Principal Investigator

Michael D. Purugganan

Michael D. Purugganan Michael obtained his undergraduate degree in chemistry at the University of the Philippines in 1985. He began his graduate work at Columbia in empirical and theoretical biophysical chemistry, obtaining an MA before moving to the University of Georgia where he got a Ph.D. in Botany (minor in Global Policy Studies) in 1993. After a two year Alfred P. Sloan Foundation postdoctoral fellowship at the University of California at San Diego, he joined the faculty at NC State. He was promoted to associate professor in 2001. In 2005, he became a William Neal Reynolds Professor of Genetics and elected a Fellow of the American Association for the Advancement of Science (AAAS). Michael's research interests include the molecular evolution and ecology of development, the nature of adaptation at the molecular level, and the evolutionary genetics of plant domestication. He seems to be distressingly fond of black clothing, preferably Armani.

Postdoctoral Fellows

Megan Hall

Megan Hall Megan did her undergraduate work in Biology at University of California, Santa Cruz, where as a fighting banana slug, she also played volleyball and was a collegiate national champion in ultimate frisbee. She became inspired to be an evolutionary biologist while studying endangered Hawaiian honeycreepers on the slopes of Haleakala and Mauna Kea. She then began graduate school at the University of Oregon working with John Willis on the genetics of adaptation in annual and perennial Mimulus guttatus. John moved to Duke University midway through Megan’s dissertation project, and so Megan was forced to leave fair Oregon for Durham, where she completed her PhD in 2005. She is now studying the molecular population genetics of flowering time in Arabidopsis thaliana.

Yoshie Hanzawa

Yoshie Hanzawa Yoshie graduated in plant molecular genetics from the University of Hokkaido in Japan in 2000. During her one-year post-doc experience in Japan, she found her new potential in the world and worked with George Coupland at the John Innes Centre in the United Kingdom. Shortly thereafter, she joined the Desmond Bradley lab at the John Innes Centre and worked on inflorescence development in Arabidopsis and Snapdragon. Following the message of a fortune cookie, she's decided on her current move, this time to the USA in 2006, and is betting her future success as a scientist on the Purugganan lab.

Kristie Mather

Kristie Mather Kristie's undergraduate degree in Biochemistry is from Beloit College in Wisconsin. After two summers in Carole Ober's HLA genetics lab at the University of Chicago, she decided that evolutionary genetics was much more exciting. For graduate school, she joined Glenys Thomson's lab at the University of California at Berkeley. Her thesis work is on long distance linkage disequilibrium in four human populations using microsatellites in six regions of the genome. After receiving her PhD in Integrative Biology in 2004, she joined the Purugganan lab. At NC State, she's working on the rice genome project and some ongoing collaborations on the population genetics of HLA genes.

Christina Richards

Christina Richards Christina completed her undergraduate degree in Biology at Swarthmore College in Swarthmore, PA. After an internship with Steve Pennings at the Univeristy of Georgia Marine Institute on Sapelo Island and working as a research technician for Sonia Sultan at Wesleyan University, she started doctoral work in salt marsh plant eco-physiology and genetics. She received her Ph.D. in 2004 from the University of Georgia working with Lisa Donovan and Rodney Mauricio and moved on to work on ecological genetics and epigenetics of the invasive Japanese knotweed with Massimo Pigliucci at Stony Brook University in New York. Here in the Purugganan lab, she will study epigenetic effects and microarray analyses of gene expression in wild Arabidopsis populations. When she's not in the lab, she's rowing with the NY Athletic Club in Westchester County.

Samara Rubinstein

Samara Rubinstein Samara got her B.A. in Anthropology from Tulane University in New Orleans in 1998 and her Ph.D. in Molecular Anthropology from Temple University in Philadelphia in January 2007. In the Laboratory of Molecular Anthropology at the University of Pennsylvania, she conducted numerous research projects on human population genetics, including the mtDNA diversity of Slavic populations, which formed the basis of her dissertation. As a Postdoctoral Researcher in the PuruggananŐs Laboratory at NYU, she is managing a project that seeks to understand the evolutionary genomics of rice domestication.

Xianfa Xie

Xianfa Xie Xianfa tries to understand every aspect of life. He obtained his undergraduate degree in microbiological engineering from Shandong University in China and then, fascinated by evolution, went on to study the evolutionary and ecological genetics of insects at the Chinese Academy of Sciences. After he obtained a master degree in ecology and evolution at SUNY-Stony Brook, he worked with Jeffrey Feder at the University of Notre Dame to study the speciation of a model system, the maggot fly (Rhagoletis pomonella) species complex. He joined the Purugganan lab as a postdoc in August 2005 and is currently studying the evolutionary genomics of rice (Oryza sativa) associated with its domestication as well as the role of epigenetics in genomic evolution. When he is not studying science in laboratory or library, he probably is doing some natural or cultural exploration and taking all kinds of pictures somewhere.

Graduate Students

Jennifer Cork

Jennifer M. Cork Jeni graduated from Western Kentucky University with a B.S. degree in recombinant genetics in 2001. Her undergraduate honors thesis was on the evaluation of Type I error rates in tests for geographic heterogeneity from microsatellite data. In addition, she worked on a project to determine the structure of Kentucky's whitetail deer population. Her research interest is focused on molecular evolution, and her current project is the identification and analysis of rapidly evolving genes in Arabidopsis thaliana. Jeni also has a special talent for freezing lab computers and accidentally killing once healthy plants.

Ian Ehrenreich

Ian Ehrenreich Ian completed his BA in Human Biology at Stanford University in 2002. His undergraduate honors project with Brendan Bohannan explored the ecology and evolution of triclosan-resistant Escherichia coli. After graduating, Ian worked first as a technician in Ward Watt's lab at Stanford University studying biochemical adaptation in Colias butterflies, and then as a guest investigator at the Woods Hole Oceanographic Institution in the labs of John Waterbury and Eric Webb focusing on the molecular ecology of diverse cyanobacteria. Ian is a Gaann fellow and an NSF predoctoral fellow. He is currently researching the evolution of shoot architecture in Arabidopsis thaliana and he hopes to figure out why exactly variation in this trait exists. Until that unlikely time, it is appropriate that Ian is a student of the Wolfpack as he is referred to by many as the Wolfman.

Technicians

Angela Stathos

Angela Stathos Angela graduated from the University of Chicago in 2007 with a BA in Biological Sciences and specialization in Genetics. In Chicago, she worked under Joy Bergelson, studying variation in presence/absence of two resistance genes found in local populations of Arabidopsis thaliana. Now she finds herself in New York City, trying to figure out what this place is all about, while working in the Purugganan lab. Angela is contemplating graduate school, where she would like to study ecology, yet seems to find herself inevitably bonded to molecular biology. When not devoting her life to the study of model plant systems, Angela is likely to be found trekking the city, foraging, or lying around her apartment listening to music. She also aspires to climb rocks, take pictures, and generally acquire new hobbies.
