We focus on the translational potential and clinical impact of biomedical research. Our general research interest is to reveal the mechanisms of eye diseases using animal and other research models. One current project is to investigate the markers of limbal stem cells using transgenic mice. The lack of limbal stem cell marker has been a long-term bottleneck in the diagnosis and treatment of limbal stem cell deficiency, which leads to a loss of corneal epithelial integrity and damaged limbal barrier functions with the symptoms of persistent corneal epithelial defects, pain, and blurred vision. The research results will directly impact on the early-stage diagnosis of the disease and the quality control of ex vivo expanded limbal stem cells for transplantation. |

We aim to dissect the epigenetic and transcriptional mechanisms that shape T cell lineage specification during development in the thymus and in the periphery upon antigen (microbial, viral) encounter. Aberrant expression of transcription and epigenetic factors can result in inflammation, autoimmunity or cancer. We are using gene deficient mouse models, multiparameter Flow Cytometry, molecular biology assays and next generation sequencing technologies to elucidate the regulatory information in cells of interest (transcriptome, epigenome, transcription factor occupancy). |

Modern Technologies from next-gen sequencing to high resolution imaging have advanced our knowledge of kidney development, function, and disease. We are among the pioneers utilizing techniques such as CHIP-seq, RNA-seq, modern genome editing, and imaging to understand how regulatory programs control progenitor populations during kidney development. Our goal is to understand how these programs contribute to progenitor specification and maintenance, and how they are altered during disease and aging. Our ultimate goal is translational applications of our research to develop new therapeutics and regenerative strategies. |

My research focus pertains to vascular remodeling as it relates to the pathogenesis and progression of thoracic aortic aneurysms. Using murine and porcine models, as well as human aneurysm tissue samples, we study proteinase and signaling biology with a view towards defining novel modalities targets for diagnosis, tracking, risk stratification and non-surgical treatment of this devastating disease. |

Flexibility of the brain allows the same sensory cue to have very different meaning to the animal depending on past experience (i.e. learning and memory) or current context. Our goal is to understand this process at the levels of synaptic plasticity, neural circuit and behavior. Our model system is a simple brain of the fruit fly, Drosophila. We employ in vivo electrophysiology and two-photon calcium imaging together with genetic circuit manipulation. Taking advantage of this unique combination, we aim to find important circuit principles that are shared with vertebrate systems.

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. |

Congenital heart diseases are one of the most common birth defects in humans, and these arise from developmental defects during embryogenesis. Many of these diseases have a genetic component, but they might also be affected by environmental factors such as mechanical forces. The Liu Lab combines genetics, molecular and cell biology to study cardiac development and function, focusing on the molecular mechanisms that link mechanical forces and genetic factors to the morphogenesis of the heart. Our studies using zebrafish as a model system serve as the basic foundation to address the key questions in cardiac development and function, and could provide novel therapeutic interventions for cardiac diseases. |

PHD PROGRAM RESEARCH INTEREST |
A critical component of airways innate defense is the thin liquid layer lining airway surfaces, the periciliary liquid (PCL), that provides a low viscosity solution for ciliary beating and acts a lubricant layer for mucus transport. Normal airways appear to be able to sense the PCL volume and adjust ion channel activity accordingly. The long term goal of this laboratory is to understand how homeostasis of PCL volume occurs in airway epithelia under normal and pathophysiological conditions. Currently, research in the Tarran lab is focused on three main areas: 1) Regulation of epithelial cell function by the extracellular environment, 2) Gender differences in cystic fibrosis lung disease and 3) The effects of cigarette smoke on epithelial airway ion transport. We utilize cell biological and biochemical techniques coupled with in vivo translational approaches to address these questions. |

PHD PROGRAM RESEARCH INTEREST |
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. |
