UNCG Campus Weekly

Campus Weekly is published each Wednesday when classes are in session. In the summer, it is published biweekly.

Dr. Martin Tsz-Ki Tsui

Dr. Martin Tsz-Ki Tsui (Biology) received new funding from the University of North Carolina System for the project “New focus on a regional problem in eastern NC: What are the impacts of increased salinity on mercury, parasite prevalence in fish, fishing behaviors and perceptions of human health risk?”  

According to the abstract, fish are widely contaminated by mercury throughout eastern North Carolina. Sea level rise may salinize regional wetlands, potentially elevating fish mercury levels and parasite infection, but the effects have not been examined. Similarly, the perceptions of local fishers and fish consumers regarding to the risks posed have not been explored. Dr. Tsui hopes to form an interdisciplinary team with four assistant professors from three UNC campuses to tackle the issue, in both the short and long terms. Outputs from this IPG funding will help boost the team and position it to pursue further funding at state and federal levels.


Dr. Olav Rueppell

According to the abstract, honeybee health is compromised by the ectoparasitic Varroa mite. One promising avenue for sustainable control of this pest is selective breeding for mite resistance. Based on an existing breeding program in Israel, this collaborative research seeks to better understand the phenotypic and genetic architecture of a key trait, hygienic behavior, of the natural resistance of honey bees to Varroa mites. In addition to the study of select crosses and QTL mapping, this study will verify molecular markers in general association studies and investigate the potential for breeding hygienic honey bees under natural conditions.

Dr. Wei Zhong

Portrait of Dr. Wei Zhong Dr. Wei Zhong (Translational Biomedical Research) received new funding from the National Institute on Alcohol Abuse and Alcoholism for the project “DUOX2 Dysfunction in alcohol-induced host-microbiota dyshomeostasis.”

“Alcoholic liver disease (ALD) is a major cause of morbidity and mortality in the United States. It is estimated that 15-30% heavy drinkers develop advanced liver disease. According to the report from the World Health Organization in 2014, alcoholism results in about 3.3 million deaths worldwide annually, which correspond to 5.9% of all mortality. Unfortunately, FAD-approved therapies are currently not available. The major obstacle is the limited understanding of the pathogenesis of ALD.

“Clinical studies have shown that only alcoholics with gut leakiness develop liver injury. The gut is the first site of injury upon alcohol consumption. Increasing evidence suggest that alterations of intestinal microbiota (dysbiosis) contribute to alcohol-induced intestinal and systemic injury. However, the mechanism of how and to what extent alcohol hampers host response to enteric dysbiosis and organ injury remains largely unclear. THe project was designed to answer this key question.”

Dr. Jennifer Coffman

Portrait of Dr. Jennifer Coffman Dr. Jennifer Coffman (Human Development and Family Studies) received a continuation of funding from the DOED Institute of Education Sciences for the project “Student Learning as a Function of Exposure to Teachers’ Use of Cognitive Processing Language During Instruction.”

“Given the importance of basic memory skills for success in school, it is essential that we understand the development of a range of component skills that (1) affect the acquisition of knowledge and strategy use and (2) emerge in the context of the classroom, (3) are transformed over time into the study skills that are needed for progress in school, and (4) are related to measures of academic achievement,” the abstract states. “To examine the developmental course of these skills and the factors that affect their development, we have carried out both longitudinal and experimental research on the key role of teachers’ Cognitive Processing Language (CPL). This language is rich in references to metacognition, cognitive processes, and requests for remembering, and is important for the development of memory strategies and later study skills. In this study, we will establish two cohorts of 100 children in North Carolina and track them longitudinally from Kindergarten through the beginning of Grade 2.”

Dr. Nadja Cech

Portrait of Dr. Nadja Cech Dr. Nadja Cech (Chemistry and Biochemistry) received new funding from the University of Colorado Denver for the project “Impact of commensal cross-talk on MRSA colonization and infection.”

