Christina Bergey - Postdoc
Christina's previous experience included training in both anthropology and computational biology; she uses genomic-scale data to study interactions among gene flow, admixture, natural selection, and behavioral ecology in human and non-human primate populations. She is currently leading our lab's NIH-funded rainforest hunter-gatherer functional and evolutionary genomics projects.
Stephanie Marciniak - POSTDOC
Stephanie recently completed her PhD in Anthropology at McMaster University, where her dissertation research integrated ancient DNA and historical data to study human pathogens and health in antiquity. She is currently directing the ancient DNA laboratory at Penn State and developing archaeogenomic projects focused on reconstructing human population and disease histories.
RICHARD BANKOFF - GRADUATE STUDENT
Richard is interested in lemur evolutionary ecology and the ethics of conservation. Specific areas of focus include dietary and behavioral niche specialization, with an eye towards how these variables can factor into the implementation of conservation efforts that minimize human-lemur resource conflicts. He is currently conducting ethnographic and ecological fieldwork in Madagascar for his dissertation research.
ALEXIS SULLIVAN - GRADUATE STUDENT
Alexis is a Biology graduate student with strong interests in evolution. Her dissertation research is is focused on how human behavior impacts non-human evolutionary biology, including the morphological and evolutionary genomic characterization of size changes in response to human hunting pressures. The introduction chapter of her dissertation chapter has been published as a review article, which you can read to learn more! Alexis also maintains a research blog as part of her website.
DAVID VILLALTA - GRADUATE STUDENT
David joins the lab through the Penn State’s interdisciplinary Ecology program. He has major interests in evolutionary ecology, ecological genomics, and conservation biology. He is currently exploring ideas for bioinformatics research on aye-aye sensory ecology and evolution - including comparative genomics analyses with the striped possum (Dactylopsila trivirgata), a marsupial species sharing many morphological and behavioral convergences with aye-ayes!
Cory Henderson - GRADUATE STUDENT
Department of Biology
Office: Carpenter Building - Room 514
Email: cah422 (at) psu (dot) edu
Cory is a Biology Ph.D. student who is broadly interested in questions regarding the evolutionary relationship between humans and their pathogens. Specifically, he plans to conduct population and functional genomic studies with human head and body lice to address questions about host-parasite coevolution and vector competence.
Monica Guardado - UNDERGRADUATE STUDENT
Monica is interested in the evolution of the human microbiome and the role it plays in human health and disease. She ultimately plans to pursue graduate studies in this area. In the lab, she is working with multiple collaborators including Emily Davenport on a project to study whether chimpanzees acquire functional microbiome components from the termites they consume.
Audrey Arner - UNDERGRADUATE STUDENT
Audrey is a freshman Millennium Scholar interested in human evolutionary genomics. She is first developing the computer science and bioinformatics skillsets necessary for this area of research, and will then be developing and leading an independent project! Audrey was also appointed to Penn State's prestigious, three-year Presidential Leadership Academy.
Co-advised Lab Members:
Ziyu (Raining) Wang - GRADUATE STUDENT
Raining’s primary advisor is George Milner. Raining is interested in paleoepidemiology of infectious disease. Using human skeletal remains from archaeological sites, she intends to incorporate ancient DNA methods to better understand transmission patterns of ancient infectious diseases with the interaction between prehistoric migration, settlement pattern, and environmental changes.
Richard George - GRADUATE STUDENT
Rich is an archaeologist who joins us from Doug Kennet’s Human Paleoecology & Isotope Geochemistry Laboratory (Doug is his primary advisor). Rich is interested in prehistoric population genetics and human behavioral ecology. Specifically, he studies how population dynamics change in response to social and environmental events. Currently he is combining isotopic and ancient DNA analyses to study household dynamics and life history patterns in Mesoamerica.
Diego hernandez - GRADUATE STUDENT
Diego (who is also part of the Shriver lab) is broadly interested in evolutionary and genetic (including admixture and introgression) processes shaping phenotypic variation in anatomically modern humans and Neandertals and Denisovan archaic hominins. He is currently working to identifying regions of the genome introgressed from archaic hominins to modern humans that contribute to morphological variation in facial traits.
