Back to DirectoryDana Pirone Ward, Ph.D., is a 1997 graduate of Mount St. Mary’s University. She went on to earn her doctorate in 2001 in Cancer Biology from Georgetown University in Washington, DC. Following her graduate studies, Ward pursued a postdoctoral fellowship in the field of Bioengineering at the Johns Hopkins University School of Medicine in Baltimore, Maryland. During this time she was awarded a National Research Service Award from the National Institutes of Health for her work in the area of vascular cell growth. She continued her postdoctoral studies at the University of Pennsylvania in Philadelphia, PA, where she investigated the role of physical forces on vascular growth.
Ward joined Mount St. Mary’s University in 2007 in the Department of Science, where she teaches Introductory Biology, Anatomy and Physiology I and II, Genetics, Pathophysiology, and Cancer Biology. She also continues to pursue research in the area of vascularization and vascular disease. During her time at Mount St. Mary’s, Ward has received several grants to fund her research including ones from the American Heart Association and the National Science Foundation.

The goal of our research is to investigate how cells control the reorganization of their internal support structures (the actin cytoskeleton) to elicit changes in cell shape ultimately allowing cells to be able to move and migrate. Cell shape changes and cell migration are important drivers for wound healing, but they also underlie pathological processes like cancer metastasis. Understanding how cells regulate complex biophysical phenomena like changing shape and moving will yield insight into both normal processes and disease states.
More specifically, we investigate the function of a small family of Cdc42 effector proteins in controlling the reorganization of the actin cytoskeleton to regulate the major cell shape changes that govern cell migration. We use microfabrication and engineered extracellular environments to explore these processes in spatially and geometrically well-controlled ways. Thus, our laboratory is at the interface of cell biology and bioengineering.
I enjoy interacting with students throughout their journey in higher education and I have developed a research program that integrates undergraduate students in every step of the research progress, including experimental design, data acquisition, data analysis, and oral and written communication of research findings. I enjoy helping students to ignite their passion for discovery and explore their research interests in the lab.