Dr. Cech and Dr. Alexander Horswill of the University of Colorado Denver received funding to study how beneficial bacteria on skin form a protective barrier that prevents infection by dangerous bacterial pathogens. The hypothesis for their collaborative project is that ‘beneficial’ bacteria that live on healthy skin produce chemical signals that interfere with the communication systems used by harmful infection-causing bacteria.  These chemical signals prevent harmful bacteria from taking up residence on (colonizing) our skin.

To test this hypothesis, Cech and investigators are working to identify the chemical signals produced by beneficial bacteria, while the Horswill group studies the influence of these molecules on would-be bacterial invaders.  The team seeks to provide new insights into the complex interactions that occur among bacteria that comprise the skin microbiome, with the ultimate goal of developing new strategies to treat and prevent deadly bacterial infections.

Dr. David L. Wyrick

Portrait of Dr. David Wyrick Dr. David L. Wyrick (Public Health Education) received new funding from Prevention Studies, LLC, for the project “Proposal to Evaluate the D.A.R.E. America Delivery of Elementary and Middle School ‘keepin’ it REAL.’”

According to the abstract, the UNCG Institute to Promote Athlete Health and Wellness has been subcontracted by Prevention Strategies to conduct a systematic evaluation of both the elementary school and middle school versions of the “keepin’ it REAL”program as delivered by trained D.A.R.E. officers. By allowing Prevention Strategies to conduct the evaluation, an independent assessment of program effectiveness will be provided. The goal of the project is to determine effectiveness, submit results for scientific publication and help D.A.R.E. America qualify the programs as evidence-based programs.

Dr. Tracy Bartlett

Portrait of Dr. Tracy Bartlett Dr. Tracy Bartlett (Nursing) received new funding from the American Association of Colleges of Nursing (AACN) for the project “The Jonas Veterans Healthcare Scholar Program 2018-2020.”

According to the abstract, funds will be awarded by AACN on behalf of the Jonas Center for Nursing and Veterans Healthcare to universities over a two-year grant period. The Jonas Center has chosen UNC Greensboro to participate in the Jonas Scholar Program with grants to support one PhD Jonas Nurse Leader Scholar with scholarships.

Dr. Igor Erovenko

Portrait of Igor Erovenko Dr. Igor Erovenko (Mathematics and Statistics) received new funding from Occidental College for the project “Center for Undergraduate Research in Mathematics.”

According to the abstract, the project will offer four students from UNCG and Bennett College a research project in the field of mathematical biology that can be informally called “vaccination games.” It involves applying game-theoretic methods to individual decisions on the use of personal protective measures against an infectious disease. The project will address the question of whether an infectious disease can be eradicated through voluntary participation in personal protective measures like vaccination.

Erin Lawrimore

Portrait of Erin Lawrimore Erin Lawrimore (University Libraries) received new funding from the North Carolina State Library for the project “Developing Archival Processing Services for Smaller Institutions in North Carolina.”

According to the abstract, the project allows archivists from UNC Greensboro and other repositories to explore creation of a statewide archival processing service. This service would provide smaller cultural heritage institutions with assistance in arranging and describing their archival collections, thereby providing researchers with greater access to collections often considered “hidden.” Through this grant, the Steering Committee will explore the most effective ways of providing these services as well as the scope of the future service.

Joshua Kellogg

Portrait of Joshua Kellogg Joshua Kellogg (Chemistry and Biochemistry) received new funding from the National Institutes of Health for the project “Complex Natural Product Mixtures Against Drug Resistant Infections: Targeting Multiple Pathways to Combat Bacteria.”

According to the abstract, many dietary supplements are used in the form of complex mixtures, and their purported efficacy is often attributed to the presence of multiple constituents with combined activity greater than that of individual metabolites. Such mixtures can potentially target multiple pathways to exert their effects. Indeed, pharmaceutical combination therapy approaches have become standard interventions for diseases such as cancer, diabetes, HIV/AIDS, and malaria. The complexity of dietary supplements poses a major challenge, and there is currently a lack of knowledge for many of these supplements as to the mechanisms that underlie their biological effects, and whether activities observed at the cellular level translate into more complex model systems. Very few studies have investigated whether components of a complex mixture work in combination to affect a phenotypic response. The goal of these studies is to conduct both in vitro and in vivo studies to evaluate the mechanisms that underlie biological activity of a complex natural product mixture.

