Juliana Velez-Gomez
Postdoctoral Scholar, Biology
BioJuliana Vélez (she/her) is a postdoctoral researcher with the Natural Capital Project, studying land-use change and vector-borne disease risk. Her research applies quantitative ecological methods to understand interactions among species, their habitat, and anthropogenic disturbance. Juliana's work incorporates ecological experimentation and collaborations with decision makers to assess the effectiveness of conservation actions for improving ecosystems. She conducts her research under open science standards and has contributed to the development of online resources for reproducible research, including the publication of guides, datasets, and code related to statistical modeling and data processing using artificial intelligence. Juliana earned her Ph.D. in Conservation Sciences from the University of Minnesota.

Peter Vitousek
Clifford G. Morrison Professor of Population and Resource Studies and Professor of Earth System Science, Emeritus
Current Research and Scholarly InterestsVitousek's research interests include: evaluating the global cycles of nitrogen and phosphorus, and how they are altered by human activity; understanding how the interaction of land and culture contributed to the sustainability of Hawaiian (and other Pacific) agriculture and society before European contact; and working to make fertilizer applications more efficient and less environmentally damaging (especially in rapidly growing economies)

Ayelet Voskoboynik
Assistant Professor (Research) of Biology
Current Research and Scholarly InterestsWe study the mechanisms by which animals differentiate between self and non-self, and how stem cells and immune cells coordinate to form tissues during development, regeneration, transplantation, and aging. By leveraging the natural stem cell-mediated development, regeneration, and chimerism in the colonial chordate Botryllus schlosseri, we investigate stem cell competition and the decline in regenerative capacity during aging.

Virginia Walbot
Professor of Biology, Emerita
Current Research and Scholarly InterestsOur current focus is on maize anther development to understand how cell fate is specified. We discovered that hypoxia triggers specification of the archesporial (pre-meiotic) cells, and that these cells secrete a small protein MAC1 that patterns the adjacent soma to differentiate as endothecial and secondary parietal cell types. We also discovered a novel class of small RNA: 21-nt and 24-nt phasiRNAs that are exceptionally abundant in anthers and exhibit strict spatiotemporal dynamics.
