Researchers Develop Improved Method to Visualize Biologic Molecules

PLoS Press Release for our first paper on mRNA quantification in whole embryos.

“How are biologic molecules arranged inside the embryo so that embryonic development occurs reliably every time? Princeton researchers, led by Thomas Gregor, an assistant professor of physics and the Lewis-Sigler Institute for Integrative Genomics, and Shawn Little, a postdoctoral fellow in the laboratory of Professor Eric Wieschaus in the Department of Molecular Biology, have developed a new method to better understand how an embryo’s basic molecular makeup helps ensure that the embryo’s development occurs reliably every time. The results of this research into the fruit fly Drosophila introduce a method for making precise measurements of biologic units (so-called mRNA molecules) that play a key role in development. The findings are published in the March 1st issue of  in the online, open access journal PLoS Biology.”

Postdoctoral position available

Even if people can always apply by simply sending me an email, for the next two months I am actually officially looking to fill a postdoctoral position, primarily to work on the fly embryogenesis project. It would make some administrators at Princeton really happy if you could go through this site and follow instructions from there. Please be sure to clearly state why you would be interested in joining the lab.
