Biography
Dr. Cox obtained her Ph.D. from the Curriculum in Genetics and Molecular Biology at University of North Carolina – Chapel Hill in 1992. She carried out her thesis work in the laboratory of Dr. Mark Peifer where she used the model organism Drosophila melanogaster to uncover how the highly conserved protein Armadillo/beta-catenin functions in cell-cell adhesion and cell signaling during development. After a year as a postdoctoral fellow in the Peifer lab, she went on to do a postdoctoral fellowship in the laboratory of Dr. Alan Spradling in the Department of Embryology, Carnegie Institute for Science in Baltimore, MD. There, she began studying the molecular mechanisms governing mitochondrial movement and function during Drosophila oogenesis. In 2008, Dr. Cox obtained an independent tenure track position at Uniformed Services University in the Department of Biochemistry and Molecular Biology where she continues her research on mitochondrial function and quality control during development and disease.

Biography
Chronic diseases and even aging itself are known to damage the body by dys-regulated inflammatory processes. Dysregulated expression of the pro-inflammatory cytokine and chemokine genes are known to contribute to chronic inflammatory diseases. Recently, endogenous non-coding RNA (ncRNA) molecules, including long non-coding RNAs (LncRNAs) and microRNAs (miRNAs, miRs) have emerged as important targets in the frontier of biomedical research. These non-coding RNAs have been proven to be key regulators of gene expression. The ability to detect non-coding RNAs in biofluids has highlighted their usefulness as non-invasive markers of diseases, including lung diseases. The expression of specific non-coding RNAs is altered in many lung diseases and their levels in the circulation often reflect the changes in expression of their lung-specific counterparts. Therefore, exploiting these biomolecules as diagnostic tools seems an obvious goal. Our goal is to investigate the role of non-coding RNAs in Cystic Fibrosis lung disease and develop novel anti-inflammatory therapeutics for pulmonary disorders.
