Todd Downes, Business Manager
Melissa Troester, Ph.D., Center Director
The Administrative Core of the UNC-CEHS provides administrative and scientific leadership, manages Center finances and resources to facilitate research related to our three focus areas, and supports activities in the Career Development Program, the Pilot Projects Program, Facility Cores, and the Community Engagement Core.
Melissa Troester, Director
Melissa Troester, Ph.D., is Center Director. The Troester laboratory studies breast cancer and benign breast disease using genomic, molecular pathology, and epidemiologic approaches. Much of Dr. Troester’s research focus has been on understanding interactions between the environment and breast genomics. She is Co-Principal Investigator on the Carolina Breast Cancer Study (CBCS), a study of breast cancer epidemiology and biology focused on understanding breast cancer disparities and she is Co-Leader of the Lineberger Comprehensive Cancer Center’s Cancer Epidemiology program. She has extensive experience working in consortia, including the African American Breast Cancer Epidemiology and Risk (AMBER) consortium, the Breast Cancer Association Consortium (BCAC), and the Cancer Genome Atlas project. In the TCGA, she led analyses of benign breast genomics. A common theme throughout her work is integrating genomic data and molecular biology with human studies of breast cancer etiology and progression.
Stephanie Engel, Deputy Director and Research Director for Developmental Disease
Dr. Engel, Ph.D., is the Deputy Director and Research Director of the developmental disease research theme for the CEHS. She has led multiple national and international studies of maternal and child epi/genetic variability in relation to prematurity, growth restriction, preeclampsia and gestational hypertension. Her research is at the interface of innate and exogenous exposures during the prenatal and early childhood periods, and how they work together to influence the development of the child. She has ongoing projects in the area of maternal and fetal genetic, epigenetic, and metagenomic variation and pregnancy outcome, and the relationship of prenatal environmental exposures with childhood neurodevelopmental impairments such as ADHD. Many of the environmental exposures she studies are over-represented in minority and low income populations, which leads to the potential for unique susceptibilities in high risk communities.
Michael Sanderson, Associate Director
Michael Sanderson, MPH, is the CEHS Associate Director. He oversees and manages administrative and research activities, including promoting and fostering new CEHS research collaborations, supporting research and programmatic activities, and encouraging pilot project development.

Mary has formal training in Clinical Research and Project Management and looks forward to utilizing her broad research experience to advance innovative environmental research at the UNC CEHS.
Cyrus Vaziri, Research Director for Environmental Cancer
Dr. Vaziri, Ph.D., is the Research Director of the environmental cancer research theme for the CEHS. The Vaziri lab seeks to address two related problems in the area of environmental cancer: (1) How do neoplastic cells alter their genomes during carcinogenesis? and (2) How do pre-neoplastic cells tolerate the intrinsic DNA damage and replicative stresses associated with carcinogenesis? Trans-Lesion Synthesis (TLS) is an error-prone (mutagenic) and damage-tolerant mode of DNA synthesis. The Vaziri team has shown that TLS is pathologically-activated in cancer cells and confers tolerance of oncogene-induced DNA replication stress. Thus, pathological TLS provides a new mechanism for sustaining viability of neoplastic cells while simultaneously causing the mutations that drive tumor progression. Cancer cells depend heavily on DNA damage tolerance and mutagenesis to adapt and resist therapy. Therefore, an important byproduct of the selective pressure for TLS-mediated DNA damage tolerance during tumorigenesis is emergence of chemoresistant cancer cells. Pathological TLS represents a molecular vulnerability and an appealing therapeutic target whose inhibition will sensitize tumors to intrinsic or therapy-induced DNA damage.
Ilona Jaspers, Research Director for Cardiopulmonary Disease
Ilona Jaspers, Ph.D., is the Research Director of the cardiopulmonary research theme for the CEHS. She is a Professor at the University of North Carolina at Chapel Hill (UNC-CH) in the Department of Pediatrics with joint appointments in the Departments of Microbiology and Immunology as well as Environmental Sciences and Engineering. Dr. Jaspers has a long-standing interest in the adverse health effects induced by pollutant exposures. She collaborates extensively with investigators from UNC-CH and the U.S. Environmental Protection agency to conduct translational studies related to air pollution health effects. Research in Dr. Jaspers’ laboratory focuses on the mechanisms by which exposure to air pollutants such as ozone, woodsmoke, cigarette smoke, and e-cigarettes modifies host defense responses, using translational human in vitro and in vivo models. As the Director of the Curriculum in Toxicology, Dr. Jaspers also oversees the training and mentorship of graduate students and postdoctoral fellows.
Kathleen Gray, Director of the Community Engagement Core
Kathleen Gray, Ph.D., is the Director of the Community Engagement Core (CEC) in the Center for Environmental Health and Susceptibility. Her research focuses on environmental health literacy, science communication and community and stakeholder engagement. In 2015, Dr. Gray was awarded the Office of the Provost Engaged Scholarship Award for Partnership, one of UNC’s highest public service honors, in recognition of a longstanding collaboration with a regional environmental nonprofit and a county park to inform vulnerable populations about the risks of consuming contaminated fish. Within the UNC Institute for the Environment, she manages the Center for Public Engagement with Science, which enhances public understanding of current environmental science and health research and its relevance to daily life. She has over 20 years’ experience conducting environmental health education with community audiences and assisting businesses and government agencies in making sustainable choices. Prior to joining UNC, she led a statewide assessment of NC’s recycling industry, advised over 300 businesses in expanding their use of environmentally responsible products and services, developed and evaluated educational materials for EPA’s voluntary environmental programs, and managed a community-focused environmental health internship program at Vanderbilt University.

She has experience working with biologic specimens in the laboratory, counseling patients for genetic disorders and designing and developing population and hospital-based research studies.
Kun Lu, Director of the Molecular Analysis Facility Core
Kun Lu, Ph.D., is the Director of the CEHS Molecular Analysis Facility Core. The overarching goal of Dr. Lu’s lab is to better understand health effects of environmental exposure and individual response by integrating the microbiome, exposome, omics profiling, and biomarker development. Dr. Lu’s lab is working on a number of important environmental chemicals ranging from heavy metals to pesticides, as well as others with significant public health concerns. The current emphasis is being placed on microbiome research and exposome mapping. Dr. Lu’s lab aims at answering how gut microbiome interacts with environmental exposure, how gut microbiome affects disease susceptibility, and how host factors crosstalk with microbiome to influence its response. Another focus of Dr. Lu’s lab is to map exposome for human disease, with the goals of characterizing all exposures over the lifespan via high-resolution mass spectrometry, understanding the health impact of the exposome, and designing strategies to reduce exposure-associated adverse effects.
