Margaret “Peggy” Bush joined the DUSON faculty in December, 2012. She will assume co-teaching responsibilities for the Pharmacology courses in both the MSN and ABSN programs. Dr. Bush has more than ten years' experience teaching pharmacology. Her research experience has focused on clinical drug development in the areas of oncology and hematopoietic growth factors. She has practiced as a pharmacist in both hospital and retail settings.

Dr. Bush earned a BS in Pharmacy from The Ohio State University, an MBA in Health Administration at Cleveland State University, and a PhD in Pharmacology from the University of California, Los Angeles. Dr. Bush recently completed a graduate certificate in E-Learning from North Carolina State University. Her professional interests include identifying instructional strategies for teaching pharmacology that engage learners and promote critical thinking through the use of problem-solving approaches.

Academic Program Affiliations

Research Interests

Dr. Bush’s clinical research experience includes study design and protocol development, operations, management and reporting for Phase 1 through Phase 3 investigational drug studies. Her experience has focused in the areas of oncology and hematopoietic growth factors. Her basic research while at UCLA, identified nitric oxide as the mediator of nonadrenergic, noncholinergic neurotransmission that leads to vascular smooth muscle relaxation in erectile tissue, providing the pharmacological rationale for subsequent clinical development of phosphodiesterase-5 inhibitor drugs for the treatment of erectile dysfunction.
