Who are we? What do we do?
Our research group focuses on the evolution and paleobiology of marine vertebrates. In some cases, such as with marine tetrapods, these groups have undergone dramatic evolutionary transformations from terrestrial ancestries, with attendant modifications to multiple anatomical, behavioral and ecological systems. These transitions provide a series of evolutionary comparisons that form the basis for understanding how these lineages have diversified in the world's oceans, over geologic time.
Our research group and collaborators include many different stripes of paleobiologists, biomechanists, and geochemists. We are always interested in new perspectives and skill sets! Our work takes us around the world to different museums, research centers, field stations, and, most importantly, field localities. Recent paleontological fieldwork, for example, has included sites near Vancouver Island, British Columbia; the Caribbean coast of Panama; the Atacama Desert of Chile; and the Maryland coast of the Chesapeake Bay. We have received funding for this research from the National Science Foundation, the National Geographic Society, the Natural Sciences and Engineering Research Council of Canada and the Smithsonian Institution.
Principal Investigator:
Nicholas D. Pyenson, Ph.D., Curator of Fossil Marine Mammals
Please see the Paleontological Society's Distinguished Lecturer page for a biography
Nick is curator of fossil marine mammals at the Smithsonian Institution's National Museum of Natural History, in Washington, D.C. Previously, he was a postdoctoral research fellow at the University of British Columbia; he received his Ph.D. from the University of California, Berkeley. He completed his B.S. from Emory University, and his A.A. from Oxford College of Emory University. Nick grew up in both Quebec and Louisiana, which naturally leads to long discourses about the virtues of Stanley Cup parades and crawfish boils. His research spans the systematics, macroecology, taphonomy, and functional morphology of not just marine mammals, but other marine tetrapods, too. Recently, he has been interested in how digital tools can expand fieldwork, outreach and natural history collections all at the same time.

Postdoctoral fellows:
Neil P. Kelley, Ph.D., NMNH Peter Buck Postdoctoral Fellow
Neil just started his NMNH Peter Buck Postdoctoral Fellowship this year, advised by NDP and co-advised by Matt Carrano in Paleobiology. Neil comes to us by way of the University of California, Davis, where he received his Ph.D. in Ryosuke Motani's laboratory, and a B.A. from Oberlin College. Neil will be working on a broad-scale project looking at the macroevolution of marine tetrapods. Marine tetrapods have repeatedly adapted to marine life since the Triassic (e.g., ichthyosaurs, plesiosaurs, whales, seals) and these secondarily marine groups have long been used as textbook examples of macroevolutionary phenomenon such as convergent evolution and adaptive radiation. As a Buck postdoc, he will use the exceptional collections of recent and fossil marine tetrapods at NMNH to explore the tempo and mode of major anatomical transformations that enabled marine tetrapods to repeatedly invade the oceans over the past 250 million years. Neil also has not one but two tattoos that are featured in Carl Zimmer's Science Ink. (Photo: N. P. Kelley).
Maya Yamato, Ph.D., NMNH Peter Buck Postdoctoral Fellow
Maya is a NMNH Peter Buck Postdoctoral Fellow co-advised by Kristofer Helgen in Vertebrate Zoology and NDP in Paleobiology. Maya has a B.A. from Princeton University and finished her Ph.D. recently from Massachusetts Institute of Technology and Woods Hole Oceanographic Institution's Joint Program, where she focused her research on the auditory systems of baleen whales. For her dissertation work, she became proficient at CT scanning whale heads and their ears, along with dissections in the lab or (rotting) on the beach. (She is fearless when it comes to whale guts gore). For her postdoctoral research, she is interested in expanding her species sampling to better model how sound propagates through whale heads -- because we still don't really know how baleen whales hear. When she's not dissecting the latest roadkill or beach pickup in VZ, she keeps us Paleo folk up-to-date on what's happening in the West Wing of the museum. (Photo by D. Hurlbert, NMNH Photography).