Dr. Dianne Welsh

Dr. Meredith Powers

Dr. Meredith Powers (Social Work) received new funding from The Junior League of Greensboro, North Carolina, Incorporated, for the project “Parks for All People: Promoting Health and Wellness by Engaging Aging Populations in Public Parks.” D. Justin T. Harmon and Dr. Benjamin D. Hickerson are co-principal investigators on the project.

According to the abstract this project will focus on the health and quality of life needs of older adults in Greensboro through the rehabilitation of neighborhood parks to better serve their recreational and leisure preferences in public spaces. This project will benefit from the Junior League of Greensboro grant by building on an existing community partnership between the Department of Community and Therapeutic Recreation and the City of Greensboro’s Parks and Recreation Department. The abstract states that there are more than 100 neighborhood parks in Greensboro, with few of them adequately serving the specific needs of an aging population. The project’s partnerships for park enhancements are crucial in order to increase accessibility (e.g., wheelchair paths, benches) and participation of older adults in these public spaces.

Dr. Stephen Sills

Dr. Stephen Sills (Center for Housing and Community Studies) received new funding from the Community Foundation of Greater Greensboro for the project “UNCG Eviction Diversion Research Project (EDRP) for the Development of an Eviction Diversion Program.”

The goal of the project is to reduce the displacement of families and individuals from their homes through unfair and unnecessary eviction. The abstract states such evictions lead to increase financial burdens and sometimes homelessness of displaced occupants. The programs that will be developed through this research project will identify and seek a mutually beneficial resolution with landlords to allow occupants to remain in their homes by mediating late or outstanding rents and other payments owed by the tenant. The benefits of the programs will be examined by conducting a Return on Investment and Cost Saving analysis for the community, courts, landlords, social services and families.


Three UNCG faculty (Dr. Rob Cannon, Dr. Jeremy Ingraham and Robin Maxwell) represented UNCG at the annual meeting of the National Association of Advisors for the Health Professions in Washington, DC, from June 27 to July 1.

Dr. Tsz-Ki Tsui

Dr. Tsz-Ki Tsui (Biology) received new funding from  Clemson University for the project “Storage, Reactivity, and Bioavailability of Mercury in Managed Forests – Balancing Mercury Toxicity and Wildfire Risks through Effective Fuel Reduction Techniques.”

This project is supported by funds from the USDA National Institute of Food and Agriculture (NIFA).

The abstract notes that prescribed burning and mechanical thinning are essential forest management practices in the Southeastern U.S., having many beneficial objectives including reduction in the susceptibility of forests to both southern pine beetle attack and wildfires. The four-year project will involve controlled field studies, laboratory studies, and watershed monitoring study to evaluate prescribed burning and mechanical thinning practices, roles of OM/DOM, formation of black carbon, and landscape processes on the transport of different forms of Hg via catchments and downstream Hg transformation mainly microbial methylation. Forest floor sample materials will be collected from experimental plots with different burning schedules and frequency and will be incubated under field conditions. Forest floor materials under different practices will be further tested for their propensities in leaching Hg and further methylation. An unmanaged and a managed 1st order watershed at three locations in North Carolina and South Carolina will be used to evaluate the landscape processes on the exports of Hg. With the results of the control study and field investigation, a box model describing production of methylmercury, toxic form of mercury, in forested ecosystems under different forest management practices will be developed.

Dr. Holly Sienkiewicz

Dr. Holly Sienkiewicz (Center for New North Carolinians) received new funding from the New Arrivals Institute for the project “Refugee After School Program.” The abstract notes that many newly arrived refugee children need additional support and tutoring to achieve success in school. They also need the opportunity to experience activities that they might not otherwise get to experience such as Girl Scouts, sports activities and field trips. Adult refugees need help with employment assistance and English as a Second or Other Language (ESOL).

The project’s objective is to prepare refugee children for success in school and adults for the workforce. An after-school tutoring program, social enrichment activities, and ESOL and employment readiness will be provided at two CNNC community centers that provide services to refugees.
