PHD PROGRAM RESEARCH INTEREST |
Our overarching goal is to delineate how cells respond to cancer therapeutics that induce DNA damage, and, accordingly, to develop new strategies that overcome treatment resistance in cancer, including head and neck cancer. To achieve this goal, we study new mechanisms of the cell cycle and DNA repair using comprehensive experimental systems; we investigate the involvement of these mechanisms in oral cancer progression and resistance; and we develop new therapeutics using cellular, biochemical, and pharmacological approaches. |

PHD PROGRAM RESEARCH INTEREST |
Fundamentally, our research is focused on how the nervous and immune systems are developmentally educated by infectious and non-infectious stressors across the “gum-to-gut” axis. One current major focus of the lab is to elucidate how early life stress impacts the developing gut and dentition using zebrafish as an ideal — and translational — model organism. We utilize a combination of advanced imaging, next-generation sequencing, and genetic approaches to achieve a greater understanding of how early life events dictate health outcomes across the lifespan and generations. In addition to these primary research interests, we maintain active collaborations with other groups within the Adams School of Dentistry and across campus. |

PHD PROGRAM RESEARCH INTEREST |
Dr. Divaris has diverse research interests and a portfolio interrogating both proximal and distal determinants of oral health and disease, ranging from genomics of oral health traits and behavioral sciences to health disparities and dental education. The core data-generating work is carried our via NIH grants U01-DE025046 (ZOE 2.0 study, “Genome-wide association study of early childhood caries”) and P01HD103133-02S2 (Pediatric HIV/AIDS Cohort Study (PHACS); Biofilm multi-omics in the AMPU UP cohort-research supplement). I am a pediatric dentist with doctoral and postdoctoral training in oral and genetic epidemiology and interests in biological determinants of oral health and disease. |

PHD PROGRAM RESEARCH INTEREST |
The Jacox Lab aims to improve patient care and outcomes in oral health. This goal takes shape via several tracks of interdisciplinary human studies: -A primary focus of the lab has been on outcomes of jaw surgery patients, who suffer from Dentofacial Disharmonies (DFD). Patients with DFD have severe skeletal disproportions with underbites or open bites, necessitating orthodontics and jaw surgery for full correction. Roughly 80% of our patients with DFD exhibit speech distortions, compared to 5% of the general population, which negatively impact their self-confidence and quality of life. Despite patients pursuing invasive surgery, it is unknown whether jaw surgery is palliative for articulation errors. We are using ultrasound, audio and video imaging to explore the mechanism of articulation errors among patients with DFD. Furthermore, our lab is conducting a longitudinal study of DFD patients to determine if jaw surgery improves speech distortions, in collaboration with oral surgeons, linguistics and speech pathology. -An additional focus of our lab has been studying use of Animal Assisted Therapy for management of anxiety and pain in dentistry. Dental anxiety effects 21-50% of patients and is associated with poor long-term oral health outcomes and need for urgent care due to dental avoidance. Non-pharmacological behavior interventions like dog therapy holds promise for reducing pain and anxiety perception for patients, and therefore improving dental experiences and promoting improved health outcomes. The lab is conducting a randomized controlled trial to evaluate best practices for canine therapy in pediatric dentistry, in collaboration with pediatric dentists, a psychology professor whose expertise is anxiety, and the UNC Biobehavioral Lab. -As part of the COVID-19 research response, we are studying FDA-approved antiseptic mouth rinses for their ability to limit salivary viral infectivity to reduce risk of SARS-CoV-2 transmission. If an oral rinse is found to be efficacious at inactivating the SARS-CoV-2 virus, it could be a valuable preventative measure in settings where masks are removed, such as dental care, social settings, eating out, or work presentations. This study is conducted in collaboration with leading virologists and infectious disease experts at UNC. |

PHD PROGRAM RESEARCH INTEREST |
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. |

PHD PROGRAM RESEARCH INTEREST |
Our dynamic group are broadly involve in three topics: (i) prevention of infectious diseases by harnessing interactions between secreted antibodies and mucus, (ii) immune response to biomaterials, and (iii) targeted delivery of nanomedicine. Our group was the first to discover that secreted antibodies can interact with mucins to trap pathogens in mucus. We are now harnessing this approach to engineer improved passive and active immuniation (i.e. vaccines) at mucosal surfaces, as well as understand their interplay with the mucosal microbiome. We are also studying the adaptive immune response to polymers, including anti-PEG antibodies, and how it might impact the efficacy of PEGylated therapeutics. Lastly, we are engineering fusion proteins that can guide targeted delivery of nanomedicine to heterogenous tumors and enable personalized medicine. |

Our lab focuses on the life cycle of cancer-associated human papillomaviruses (HPV); small DNA viruses that exhibit a strict tropism for the epithelium. Several studies in our lab focus on the interface of HPV with cellular DNA damage response (DDR) pathways and how HPV manipulates DNA repair pathways to facilitate viral replication. We are also interested in understanding how the viral life cycle is epigenetically regulated by the DDR as well as by other chromatin modifiers. Additionally, we are investigating how HPV regulates the innate immune response throughout the viral life cycle. |

PHD PROGRAM RESEARCH INTEREST |
We are interested in unraveling the molecular basis for human disease and discover new treatments focused on human and microbial targets. Our work extends from atomic-level studies using structural biology, through chemical biology efforts to identify new drugs, and into cellular, animal and clinical investigations. While we are currently focused on the gut microbiome, past work has examined how drugs are detected and degraded in humans, proteins designed to protect soldiers from chemical weapons, how antibiotic resistance spreads, and novel approaches to treat bacterial infections. The Redinbo Laboratory actively works to increase equity and inclusion in our lab, in science, and in the world. Our lab is centered around collaboration, open communication, and trust. We welcome and support anyone regardless of race, disability, gender identification, sexual orientation, age, financial background, or religion. We aim to: 1) Provide an inclusive, equitable, and encouraging work environment 2) Actively broaden representation in STEM to correct historical opportunity imbalances 3) Respect and support each individual’s needs, decisions, and career goals 4) Celebrate our differences and use them to discover new ways of thinking and to better our science and our community |

PHD PROGRAM RESEARCH INTEREST |
Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen responsible for a variety of diseases in individuals with compromised immune function. Dr. Wolfgang’s research focuses on the pathogenesis of Pseudomonas aeruginosa infection. The goal of his research is to understand how this opportunistic pathogen coordinates the expression of virulence factors in response to the host environment. Projects in his laboratory focus on the regulation of intracellular cyclic AMP, a second messenger signaling molecule that regulates P. aeruginosa virulence. Dr. Wolfgang’s laboratory uses a combination of molecular genetics and biochemical approaches to understand how P. aeruginosa controls the synthesis, degradation and transport of cAMP in response to extracellular cues. Other related projects focus on the regulation and function of P. aeruginosa Type IV pili (TFP). TFP are cAMP regulated surface organelles that are critical for bacterial colonization of human mucosal tissue. In addition, the Wolfgang lab is actively involved in characterizing the lung microbiome of patients with chronic airway diseases and studying the interactions between P. aeruginosa and other bacterial species during mixed infections. |