Technical Staff and Collections Management:
Holly Little, Digitization and Preservation Specialist
Holly originally hails from North Carolina. She graduated from Duke University in 2010. Through her Visual Studies and Medieval and Renaissance Studies majors she was first exposed to the cutting edge approaches in visualizing historical data. Wanting to explore these concepts further, she enrolled in the University of Michigan School of Information Master's program, studying preservation of information, digitization, and bits of coding, web development, and information access. She came to the Smithsonian by way of the the School of Information's Alternative Spring Break program, and has continued working in the Pyenson Lab (along with the "laser cowboys") through another internship until her recent hire as a digitization and preservation specialist in the Department of Paleobiology at the museum. While working in the lab, she finished her Master's degree at Michigan and expanded her palate by trying the great local seafood in the port town of Caldera, in Chile. (Photo: H. Little).
David J. Bohaska, Museum Specialist in Vertebrate Paleontology
Dave has worked at the Smithsonian since 1989, first as a research assistant and then as part of the collections management team for the Department of Paleobiology at NMNH. Previously, Dave worked at the
Calvert Marine Museum in Solomons, Maryland, as registrar, while also collecting fossil material from the nearby Calvert Cliffs. His love of paleontology started when he collected from the very same cliffs in 7th grade; his knowledge of the collecting history, historiography, paleontology and geology of the Mid Atlantic Coastal Plain is a boon to working with NMNH's fossil vertebrate collections from the region. Dave is also a peerless raconteur of the occasional hijinx and misadventures that color our activities. Dave's lifelong ambition is one day collect a perfect, intact Oligocene whale skull from Onslow Beach. (We're keeping our fingers crossed). It is also an unconfirmed rumor that Dave once was a backup singer for David Hodo in the Village People. (Photo by F. Grady)
Pyenson Lab Alumni:
Jorge Velez-Juarbe, Ph.D. (Currently: Postdoctoral Associate in Vertebrate Paleontology at the Florida Museum of Natural History)
Born in Isabela, Puerto Rico, Jorge first got interested in fossils at the age of eight, and ever since, he wanted to be a paleontologist. Jorge has developed an expertise in the evolution and diversification of sirenians (otherwise known as the group that includes seacows, manatees and dugongs) after collecting fossils of these marine mammals on his 20th birthday. In the summer of 2007, after finishing a bachelor’s degree at the University of Puerto Rico-Mayagüez, he completed a Ph.D. with Daryl Domning in the Department of Anatomy at Howard University in 2012. He was a NMNH pre-doctoral fellow during his time as a research student in the Department of Paleobiology, where he pursued his interests in other groups of marine mammals as well other extinct vertebrates from the Caribbean region. Jorge relaxes to the blues, enjoys cooking and a strong cup of coffee. Find out more about Jorge's latest on his website or on his blog. (Photo by T. Pineda)
Carolina S. Gutstein, Ph.D. (Currently: U-REDES Research Coordinator, Universidad de Chile and Paleosuchus Ltda)
Carolina completed her Ph.D. at the Universidad de Chile, Santiago in 2012. Her dissertation research looked at the morphological and acoustic differences between river and marine dolphins, especially those in South America. She is broadly interested in the functional morphology and phylogeny of toothed whales (Odontoceti), and the paleoenvironments of Neogene coastal systems, including the Bahia Inglesa Formation in the Atacama Region of Chile. Carolina graduated from Universidade Federal de Santa Catarina, in 2003, and she has a Master's degree in geosciences and paleontology from Universidade Federal do Rio Grande do Sul, both in Brazil. In addition to having a knack for giving people great nicknames, she is also committed to promoting paleontology in Chile through the Asociación Paleontológica de Chile, which she recently founded. Follow her updates at her website. (Photo by C. Loch Silva)
Friederike Engel, MSc (Currently: PhD student, University of Groningen)
Fri is from Hamburg, Germany. She studied marine biology at American University in Washington, D.C., from 2007-2011. She worked in the Pyenson Lab during the spring of 2011, focusing on the jaw morphology and variation of some of the earliest fossil pinnipeds in the Emlong collections in Paleobiology at NMNH (which she presented in a poster at the 2011 Secondary Adaptations meeting). She recently completed her Master's in Biological Oceanography, and just and started a PhD in the Center for Ecological and Evolutionary Studies at the University of Groningen, The Netherlands. Fri also played professional soccer in her hometown for Hamburger SV. She has a soft spot for IMAX movies about animals, too. (Photo by Die Torjäger)
