Principal  Investigators

Samantha Hopkins Samantha Hopkins is an Associate Professor in the Department of Earth Sciences and the Clark Honors College. She earned her PhD in Integrative Biology at the University of California, Berkeley, and joined the UO faculty after a one-year postdoctoral position at the National Evolutionary Synthesis Center in North Carolina. She is interested in examining paleoecology in the Oligo-Miocene of Oregon through the lens of rodent biostratigraphy. She teaches several Honors College and Geology courses; see a list and her teaching philosophy here.
Edward Davis Edward Byrd Davis is an Assistant Professor in the Department of Earth Sciences and the Paleontological Collections Manager for the Museum of Natural and Cultural History. He received his Ph.D. in Integrative Biology from the University of California, Berkeley. He divides his time between museum curational nightmares, teaching in the UO Geology Department, and paleomammalogy research. Topics of particular interest include the evolution and development of headgear in ruminant artiodactyls, changes in macroecology over time, and conservation paleobiology.

Graduate Students

Dana Reuter is a PhD candidate working with Dr. Hopkins. Her interest in geology has lead her to work on numerous projects. She has worked as a research assistant on glacial lake sediment flow in Svalbard, Norway, as a sample collector in the Grenville orogeny in Canada, and as an REU student studying carnivoran milk tooth morphology at the Chicago Field Museum of Natural History. Her research on mammalian paleoecology focuses on paleo food web building, carnivoran tooth morphology, and the evolution of omnivory. When she is not nerding out over geology and ancient mammals she is getting lost in the woods, brewing beer, playing board games, and reading philosophy books. You can view her personal website here.
Paul Barrett is a PhD Candidate who is working with Dr. Hopkins on Feliform evolutionary history and constraint.  Paul has a BS in Geology with a minor in Zoology, and an MS in Paleontology. Paul’s past research has focused on the taxonomy and phylogeny of the Nimravidae, as well as the dental morphology of sabertooth carnivores. In between his degrees, Paul has taught English in public and private schools in both Thailand and Japan while additionally being employed as an assistant curator for the Idaho Museum of Natural History and field paleontologist for Wind Cave National Park. When not getting lost in phylogenies, Paul enjoys camping, reading, ice hockey, and a delicious cup of coffee.
Kellum Tate-Jones is a second year PhD student studying with Dr. Edward Davis. In her previous life, she was a registered nurse in Little Rock, Arkansas, but went back to school for a degree in geology after learning that rocks and bones are the best things in the world. During her graduate work, she will be focusing on the evolutionary history of pinnipeds—seals, sea lions, walruses, and their extinct relatives, particularly desmatophocids.
Holley Flora received her B.S. in Earth Sciences from Montana State University. Her undergraduate research focused on paleohistology, phylogenetics, and science outreach for dinosaur paleontology. She’s excited to be working with Dr. Edward Davis towards a Master’s and getting to research fossil mammals, specifically antilocaprids and their headgear. Holley likes dogs, cookies, dancing, and the outdoors.
Leonard Finkelman is a Masters student researching dynamics of the end-Pleistocene extinction. He has previously earned a Master of Philosophy degree in Philosophy and a Ph.D. in Philosophy from The Graduate Center at the City University of New York, where he wrote about species concepts in macroevolutionary theory. In addition to his research in the lab, Leonard teaches philosophy of paleontology as Assistant Professor of Philosophy at Linfield College, where he hopes to establish a Natural History program.
 Elena Ghezzo is a Research Fellow from the Department of Environmental Sciences, Informatics, and Statistics of Ca’ Foscari University in Venice (Italy), in collaboration with the University of Oregon and the Davis’ team. She has obtained a Global Marie Sklodowska Curie Individual Fellowship from the European Commission, for her research project regarding remote strategies for fossil finding (REFIND). She deals with high-resolution multispectral images and palaeontological databases in order to find new large palaeontological evidence exposed on desert surfaces, and to estimate the most parsimonious geographic range of extinct mammals in Europe. Her background includes anatomical studies of Pleistocene European mammals (lions, leopards, and large bovids). Moreover, she studied Oligocene anthracotheres discovered in northern Italy. She spends her free time reading and discovering new things. See her blog here

  Helena de Bastos Cruz Machado is a first year PhD student who is working with Dr. Edward Davis on Pleistocene horses. She received her B.S. in Biological Sciences at the Federal University of the State of Rio de Janeiro (Brazil) and her M.S. in Geopaleontological Patrimony at the National Museum (Brazil). On her Master’s thesis, she made a taxonomic review of the genus Equus in South America and now she’s looking forward to research Pleistocene Equus and their relation with the Great American Biotic Interchange. Helena basically spends all of her spare time watching movies and series.
 Amanda Peng is excited to be working with Dr. Hopkins towards a PhD. She graduated in 2017 from the University of Washington with a double major in Biology and Earth Sciences. Her previous research has focused on the jaw biomechanics and feeding ecologies of Cretaceous mammals, and she also has an interest in the evolution of mammalian dental characters in non-mammalian synapsids. She has worked extensively in the Hell Creek Formation of Montana, which has helped her to develop a love of all fossils. In her spare time, she enjoys drinking coffee, hanging out with dogs, and playing tennis.
