I am currently Associate Director of Educational Innovation in the Center for Geospatial Analytics in the College of Natural Resources at North Carolina State University. My research and professional experience centers on pedagogical advances in place-based education and geospatial curriculum development at all levels, increasing under-represented students in STEM education and careers, in addition to environmental decision-making under uncertainty and examining the link between the environment and public health. I employ tools, such as geospatial analysis, geostatistics, and probabilistic inference in applied settings to improve our understanding of environmental systems and provide guidance to make more informed environmental decisions as it relates to environmental health and public health risk and exposure. I have several years experience working in environmental and health consulting as well as in academic settings in research, teaching, and mentor capacities, with both undergraduates and graduate students. I also have a strong interest in research and academic administration, along with research and academic mentorship of underrepresented groups.

Cadmium exposure and MEG3 methylation differences between Whites and African Americans in the NEST Cohort
Environmental Epigenetics, 5(3).
Contributors: J. House n , J. Hall n, S. Park n, A. Planchart n , n , R. Maguire n, Z. Huang *, C. Mattingly n
Ed(s): M. Skinner
author keywords: maternal exposures; imprinted genes; offspring epigenetics; cadmium; CpG methylation; racial epigenetic outcome differences
TL;DR:
Data support that prenatal Cd exposure is associated with aberrant methylation of the imprint regulatory element for the MEG3 gene cluster at birth, and neither house-dust nor water are likely exposure sources, and ingestion via contaminated hands is also unlikely to be a significant exposure route in this population.
