    Genetics & Molecular Biology

Close

All courses for every first-year Science student will be delivered online this fall. A limited number of students in their second, third and fourth years will return to campus for part of the semester.

Molecular Biology is a fundamental area of investigative research in Biology that employs new technologies and experimental approaches to examine fundamental processes in all living organisms. In the course of these investigations, we use wide variety of model organisms, including mice, guinea pigs, human tissue cell cultures, the nematode species Caenorhabditis elegans, the plant Arabidopsis thaliana, model bacteria and the fruit fly Drosophila melanogaster. The research is of immediate relevance to human health in many areas including cancer, inherited genetic diseases and disease resistance, DNA repair, and neurosystem development and function. We welcome strong applicants as undergraduate researchers, graduate students and postdoctoral fellows.

The heart is the organ most often affected by congenital malformations, as well as diseases associated with aging. Uncovering the molecular and genetic mechanisms that underlie these problems can be accelerated through study with simpler genetic models such as the fruitfly, Drosophila. The Jacobs lab employs the Drosophila genetic model to dissect heart formation and growth of the heart, with particular focus on adhesion signaling, cell polarity, morphogenesis and the formation and remodeling of the heart extra-cellular matrix.
