evolution of hormones and stress responses. Her research not only advances scientific knowledge but also informs conservation efforts by highlighting the importance of stress resilience in maintaining biodiversity. Through her work, she continues to inspire the next generation of ecologists and evolutionary biologists.
