Eszter Posfai, Ph.D.
Eszter received her M.S. degree in Molecular Biology and Genetics from the University of Szeged in Hungary and her Ph.D. in Genetics from the University of Basel in Switzerland. Intrigued by the earliest events of mammalian development, during her Ph.D. she studied the role of epigenetic mechanisms in the germ line and how they impact the development of the next generation. For her postdoctoral work she joined the lab of Dr. Janet Rossant at the Hospital for Sick Children in Toronto, Canada and explored how the earliest cell fate decision is made in the mouse embryo. She also co-developed a new CRISPR/Cas9-based editing method to generate genetic tools to query these processes at a single cell resolution. Her current research at Princeton University focuses on understanding the dynamics of molecular and cellular events underlying early embryonic development.
Bradley Joyce, Ph.D.
Research Specialist, Lab Manager, Go-to guru and all-round Mr nice guy
Bradley received a Ph.D. in Anatomy, Physiology and Genetics from Oxford at the Laboratory of Prof. Shankar Srinivas studying the molecular mechanisms of AVE cell migration. Brad then moved to the US to undertake a postdoctoral research position with Dr Danelle Devenport to study planar cell polarity in the skin and the control of hair follicle morphogenesis. In his spare time Brad enjoys spending time outdoors, DIY around the home and coaching judo at the Princeton YMCA.
Rebecca Kim-Yip, Ph.D.
Postdoctoral fellow (joint with the Toettcher lab)
Rebecca received her PhD from the University of California, San Francisco. She is broadly interested in how isogenic populations of cells acquire heterogeneous patterns of fate during development and the signaling pathways that control this process. In collaboration with the Toettcher Lab, Rebecca is using optogenetics to probe the signaling dynamics during cell fate acquisition in the early mouse embryo. Outside of the lab she enjoys discussions about model organisms, knitting and playing her violin.
Visiting Master's student
I did my Bachelors at the University of Konstanz in Germany, studying the role of BMP signalling in caudal fin development. In the Posfai lab I am studying the dynamics of cell fate decisions in the early mouse embryo. I’m also an active member of the student council at the University of Konstanz and in my free time I like to go cycling, hiking and windsurfing.
