Dynamic control of signaling networks in living cells; Rho family and MAPK networks in motility and network plasticity; new tools to study protein activity in living cells (i.e., biosensors, protein photomanipulation, microscopy). Member of the Molecular & Cellular Biophysics Training Program and the Medicinal Chemistry Program. |

During cell shape change and motility, a dynamic cytoskeleton produces the force to initiate plasma membrane protrusion, while vesicle trafficking supplies phospholipids and membrane proteins to the expanding plasma membrane. Extracellular cues activate intracellular signaling pathways to elicit specific cell shape changes and motility responses through coordinated cytoskeletal dynamics and vesicle trafficking. In my lab we are investigating the role of two ubiquitin ligases, TRIM9 and TRIM67, in the cell shape changes that occur during neuronal development. We utilize a variety techniques including high resolution live cell microscopy, gene disruption, mouse models, and biochemistry to understand the complex coordination of cytoskeletal dynamics and membrane trafficking driving neuronal shape change and growth cone motility in primary neurons. |

Our lab is studying the role of mitogen and stress-activated protein kinases to regulate key aspects of cell metabolism. We are also studying signalling by tyrosine kinases in response to toxicological agents or cell stress. |

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 |
As the Director of the UNC Kidney Center, the scope of Dr. Falk’s research interests spans many disciplines, including molecular biology, immunology, genetics, pathology, cell biology, protein chemistry, epidemiology, pharmacokinetics and biostatistics. Dr. Falk is recognized world wide as a leader in research on kidney diseases related to autoimmune responses. He works closely with the basic research scientists within the UNC Kidney Center, including Dr. Gloria Preston, thus this research program provides an environment for Translational Research within the UNC Kidney Center. |

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 |
We study host defense mechanisms in the lungs, particularly the inflammatory and innate immune processes important in the pathogenesis and course of bacterial pneumonia, acute lung injury/acute respiratory distress syndrome, and cigarette smoke-associated lung disease. Basic and translational studies address mechanisms of host defense, including recruitment and function of leukocytes, vascular permeability leading to edema, bacterial clearance and resolution. Cell signaling pathways initiated by binding of leukocyte-endothelial cell adhesion molecules and molecular mechanisms underlying the functions of neutrophils are two particular areas. |

PHD PROGRAM RESEARCH INTEREST |
We study how mammalian cells regulate their survival and death (apoptosis). We have focused our work on identifying unique mechanisms by which these pathways are regulated in neurons, stem cells, and cancer cells. We utilize various techniques to examine this in primary cells as well as in transgenic and knock out mouse models in vivo. Our ultimate goal is to discover novel cell survival and death mediators that can be targeted for therapy in neurodegeneration and cancer. |

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. |
