About Dawn

I grew up on a cattle ranch in NE Nevada and began my research career as a Biochemistry undergraduate at the University of Nevada, Reno in the Allie M. Lee Natural Products Lab. My graduate research with Dr. Ruth Billings, a toxicologist in the Pharmacology department at UNR and later Environmental Health Sciences at CSU, explored the ability of cytokines to induce nitric oxide synthase expression in hepatocytes and the potential role this induction plays in liver damage. I expanded my understanding of mechanisms of gene regulation by completing post-doctoral fellowships with Dr. Colin Clay in the Physiology Department (now Biomedical Sciences) at CSU and as a postdoctoral fellow and junior faculty member in the Endocrine Division at the Univ. of Colorado School of Medicine. Current projects utilize next generation sequencing methods to explore genetic and gene expression changes contributing to cancer development, metastatic progression, and drug sensitivity in models of canine cancer including osteosarcoma and bladder cancer.
