Jessica Kenigson, Ph.D.
Research description: Jessica completed her Ph.D. on causes of sea level variability in the North Atlantic Ocean in the Department of Atmospheric and Oceanic Sciences at the University of Colorado Boulder in 2018. She also completed an M.S. in Applied Mathematics at the University of Colorado Boulder.
Jessica’s research at Yale focuses on how changes in the Arctic Ocean circulation influence the global ocean circulation and Earth’s climate. She analyzes ocean and atmospheric measurements spanning decades to understand the far-reaching consequences of Arctic Ocean change, including influencing sea level rise in the North Atlantic Ocean. Jessica is working with Professor Mary-Louise Timmermans in the Department of Geology and Geophysics.
Fellowship dates: September 2018 - August 2020
Morgan Furze, Ph.D.
Research description: Morgan Furze is a Donnelly Postdoctoral Fellow working with Professor Craig Brodersen in the School of Forestry & Environmental Studies at Yale University. Her research in the Brodersen Lab focuses on whole-plant carbon dynamics and its implications for how plants function in response to global change. She integrates tools from plant physiology, forest ecology, and isotope biogeochemistry with micro-CT imaging to explore carbohydrate storage and allocation in ecologically and economically important plants, especially trees. Morgan received her BA from Bucknell University and PhD from Harvard University.
Fellowship dates: July 2019 - June 2021
Anthony Baniaga, Ph.D.
Anthony’s research at Yale focuses on how whole genome duplication affects plant form, function, and ecophysiology using the taxonomically difficult viburnum denatum species complex (Adoxaceae) as a model. Building upon previous work in this system, Anthony is currently documenting the distribution of polyploid populations in this complex. Through the support of the Donnelley Fellowship and the mentorship of Professor Michael Donoghue in the Department of Ecology & Evolutionary Biology, Anthony will ultimately link how having an extra set of chromosomes leads to changes in leaf morphology, function, and where these plants are able to inhabit.
Maria Rebolleda-Gomez, Ph.D.
Freya Rowland, Ph.D.
Catherine Davis, Ph.D.
Research description: Advait will be studying the impacts of human hunting and climate change on the megafaunal extinction in India. He will use tools including faunal analyses, stable isotopes, bone surface modification, and geochronology to understand the anthropogenic and environmental context of this extinction. The recent extinction of large terrestrial vertebrates has been the focus of paleontological, archeological, and ecological research for decades, but the causes are poorly understood in some of the most biodiverse regions of the world, like the Indian Subcontinent. India unlike large parts of the world, retains several species of large mammals such as rhinos and elephants. Advait’s goal is to understand why so many large species have survived in this region.
Fellowship dates: June 2020 – May 2022
Research description: James has spent the last six years investigating the causes and consequences of individual behavioral variation. At YIBS he will study how ecosystems drive the evolution of diversity in predator behavior and how the evolution of behavioral diversity affects ecosystems. Species-diverse ecosystems are predicted to constrain the evolution of trait diversity within predator species, and this trait diversity increases how many prey they kill, thereby increasing plant growth. James will test this using experimental evolution to create predatory insect populations with low or high levels of diversity in the behaviors they use to hunt prey. These predators will then be deployed in meadows to test how their behavioral traits affect ecosystem structure. Teasing apart these intricate eco-evolutionary dynamics could help explain how ecosystems function, potentially allowing us to use artificial evolution to shape ecosystems.
Fellowship dates: September 2020 - August 2022
Research description: Thomas’s research focuses on understanding how climate impacts trends in biodiversity both in the modern ocean and the geologic past. He uses a combination of tools in his research including stratigraphy, paleontology, and organismal ecophysiology to answer questions such as how changes in the redox structure and temperature of Earth’s oceans influenced early animal evolution. In addition, his work has focused on understanding how warming oceans in the coming centuries will impact the range size of species and latitudinal diversity patterns. At Yale, Thomas will be focused on understanding how climate change will impact the physiology of seafloor sediment-dwelling animals that are found throughout the global ocean. These animals play a critical role in mediating several key marine biogeochemical cycles, including the coupled carbon-phosphorous-oxygen cycle, the sulfur cycle, and organic carbon burial.
Fellowship dates: October 2020 - September 2022
Research description: Natasha is an evolutionary biologist interested in understanding how organismal diversity evolves and the mechanisms that can constrain or facilitate complex evolutionary outcomes across species. At Yale she will focus on understanding the mechanisms that drive the evolution of complex life cycles using the polyp and jellyfish life stages of cnidarians. The goal of her work is to better understand the relationship between jellyfish reduction and polyp specialization and investigate whether disruption of cell differentiation can serve as a developmental mechanism underlying the loss of complexity. The loss of complexity in one phase of a life cycle is often associated with an increase in another phase of the life cycle. Overall, her work investigates the dynamics of evolutionary constraints, how these shape changes in organismal complexity, and the developmental basis of those changes.
Fellowship dates: December 2020 – November 2022
