| McCauley, Heather WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
The McCauley Lab is interested in how the food we eat changes our physiology. Rare, nutrient sensing cells in the intestine called enteroendocrine cells secrete hormones in response to environmental cues that orchestrate systemic metabolism. How these cells regulate their neighbors in the gut is not well understood. We use mouse models which lack enteroendocrine cells and human pluripotent stem cell derived intestinal organoids to discover new roles for these master metabolic cells in the regulation of intestinal physiology and function. Enteroendocrine cells are dysregulated in inflammatory bowel disease, type 2 diabetes, and obesity, and loss of enteroendocrine cells results in malabsorptive diarrhea with poor survival. Our research has the potential to improve human health for a wide segment of the global population. |

The human placenta is the first organ to develop after fertilization and is the least studied! We hope to change this by using a multidisciplinary approach. From iPSC-derived trophoblasts in culture to mouse models and human placenta tissue, the Placental Cell Biology Group at NIEHS answers fundamental questions about placenta cell and developmental biology. Our lab uses a range of microscopy (cryo-EM, fluorescence), recombinant protein production, and -omics techniques. The goal of our research is to understand how autophagy controls placenta development, differentiation, and function. |
| Good, Misty WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
The Good Laboratory is focused on the cellular and molecular mechanisms involved in the pathogenesis of a devastating intestinal disease primarily affecting premature infants called necrotizing enterocolitis (NEC). The long-term goal of the Good Lab is to understand the signaling pathways regulating the uncontrolled immune response in NEC and how these responses can be prevented through dietary modifications or targeted intestinal epithelial therapies. Her basic and translational research utilizes a bench-to-bedside approach with multiple cutting-edge techniques. In her pre-clinical studies, their team utilizes a humanized neonatal mouse model of NEC to understand the signaling pathways and immune cell responses involved in NEC development. Specifically, the laboratory interrogates ways to modulate the immune response, epithelial cell and stem cell regeneration as well as early microbial colonization during NEC. In the clinical component of her research program, Dr. Good leads a large multi-center NEC biorepository for the dedicated pursuit of molecular indicators of disease and to gain greater pathophysiologic insights during NEC in humans. Dr. Good also developed a premature infant intestine-on-a-chip model to study NEC and provide a personalized medicine approach to test new therapeutics. Her laboratory is currently funded with multiple NIH R01 grants and has previously received K08 and R03 funding as well as awards from the March of Dimes, the Gerber Foundation and the NEC Society. |

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 |
Building a functioning brain requires an elaborate network of interactions between neurons and glia. We use mouse genetics, primary cell culture, quantitative proteomics, molecular biology, and super resolution microscopy to study glial cells during brain development. We are particularly interested in how astrocytes acquire their complex morphology and communicate with neighboring astrocytes, neurons, and oligodendrocytes. Furthermore, we are investigating how glial dysfunction drives the pathogenesis of brain disorders such as autism, schizophrenia, and leukodystrophy. |
| Morris, John WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
The Morris lab leverages flexible mouse models of hard to treat cancers of the pancreas and liver to identify how cancer drivers perturb evolutionarily selected developmental programs and how such programs may be re-normalized. We focus on (1) the relationship between tumor suppressor pathways and the epigenetic determinants of cell plasticity, (2) evolutionary routes unleashed by specific tumor suppressor loss, and (3) how diversification at both the epigenetic and genomic level contribute to cancer development and therapeutic response. |
| Shpargel, Karl WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
Our laboratory studies the coordination of histone-modifying enzymes in regulating chromatin structure, enhancer activation, and transcription. We utilize mouse genetics and cell culture model systems to study the mechanisms of enhancer activation in neural crest cell epigenetics, craniofacial development, and altered enhancer regulation in cancer. This is accomplished through a variety of techniques including mouse mutagenesis, fluorescent reporters to isolate primary cells of interest, low cell number genomics, and proteomic approaches. |
| Gladden, Andrew WEBSITE PUBLICATIONS |
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. |
| Parnell, Scott E. WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
Our research focuses on the genetic and cellular mechanisms that underlie how prenatal exposure to alcohol and other drugs, such as cannabinoids, disrupt normal brain development. We use a wide variety of molecular and cell biology tools including RNA-seq (whole transcriptomic profiling), mouse transgenics, and confocal imaging to understand how drugs alter cell signaling pathways and transcriptional regulation in development. Our work also studies key regulatory pathways, such as Sonic hedgehog (Shh) and other primary cilia-mediated signals, during normal and aberrant embryonic development. |
| Gordon, Kacy PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
The Gordon lab is brand new to UNC, and studies stem cell and stem cell niche biology in the model organism C. elegans. The germ line stem cells make the gametes, which make the next generation of worms. These cells are therefore at the nexus of development, genetics, and evolution. We will be getting started with projects pertaining to evolutionary comparative gene expression in the stem cells and stem cell niche and niche development. The techniques we use include molecular biology, CRISPR/Cas9-mediated genome editing, worm genetics, and microscopy. |
