PHD PROGRAM RESEARCH INTEREST |
We are interested in elucidating context-specific functions of products from single long noncoding RNA (lncRNA) loci. Since lncRNAs have been implicated in many cellular processes, it is critical to delineate specific roles for each lncRNA. Moreover, as they are increasingly associated with diseases including developmental disorders, degenerative diseases, and cancers, defining their functions will be an important precursor to their use as diagnostics and therapeutics. We specialize in adopting -omics approaches including genomics, transcriptomics and proteomics, combined with single molecule methods to study the intermolecular interactions – RNA-protein, RNA-RNA and RNA-chromatin that lncRNAs use to execute their functions in normal stem cells and cancer. |

Our lab uses human genetics to identify new mechanisms driving coronary artery disease (CAD). Starting with findings from genome-wide association studies (GWAS) of CAD, we identify the causal gene at a given locus, study the effect of this gene on cellular and vessel wall biology, and finally determine the molecular pathways by which this gene influences CAD risk. Within this framework, we use complex genetic mouse models and human vascular samples, single-cell transcriptomics/epigenomics and high-throughput CRISPR perturbations, as well as traditional molecular biology techniques. |

The broad goal of our research is to understand basic mechanisms regulating erythropoiesis (red blood cell differentiation and maturation). Our current work focuses on a family of dual functional proteins (poly C binding proteins) which both regulate RNA processing and chaperone iron within cells. Using biochemical, cellular, and in vivo models we explore the cross talk between iron trafficking and RNA regulation mediated by poly C binding proteins and how these activities are modulated by disease. |

In my lab, we are exploring the roles that kinases play in neurodegeneration through the creation of high-quality, small molecule tools. Our team designs, synthesizes, and evaluates small molecules capable of kinase modulation, sometimes targeting kinase inhibition and sometimes kinase activation. In order to accomplish our aims, we work closely with X-ray crystallographers within the larger SGC and with biologists, including experts in using stem cells to model neurodegenerative diseases. We seek enthusiastic students with an interest in neuroscience who are willing to learn and apply techniques that span chemistry and biology to better understand and address neurodegeneration. |

PHD PROGRAM RESEARCH INTEREST |
I am a Pediatric Pulmonologist. My lab studies cell phenotype regulation in the context of lung fibrosis and lung development. We use in vitro and ex vivo models, mouse models, human tissue, and multi-omic approaches to explore fibroblast phenotypes in the formation of lung alveoli and in the pathologic modeling of lung fibrosis, and explore novel therapies for lung disease.

My research interests are focused on mechanisms associated with altered innate immune functions, which lead to dysregulated adaptive immunity. Currently my research program has three major arms integrated through with a central philosophy. Specifically, our laboratory focuses on the contribution of epithelial cell biology and signaling to innate and adaptive immune homeostasis and dysfunction. We study the contribution of what I term ‘epithelial cell innate immune (dys)function’ to three major disease conditions: pancreatic cancer, type 1 diabetes (autoimmunity), and periodontal disease (autoinflammation). While appearing to be a diverse research program, we have found that many of the mechanisms and systems in play are surprisingly (or maybe not so surprisingly) similar allowing for rapid translation of our findings. Importantly, previous investigations into the role of epithelial cells in immunobiology have been hindered by a lack of robust primary cell culture techniques, which our laboratory has been able to overcome using both animal and human tissues. Thus, using our novel and unique tools we are able to evaluate our findings in the human conditions, again making translation of our findings that much more feasible. In addition to my primary research objectives, my collaborative research programs, have allowed me to be involved, at some level, in investigating the basic biology of health, multiple autoimmune conditions, autoinflammation, sepsis, and exercise induced inflammation I have been blessed with the opportunities to couple my passions and expertise with that of others to bring together multiple research communities with the goal of advancing human health and hope to be able to continue to do so for years to come. |

We study the molecular mechanisms of HIV latency. Transcriptional silencing of HIV is a key mechanism of persistence in patients, and is a barrier to viral eradication, but little is known about the latent reservoir or the molecular mechanisms that regulate it. As such, our repertoire of drugs for targeting latently infected cells is limited. Some latency reversing agents (LRAs) have been developed, but these are typically reactivate only a minor subset of proviruses. This inefficiency is in part due to the reservoir not constituting a uniform target, but instead being a heterogeneous set of cells with diverse characteristics and restrictions to HIV expression. However, most analyses of latency use bulk cell cultures assays in which crucial information about the behavior of individual cells is lost. Also, latently infected cells in patient samples are exceedingly rare, making them very difficult to study directly. New technological breakthroughs in the field of single cell analysis as well as the development of primary cell models for HIV latency now open the possibility of observing how latently infected cells form and are maintained at single cell resolution. Our lab has developed tools to study the establishment, maintenance and reversal of HIV latency at single cell resolution using multi-omics methods. Furthermore, we combine these approaches with genetic perturbation, time-lapse microscopy and novel bioengineering tools to gain insight into how the host cell regulates HIV latency. We have recently discovered using single cell RNAseq (scRNAseq) that latency in primary CD4 T cells is associated with expression of a distinct transcriptional signature (Bradley et al 2018). Our hypothesis is that this signature represents part of a cellular program that regulates latency, and that this program is an exciting novel target for the development of LRAs. Ongoing projects in the lab involve the application of new technologies to our model systems, and testing/validation of the roles of host cell pathways we have identified in HIV latency. Our overall goal is to identify new targets for the development of drugs to clear the HIV reservoir. |

PHD PROGRAM RESEARCH INTEREST |
We are studying tissue integrity and repair to develop innovative approaches for regenerative medicine and cancer prevention. We concentrate on highly regenerative (endometrial and intestinal) tissues and are particularly interested in how persistent inflammation influences the breakdown of biochemical pathways that oversee genome stability, stem cell plasticity, and cell adhesions and how these events influence future tissue repair and onset of disease, such as cancer. Projects employ a variety of molecular, cellular, biochemical, genetic, and machine learning techniques that span across cell culture systems, genetically engineered mouse models, and human tissues to understand the impact of acute and chronic inflammation on cell division, cytoskeletal dynamics, and DNA repair in regenerating epithelial cells. |

PHD PROGRAM RESEARCH INTEREST |
The Gladden lab studies how cell adhesion and cell polarity are intertwined in normal tissue development and how these pathways are altered in diseases such as cancer. We use a combination of 3D cell culture, mouse models and protein biochemistry to study how cell polarity and adhesion regulate tissue organization. Our work focuses on the interplay between cell adhesion and cell polarity proteins at the adherens junction and how these proteins regulate tissue organization. We concentrate on the development of the endometrium epithelium in the female reproductive tract and the cell biology of endometrial cancer. |
