Biography

Susan Tilton is a Senior Research Scientist in the Computational Biology and Bioinformatics Group at the Pacific Northwest National Laboratory.

Dr. Tilton has a Ph.D. in toxicology with expertise in microarray data analysis and the use of comparative high-throughput technologies (DNA, RNA, protein) to evaluate mechanisms of environmentally-induced disease and develop candidate biomarkers of disease progression. Her research experience is in the areas of environmental health, carcinogenesis, dietary chemoprevention, in utero susceptibility to disease, reproductive and developmental toxicology, and epigenetics with an emphasis on cross-species extrapolations. Currently, Dr. Tilton is applying statistical and computational approaches, including biological pathway analysis, functional enrichment and network modeling, to identify critical pathways of chemical toxicity.
