Eszter Posfai, Ph.D.
Assistant professor eposfai@princeton.edu 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. Postdoctoral Research Specialist bwjoyce@princeton.edu 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. Bradley has a broad interest in genetic technologies and is currently working to adapt type-I CRISPR systems for use in genome editing in mammalian systems. Bradley also manages the production of new mouse models for the Posfai lab and other labs at the university and is able to consult on project design as well as undertake mouse model creation. New collaborations are always welcome, so be sure to reach out to him for some expert guidance. 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) rpkim@princeton.edu 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. |
Madeleine Chalifoux
Graduate student, Chemical and Biological Engineering (joint with the Shvartsman lab) mmc7@princeton.edu Maddy received her undergraduate degrees in chemical engineering and French from the University of Illinois. In the Posfai lab, she is interested in using computational tools to understand and map the biomechanical and chemical mechanisms that drive cell fate decisions during the very earliest stages of mammalian embryogenesis. Outside of the lab, she is a lover of traveling and anything outdoors. If given the opportunity, she would love to visit every country in the world, and her superpower would be to speak every language. In her free time she likes to run, cook, and learn new things. |
Ezra Levy
Graduate student, Molecular Biology (joint with the Shvartsman lab) ezral@princeton.edu Ezra holds a B.S. in Biochemistry from Northeastern University, where his research focused on proteomics method development. At Princeton, he plans to study how small systems of cells, such as the germline cyst and pre-implantation embryo, coordinate cell fates using sub-cellular structures. Beyond the lab, he is trying to grow his own vegetables. |
Alana Bernys
Graduate student, Molecular Biology abernys@princeton.edu Alana received her undergraduate degree in molecular biology at Dartmouth College, where she researched sister chromatid cohesion in Drosophila oocytes. In the Posfai Lab, she is interested in studying embryonic growth and the zygotic aspects of the MZT. When not in lab, she can be found doing lots of yoga, trying to keep plants alive, and catching up with her bookclub. |
Yonit Krebs Undergraduate, Molecular Biology ykrebs@princeton.edu Yonit is a molecular biology concentrator in the class of 2024. She hails from Minneapolis, Minnesota. In the Posfai lab, she is currently working on visualizing transcription in live embryos through the MS2-MCP system in mice. In her free time, Yonit enjoys listening to podcasts, hiking, and hammocking. |
Senna Aldoubosh
Undergraduate, Molecular Biology senna.aldoubosh@princeton.edu Senna is a molecular biology concentrator and certificate student in neuroscience in the class of 2025. She grew up in Aurora, CO and attended Eaglecrest High School. In the Posfai Lab, she's interested in uncovering the roles of various proteins involved in the first cell differentiation event in the preimplantation embryo. Outside the lab, Senna is an associate podcast editor at the Daily Princetonian and an ED volunteer at PMC. In her free time, she enjoys long walks, board games, and reading. |
Abhishek Biswas
Senior Research Software Engineer ab50@princeton.edu (609) 258-2059 Abhishek completed his doctoral work at Old Dominion University on developing algorithms for large genomic assemblies using high performance computing machines and worked at Oak Ridge National Laboratory as post-doctoral research associate improving assemblies of complex soil metagenomes. He joined the Research Software Engineering team at Princeton in June 2019. He is working on projects involving development of standard scalable high-performance pipelines for metagenome binning and processing of images generated from various microscopes. Outside work he is listening to audible while walking, cooking, doing chores and sometimes even staring at a wall. |
