Michelle recently established an active vector biology research group within the Boyce Thompson Institute for Plant Research. Her group has a highly interdisciplinary focus where students can learn a wide variety of skills and techniques ranging from plant, vector, and virus molecular biology and genetics, live-cell imaging, plant cell culture and transgenic technologies, biochemical labeling techniques, protein interaction identification, and applications of mass spectrometry. The emphasis of Michelle’s research program is to use a combination of molecular, genetic, and proteomics approaches to understand how insects transmit plant viruses and to discover how viruses manipulate host plants to ensure replication and transmission. A second area of research is in the development of new pest management tools to enhance cultural control and to provide new management strategies of virus diseases in plants.
There is no cure for plant viruses so prevention of insect transmission and infection are key areas of research. Plant viral genomes encode only a handful of proteins, and it is clear that highly tuned virus-host and virus-vector protein interactions ultimately give rise to the stealthy nature of these viruses. Severe knowledge gaps exist in the biophysical mechanisms that vector-borne viruses employ to be transmitted, a stunning fact in light of the devastating impact vector-borne viruses have in food security and public health. The long-term goal of Michelle’s research is to create innovative virus-vector management solutions that could have a disproportionate and transformative impact in resource-poor, food-insecure nations. To achieve this goal, Michelle collaborates on research activities with colleagues at a number of research institutions in the US and abroad.
A major outreach focus of the Cilia lab is providing undergraduate research experiences. Undergraduate students interested in gaining hands on, meaningful research training in the areas of molecular biology, chemical biology, and proteomics are encouraged to contact us. Students who aspire to pursue MS and PhD programs are strongly encouraged to inquire about our exciting opportunities.
