Exploring Living Dinosaurs
An integrative approach to ecology & evolutionary biology research
An integrative approach to ecology & evolutionary biology research
Welcome to the De Silva Lab at the University of Utah.
We explore the immense biodiversity of our planet and strive to understand the processes that generate this remarkable diversity, with a primary focus on birds as a model system. Our research uncovers unknowns in ecology and evolution through a multidisciplinary approach that integrates fieldwork, molecular lab techniques, bioinformatics, museum-based studies, ecological niche modeling, biogeography, and citizen science. Our work is strengthened by collaborations with experts in bioinformatics, genomics, computer science, engineering, architecture, mathematics, optics, geology, paleontology, and statistics, making our research highly integrative. While working to conserve biodiversity, we also seek bioinspiration—drawing innovative insights from the natural world.
We investigate the rich diversity of birds across populations, species, families, and orders. We analyze the relationships between birds at these different hierarchical levels.
We explore genetic diversity both within and between species, as well as within populations. We explore the relationship between genotype and phenotype in birds
We examine variations in size, shape, plumage color and other traits within and between bird species, exploring adaptations across diverse environments.
Why do birds build elaborate nests? An eco-evolutionary study using weaverbirds and icterids as convergent model systems
We study how different organisms interact with their respective environments and how these interactions shape their life histories, using field studies, ecological niche modeling, and phylogenetic comparative methods.
We explore intriguing behavioral phenomena in the bird world, such as brood parasitism, cooperative breeding, polygyny, and coloniality.
