Over the years, scientists have been generating vast amounts of biological data using a variety of laboratory techniques such as microarrays, RNA interference, and yeast two-hybrid (a process that uses yeast to discover how proteins interact with each other). As these mountains of data build, it's essential that scientists find powerful ways to cross-reference them. Ge is developing computational methods that amalgamate various data sets, work that one day will greatly accelerate the speed with which researchers identify the functions of genes and proteins. (To date, fewer than half of mammalian genes have a known function.)
So far, Ge has been using these computational methods to test biological data from the earthworm C. elegans, one of the most well-characterized animal models. She also works with these animal models in a "wet lab" in order to test and tune the accuracy of her analyses. Ge has already used this combination of tools to discover the function of certain proteins essential for early embryogenesis in C. elegans.
In her graduate work, she and her colleagues devised a way to examine how certain protein interactions are conserved across evolution. The team showed that conservation of these interactions among yeast and worms was surprisingly high.
Currently, she is focusing on building integrated approaches to help researchers understand biological processes on a system-wide level (a field of research known as systems biology), and applying these approaches to specific questions regarding embryonic development of the C. elegans.
A native of China, Ge came to the U.S. in 1999 when she was selected for a Fu Fellowship, which supports Chinese students studying at Harvard. Ge worked in Marc Vidal's lab at the Dana Farber Cancer Institute, where she earned her PhD in 2004.
