Research Interests:
My lab is broadly interested in how growth factors such as PDGF regulate cell growth. We are currently focused on developing new therapies for the adult brain tumor glioblastoma using cancer stem cells.. For several years we have been working on how the c-fos promoter is regulated. We discovered a growth factor inducible called SIF which turns out to be composed of STAT family transcription factors. We are currently interested in the role of STAT3 in cancer and in cancer stem cells in particular. We have been studying this primarily in the context of the glioblastoma brain cancer. The graphic at the top of the page shows cancer stem cells from a human glioblastoma growing as neurospheres on the left and stained with stem cell and neural markers. Another interest of the lab is the development of an annotated database of genes called MedStract in collaboration with a computational linguistics group at Brandeis. We are currently working on a DARPA project called "Communicating with Computers" to allow biologists to use natural language to discuss molecular pathways. Think of an enhanced Siri for the Cell. We have also pioneered the use of a human near haploid cell line for somatic cell genetics.
