Frances E. Weaver PhD

Associate Dean of Science

  • PhD Cell Biology 1985

    Johns Hopkins University (MD)

  • BIOL 161 Biological Concepts I Principles of Evolution and Ecology

  • BIOL 306 Developmental Biology

My research interests focus on molecular mechanisms, that is the activities at the DNA, RNA, or protein level that influence cellular and thereby organismal properties. I also have long standing interests in embryonic and post-embryonic development. In my research here at Widener, I have applied molecular biological techniques to the study of the embryology of horseshoe crabs, the muscle physiology of fish, and the immune responses of frogs.

My research projects have been undertaken with the twin goals of increasing biological knowledge in these areas and supporting participation by undergraduate students. My students and I have an enormous amount of fun learning together, and I take great pride in the accomplishments of each and every one of them.

My current project is on gene expression in horseshoe crab embryos (Limulus polyphemus). My students work to identify previously unknown genes and determine their expression patterns during embryonic development in these organisms.