Heritiana Randrianatoandro - GRADUATE STUDENT
Department of Paleontology and Biological Anthropology
University of Antananarivo, Madagascar
Our lab is supervising Heritiana’s PhD research -- he is collecting paleogenomic and morphological data to test existing species definitions (and potentially identify cryptic species) within the extinct subfossil lemur genus Archaeolemur. Heritiana’s co-advisors for this project are Laurie Godfrey (University of Massachusetts) and Jeannot Randrianasy (University of Antananarivo). He was recently at Penn State for one year for ancient DNA labwork and dissertation research.
Rindra Rakotoarivony - GRADUATE STUDENT
Department of Paleontology and Biological Anthropology
University of Antananarivo, Madagascar
Our lab is also supervising Rindra’s Malagasy human population genetics PhD project, with University of Antananarivo co-advisors Spiral Germain Jules, Ravelonjanahary Soanorolalao, and Jean Freddy Ranaivoarisoa. Rindra recently collected 200 DNA samples from across the island of Madagascar and recently visited our lab at Penn State for bioinformatics training and population genomic data analysis.
Previous lab members:
Angela's interests include medicine, bioinformatics, and evolutionary biology. While part of our lab, she completed an honors thesis project on a biogeographic (population genetic) analysis of diverse human parasite species to test hypotheses of parasite transfer from archaic hominin to modern human populations.
Abby's interests included the development and application of computational biology methods for studies with immunology and infectious disease components. While a member of our group, Abby worked on bioinformatic analyses of tapeworm genome sequence data and helped conduct functional genomics experiments on the human tapeworm cyst heat response in Peru!
For her honors thesis, Maya led an ancient DNA study of the “Nittany Lion” genome. Mountain lions are now extinct in PA, but Maya is used our clean lab to extract DNA and analyze mitogenomic diversity from the skeletons and skins of 1800s mountain lions from this region. Here is a great PSU news story about Maya and her research.
Jacob's honors thesis research focused on human tropical rainforest hunter-gatherers, using population genomics data to test hypotheses of potential metabolic or thermoregulatory adaptations in these groups related to the common ecological challenges of their habitats (e.g., food limitation, high heat and humidity).
2013-2015: Graduate student (Anthropology)
Stephen's interests include human evolutionary medicine, health, and disease. While in the lab he studied tapeworm biology and functional genomics as a proxy for the evolution of hominin meat eating and food cooking behaviors. He is currently pursuing a health professional career.
While a member of our group, Adrijana led a bioinformatics study to test hypotheses of adaptive evolution related to human dietary history, facial shape changes, and dental variation. She has major interests in human genetics and public health and is currently pursuing a career in genetic counseling.

Currently: Curator (Assistant Professor), Department of Anthropology, Smithsonian National Museum of Natural History
While a postdoc in our laboratory, Logan focused on paleogenomic projects including mitochondrial and nuclear genome analyses of Madagascar’s extinct subfossil lemurs. He also studied the ecological history of wild New World plants related to pumpkins and squashes, including how these populations may have been affected by the extinctions of megafaunal mammals, their natural seed dispersers.
2011-2014: Undergraduate (Anthropology and Community, Environment, and Development; Schreyer Honors College)
Currently: PhD student, Stony Brook University - Department of Anthropology
For her honors thesis, Kate compared aye-aye food resource availability vs. foraging behavior (with a field-based study in Madagascar) to help understand why the home ranges for individuals of this endangered species are so huge. Here is a nice PSU article about Kate and her thesis research.
2012-2013: Postdoctoral fellow (Anthropology)
Currently: Lecturer (Assistant Professor), Imperial College London - Department of Life Sciences
Jason studied human evolution and population history, especially the fate of evolutionarily advantageous alleles in admixed populations, including among the Malagasy, the people of Madagascar.
