Rosa daSilva, Ph.D.
My research interests in the laboratory are focused on the cellular and molecular mechanisms that underlie systemic animal physiology, developmental biology, and both human and comparative anatomy and physiology. In particular, I am interested in the molecular and cellular biology of cell-cell interactions, motility, and proliferation, with emphasis on how interrupted protein-protein interactions can lead to aberrant cellular activity such as tumorigenesis and cancer.
I focus the emphasis of my pedagogical research on re-engaging students back into the classroom through the use of social media and emerging technologies. Through these means, my specific interests lie in connecting students with topics discussed within my classrooms using real-time scientific discoveries to develop student scientific literacy in the digital age.

My primary research interests deal with the cellular and molecular mechanisms that regulate various systemic processes within model organisms. Much of this research has included work on insect model organisms to better understand digestive, renal, cardiac, neural and reproductive processes. In particular, I have identified various regulating proteins and signalling cascades that control the cellular machinery and are vital to maximize overall systemic physiology. In previous research, I have also investigated the role of microtubule associated proteins in the differentiation of osteoblasts during bone development, as well as examining the role of various scaffolding proteins in the process of cancer cell metastasis in an osteosarcoma bone cancer model.
