Mason Youngblood

Mason joins the Psychology PhD program, and our lab, this coming Fall. He is interested in social learning, vocal development, and cultural evolution. He also plans to work with Ofer Tchernichovski at Hunter College, CUNY.


M. Aaron Owen

Aaron received a BS in Biology from Northern Illinois University in 2008, where he worked on parasitoid wasp mating behavior in Bethia King's lab. He moved on to his Master's work on mate choice in zebrafish in Rick Howard's lab at Purdue University, receiving his degree in 2010. He is a behavioral ecologist interested in sexual selection, particularly in the evolution of mating preferences. He is currently jumping from field season to field season studying sexual selection and social behavior in the small Indian mongoose (Herpestes auropunctatus).

Chenghui Ju

House finches exhibit vast geographic variation in song composition and syllable types. Chenghui's major research goal is to design a computational approach to study the song structure of the house finch, in order to facilitate the comparison of patterns of song variation among populations over time and space. Chenghui is broadly interested in cultural evolution and the divergence of learned traits such as bird song and human language. Before coming to the lab she worked on cephalopod behavior and cognition with Jenny Basil at Brooklyn College. In July 2015 she defended her dissertation, and is now spending an extra term in our lab finishing and applying her original acoustic analysis software package, FinchCatcher.

Franny Geller

Franny Geller

Having graduated with a bachelors degree in Music from QC, Franny is making the transition from human song to birdsong to biology. Since joining the lab, she has developed materials for an Ethiopian Virtual Herbarium and implemented a new method of quantifying the appearance of bird eggs. Her main current research aims at discovering the developmental, demographic, and ecological fractors that underlie house finch song structure and cultural transmission.

Masters/Postbaccalaureate researchers

Wendy Perez

Wendy Castillo

Wendy is recording and analyzing geographic variation in house finch songs in Hawaii, building on the mainland datasets of Paul Mundinger (1982) and Jackie Song (2012), and comparing how songs change upon introduction to multiple new locations.

Khaleda Khan

Khaleda studies the behavior of African Ploceus weaverbirds. For her honors undergraduate thesis she compared the degree to which male village weavers (Ploceus cucullatus) spend time on survival vs. reproductive behaviors at a study site in Ethiopia. Her Master's project aims at comparing the pattern of cultural (song) divergence to genetic divergence among species of genus Ploceus. Khaleda is our lab manager.

Jacqueline Milander

Jacqueline is studying the song of the Northern Mockingbird (Mimus polyglottos). This bird not only learns from other members of its species but also mimics other sounds. Jacqueline is determining how the ambient sounds in particular local areas influence what a bird learns and sings.

Lizbeth Vazquez

Liz is our lab nurse. She also helps out with various projects in the lab, especially looking for birds and contributing to the Online Bibliography of Environmental Thought.

Eric Roginek

Eric is broadly interested in behavioral mechanisms, and comes to us with a background in psychology. He is currently analyzing house finch song variation in California in order to track cultural evolution.


Sara Paccione

Sara, a Master's student in English, is interested in J. R. R. Tolkien and children's literature. She is performing background research for several classic works of literature covered in the Reflections on Great Literature blog.

Undergraduate researchers

Postdoctoral researcher

Andrew F. Richards

Andy received his PhD from the University of Michigan for his study of the life history and behavior of female bottlenose dolphins in Shark Bay, Australia. Since then he worked for many years with Richard D. Alexander, focusing on the evolution of human behavior, physiology, psychology and culture. Currently he continues this investigation into evolutionary explanations for human traits, and is also designing new projects in learned vocal communication and cultural change.


The students below have contributed to our research projects in the lab, and most of them have achieved undergraduate or graduate degrees in the process; several other students not included here have worked in the lab over the years as well, as visiting researchers, trainees or assistants.

Elliot Aguilar (2009-2015; PhD., Ecology, Evolution and Behavior, 2015)

Elliot was our lab's first doctoral student. He defended his dissertation, Models and Methods in Social and Cultural Evolution, in June 2015. He is now has a postdoctoral research fellowship at the University of Pennsylvania, where he is working in the laboratory of Erol Akçay.

Abudoula Nulumu, House finch cultural evolution. Abudoula also developed a mobile quiz game app for the lab and continues to collaborate with us on its development.

Johanna NavarroJohanna Navarro (2009-2015; MA, Biology, 2015)

Johanna was our lab's first Master's student. She performed and published experimental tests on the effect of light on bird egg color, and also conducted a comparative study of the evolution of egg color in ratites.

Seema was one of our first three lab members (along with Stephanie and Khaleda). She studied original reports of local uses of woody plants in The Gambia in West Africa, and discovered several local medicinal uses that had not yet been documented.

Stephanie Kandasami (2009-2014; BA in Biology, and Honors Thesis, 2011)

Stephanie, one of our first three lab members (along with Seema and Khaleda), studied the divergence of moral codes between West African cultures, a daunting long-term project she began and led for five years, and that continues in our lab. Steph is now in the Master's of Public Health program at Columbia University.
