PHD PROGRAM RESEARCH INTEREST |
My research interest is in genomic characterization and integrative genomic approaches to better understand cancer. My group is part of the NCI Genome Data Analysis Center focused on RNA expression analysis. We have a number of ongoing projects including developing molecular classifications for potential clinical utility, developing methods for deconvolution to understand bulk tissue heterogeneity, analysis of driver negative cancers, and analysis of ancestry markers with cancer features. |

Interest areas: Developmental Biology, Cell Biology, Cancer Biology, Stem Cells, Genetics PhD programs: Pathobiology & Translational Sciences, Genetics & Molecular Biology, Cell Biology & Physiology, Oral Biology, Biology Tissue development and homeostasis depend on the precise coordination of self-renewal and differentiation programs. A critical point of regulation of this balance is at the level of cell division. In the Williams lab, we are interested in stratified epithelial development, stem cells, and cancer, with a particular interest in how oriented cell divisions contribute to these processes. Asymmetric cell divisions maintain a stable pool of stem cells that can be used to sustain tissue growth, or mobilized in response to injury. However, dysregulation of this machinery can lead to cancer, particularly in epithelia where tissue turnover is rapid and continuous. Using the mouse epidermis and oral epithelia as model systems, we utilize cell biological, developmental and genetic approaches to study the molecular control of oriented cell divisions and mitotic spindle positioning, and how division orientation impacts cell fate choices in development, homeostasis, injury, and disease. |

With an emphasis on chromatin biology and cancer epigenetics, our group focuses on mechanistic understandings of how chemical modifications of chromatin define distinct patterns of human genome, control gene expression, and regulate cell proliferation versus differentiation during development, and how their deregulations lead to oncogenesis. Multiple on-going projects employ modern biological technologies to: 1) biochemically isolate and characterize novel factors that bind to histone methylation on chromatin, 2) examine the role of epigenetic factors (chromatin-modifying enzymes and chromatin-associated factors) during development and tumorigenesis using mouse knockout models, 3) analyze epigenomic and transcriptome alternation in cancer versus normal cells utilizing next-generation sequencing technologies, 4) identify novel oncogenic or tumor suppressor genes associated with leukemia and lymphoma using shRNA library-based screening. We are also working together with UNC Center of Drug Discovery to develop small-molecule inhibitors for chromatin-associated factors as novel targeted cancer therapies. |

We are interested in basic DNA-protein interactions as related to – DNA replication, DNA repair and telomere function. We utilize a combination of state of the art molecular and biochemical methods together with high resolution electron microscopes. |

PHD PROGRAM RESEARCH INTEREST |
We address fundamental issues in cell and developmental biology, issues such as how cells move to specific positions, how the orientations of cell divisions are determined, how the mitotic spindle is positioned in cells, and how cells respond to cell signaling – for example Wnt signaling, which is important in development and in cancer biology. We are committed to applying whatever methods are required to answer important questions. As a result, we use diverse methods, including methods of cell biology, developmental biology, forward and reverse genetics including RNAi, biochemistry, biophysics, mathematical and computational modeling and simulations, molecular biology, and live microscopy of cells and of the dynamic components of the cytoskeleton – microfilaments, microtubules, and motor proteins. Most experiments in the lab use C. elegans embryos, and we have also used Drosophila and Xenopus recently. C. elegans is valuable as a model system because of the possibility of combining the diverse techniques above to answer a wide array of interesting questions. We also have a long-term project to develop a new model system for studying how biological materials can survive extremes, using little-studied organisms called tardigrades. Rotating graduate students learn to master existing techniques, and students who join the lab typically grow their rotation projects into larger, long term projects, and/or develop creative, new projects. |

PHD PROGRAM RESEARCH INTEREST |
Our lab applies cutting edge genetic and proteomic technologies to unravel dynamic signaling networks involved in cell proliferation, genome stability and cancer. These powerful technologies are used to systematically interrogate the ubiquitin proteasome system (UPS), and allow us to gain a systems level understanding of the cell at unparalleled depth. We are focused on UPS signaling in cell cycle progression and genome stability, since these pathways are universally perturbed in cancer. |

PHD PROGRAM RESEARCH INTEREST |
My lab studies how cell proliferation is controlled during animal development, with a focus on the genetic and epigenetic mechanisms that regulate DNA replication and gene expression throughout the cell cycle. Many of the genes and signaling pathways that we study are frequently mutated in human cancers. Our current research efforts are divided into three areas: 1) Plasticity of cell cycle control during development 2) Histone mRNA biosynthesis and nuclear body function 3) Epigenetic control of genome replication and function. |

PHD PROGRAM RESEARCH INTEREST |
Our lab tries to understand viral pathogenesis. To do so, we work with two very different viruses – West Nile Virus (WNV) and Kaposi¹s sarcoma-associated herpesvirus (KSHV/HHV-8). |

PHD PROGRAM RESEARCH INTEREST |
Our research centers on understanding the molecular basis of human carcinogenesis. In particular, a major focus of our studies is the Ras oncogene and Ras-mediated signal transduction. The goals of our studies include the delineation of the complex components of Ras signaling and the development of anti-Ras inhibitors for cancer treatment. Another major focus of our studies involves our validation of the involvement of Ras-related small GTPases (e.g., Ral, Rho) in cancer. We utilize a broad spectrum of technical approaches that include cell culture and mouse models, C. elegans, protein crystallography, microarray gene expression or proteomics analyses, and clinical trial analyses. |
