Assistant Professor, Dept. of Biological Sciences
We are a bioanalytical mass spectrometry group focused in two main areas: 1) Technology development spanning separation science, ionization source development, and data acquisition methods, and; 2) Applications of developed technologies toward problems in toxicoproteomics. Toxicoproteomics, a subclass of both proteomics and toxicogenomics, aims to identify the critical proteins/pathways that respond to or are affected by adverse chemical and environmental exposures using both global and targeted protein identification methodologies and ultimately their relationship to disease etiologies. Our group uses both model organisms and longitudinal sampling of biological fluids to help address these questions.

Clinical and research interests are focused on the treatment and prevention of childhood obesity and related co-morbidities including insulin resistance and type 2 diabetes mellitus, non-alcoholic fatty liver disease, dyslipidemias and impaired vascular reactivity and hypovitaminosis D. He is particularly interested in the role of environmental xenobiotics in the maintenance of obesity and/or weight loss failure in clinical populations and is currently investigating the role of benzoic acid in weight loss failure. Dr. Collier is also interested in facilitating a broad range of bidirectional translational research that will leverage the strengths of the CHHE and the large pediatric patient population served by the Brody School of Medicine.
William Neal Reynolds Distinguished Professor, Dept. of Applied Ecology
My research goal is to maintain one of the world’s most productive laboratories investigating the toxicological and ecological threats to native freshwater fauna, focusing on mollusks and non-game fishes, which are among the most imperiled taxa on the planet. We aim to understand and mitigate the effects of pollution and other human-mediated stressors on the natural environment and human health. Our results make a positive influence on science policy and practice in the United States and internationally towards the conservation and management of species. Through our connection with NC Cooperative Extension, we improve people’s lives by building bridges between the acquisition of new knowledge through applied Extension research and demonstration projects and then creating state of the art mechanisms for making this information available to those who need it. Our high impact program develops, translates, and delivers objective, science-based information for the protection of human and environmental health, specifically focusing on the areas of Pesticides and Human Health, Agromedicine, and Water Quality and the Environment.

Research in the Dunn lab includes work on belly buttons and their ecology, the rectal diversity of camel crickets, the composition and consequences of bacteria, fungi, insects and protists in homes, the biology of industrially useful organisms in salt shakers, and the response of large patches of forests to climate change, among other topics. Key to the work done in Dunn’s lab is a fascination with natural history and the extent to which many of the most important consequences of species in forests, bedrooms and bodies relate to species we don’t yet know anything about. Recent work in the lab, for example, has found more than 180,000 life forms INSIDE homes. Some of those life forms are beneficial. A few are deadly. Most just float around landing on you and those you love where they live and die totally unknown. Most of the work done in the Dunn lab directly engages the public in the process of science, whether through music, visual art, citizen science or other means.

Associate Professor, Dept. of Biological Sciences
My research focuses on the human health effects of pesticides and phthalates with particular focus on respiratory and allergic outcomes. We are currently evaluating the impact of specific pesticide exposure in populations with different types of exposure (farmers, rural residents, families living in banana plantations). Using epidemiologic tools to assess exposure and different measures to assess exposure (questionnaires, biological markers, geospatial mapping), we are able to better understand the potential human health consequences of these common exposures.
Associate Professor, Dept. of Biological Sciences
The research in the Epidemiology and Environmental Epigenomics lab (Hoyo, Jirtle and Skaar) involves the identification and characterization of epigenomic marks that that are perturbed by early environmental exposures to alter susceptibility to chronic diseases, including cancer, later in life. We use cohort study design in early life to characterize the timing of exposures, and the stability of epigenetic response over time. We also use case-control designs, to determine the extent to which identified epigenetic marks are associated with chronic diseases. Long term, these epigenetic marks should be developed as assessment biomarkers and to generate hypothesis relating their involvement in the etiology of specific disease pathways.

My research is focused on studying the microorganisms associated with urban pests and understanding their crucial role in the host development and behavior and their impact on human health. German cockroaches and bedbugs are common urban pest species and a major problem in households, animal farms and hospitals. These pests are often associated with health implications such as allergen linked asthma in children and pathogen transmission. I am currently investigating the relationship between insect associated microbes in some pest-infested households in Raleigh and their contribution to the microbial diversity in the respective homes and assessing the risk of occurrence and dispersion of potential pathogens.

Our goal (Occupational and Environmental Epidemiology Branch) is to investigate environmental/occupational issues that may have adverse impacts on humans. This may be accomplished by site visits, recommendations on environmental testing, and risks assessments. The scope of our work ranges from indoor air issues to superfund sites, cancer clusters, fish consumption advisories, occupational injuries, pesticide poisonings to name a few.
Associate Professor, Dept. of Public Health, ECU
Obesity and cancer: Cancer is the #1 cause of death in North Carolina. As our population ages, more of North Carolina’s children and adults will find themselves facing a diagnosis of cancer, a majority of whom will also be obese. My research interest include exploring associations between epigenetic markers of obesity, environmental endocrine disruptors, and diabetes as precursors to pancreatic, colon, and breast cancers. Longitudinal studies from childhood will allow measuring changes in precusor markers and interactions over time. Are obese children likely to develop colon, pancreatic, prostate or breast cancers earlier than non-obese children when reaching adulthood? What are gene-environmental interactions or mediators along the causal pathway? Collaborations within the CHHE center provide opportunity to explore these questions.

The research in the Mitra Organic Geochemistry lab involves studying organic molecules in the environment, both past and present. Some of those organic molecules are made naturally and some result from anthropogenic pollution. We study these organic molecules to try and understand their source, the processes that lead to their transport and transformation, and their preservation over time. With that, we can glean information about past climates, how natural processes such as climate change may affect organic matter cycling in the environment, and understand how certain contaminants may be adversely affecting organisms in an ecosystem. The organic molecules regularly analyzed in our lab include polycyclic aromatic hydrocarbons, pharmaceuticals and personal care products, black carbon, and lignin, as well as bulk stable isotopic tracers of organic matter (e.g. d13C, d15N).

Dr. Runkle’s research interests are in environmental epidemiology with a particular focus on how integrated biological, environmental, and socio-behavioral exposures impact human health, especially the cumulative and interactive effects of health disparities in vulnerable populations. Previous research examined (1) the impact of a technological disaster on health system response and (2) the impact of pesticide exposure and extreme heat on reproductive health in vulnerable female farmworkers. Currently at the North Carolina Institute for Climate Studies (NC-CICS), she is working with a multi-federal agency team to develop the USGCRP report on The Impacts of Climate Change on Human Health in the United States: A Scientific Assessment (release date April 2016). She is a contributing author on Chapter 4. Impacts of Extreme Events on Human Health. At NC-CICS, she is broadening her research interests to include the investigation of population vulnerability to the health effects of climate change.
Blanton J. Whitmire Distinguished Professor, Dept. of Entomology
Our research seeks to elucidate the basic biology of pests that interact with people in residential and other built environments, and to translate this knowledge to innovative and ecologically sound interventions. Cockroaches are important etiological agents of allergic disease and asthma and we seek to understand the sources of allergens, their functions, and intervention strategies to mitigate exposure to potentially harmful allergens. Research on bed bugs seeks to understand their host associations, population genetic structure, and patterns of insecticide resistance. Research in chemical ecology seeks to identify natural products that guide various behaviors of cockroaches, bed bugs, mosquitoes, sand flies, ants and termites.
