Dr. Alex White

Job Titles:
  • Data Scientist
Alex White's areas of scholarly expertise include statistical modeling in biogeography, quantitative ecology, ornithology, and community phylogenetics. Dr. White's research focuses on how ecological and evolutionary forces (e.g., dispersal, range expansion, competition, and speciation) interact to mediate broad scale patterns of biodiversity and how those interactions are influenced by local ecological dynamics. Most of this research focuses on birds, though he compares avian patterns with those of other taxonomic groups including plants, mammals, and invertebrates. This work combines traditional methods in ecology and evolution with modern advances in statistics and computation, particularly those in machine learning and data science. As a Biodiversity Research Data Scientist in the Smithsonian Data Science Lab, he leads projects that leverage digitized museum collections as well as applications of computer hardware technology in edge uses of machine learning for field studies of animal and plant ecology. He is an Associate Editor for Ornithology. Alex received his Ph.D. in Ecology and Evolution at the University of Chicago, where he developed these and other questions to study the evolution and ecology of Himalayan birds.

Dr. Jenna Ekwealor

Job Titles:
  • Biodiversity Genomics Postdoctoral Fellow
  • Postdoctoral Fellow
Jenna Ekwealor is a Biodiversity Genomics Postdoctoral Fellow in the Data Science Lab. She earned a B.S. in Biology from Purdue University, a B.A. in Religious Studies from Indiana University, a M.S. in Environmental Science from California State University, Los Angeles, and a Ph.D. in Integrative Biology from University of California, Berkeley. Her research focuses on plant adaptations to extreme environments, using dryland mosses in the genus Syntrichia as a model system for adaptive abiotic stress tolerance. These small plants have found a way to only truly "live" when enough water is present and dry out and go quiescent when water is absent. For desert mosses that may be most of the time! Yet, Syntrichia species are able to quickly begin to grow and thrive again, while recovering from damage that accumulated while they were desiccated. In the Data Science Lab, Jenna will explore the evolutionary history of the genomic underpinnings of tolerance of UV and desiccation in Syntrichia and in land plants in a phylogenetic context. She also looks forward to beginning new, integrative projects in the realms of plant evolutionary eco-physiology or life history using phylogenomic, metabolomic, or other bioinformatic techniques.

Spillane recently finished her Ph.D. in Molecular and Evolutionary Systems Biology at the University of New Hampshire where she used phylogenomics and comparative genomics to learn more about trait evolution in animals, and particularly marine invertebrates. As part of the Data Science Lab, she will work on developing machine learning models to address the problem of DNA sequence contamination. She is generally interested in improving genomic and bioinformatic methods to better study non-model and under-represented organisms.

Dr. Mirian Tsuchiya

She has a B.S. in Biology from the Universidade Estadual de Londrina, an M.Sc. in Zoology from the Pontificia Universidade Católica do Rio Grande do Sul and a Ph.D. in Environmental Science and Policy from the George Mason University. Her dissertation research focused on using whole genome sequencing, targeted enrichment of ultraconserved elements (UCEs) and mitogenomes under a phylogenomics framework to assess questions regarding the biogeography, taxonomy, and evolutionary history of Neotropical mammals. Mirian worked on a variety of biodiversity genomics projects with the Data Science Lab and now an ORISE fellow at the Food and Drug Administration Center for Applied Food Safety.
