research overview
- I am interested in how insects work. My core research area is insect nutritional physiology (how insects process food for growth and reproduction), including the contribution of symbiotic microorganisms to insect nutrition. The three current research foci in the laboratory are: Insect-plant interactions, especially nutrition of plant sap-feeding insects. We are addressing how the insects process two classes of plant nutrients: sugars, which are both the dominant carbon source and osmotic challenge for these insects; and sterols, which are essential component of cell membranes and precursor of insect ecdysteroid hormones. Our research includes interference with the function of insect sugar processing genes and studies of modified plants with altered sterol content, as novel control strategy for phloem-feeding insect pests. The obligate intracellular symbioses in insects. We focus almost entirely on the symbiosis between aphids and the bacterium Buchnera, which is supported by excellent genomic resources and is amenable to nutritional physiological techniques. We have demonstrated that Buchnera provide aphids with essential amino acids, nutrients in short supply in the aphid diet of plant phloem sap. Currently, we are seeking to identify key genes mediating the interactions between insect and bacteria and to establish their mode of action. This involves mining genomes for candidate genes, metabolic reconstruction, transcriptome and proteome analysis and the physiology of nutrient utilization by insects and isolated bacteria. We are motivated by the fundamental problem of how the bacteria have become integrated into the physiological system of the insect, and by the potential of key symbiosis genes as targets for insect pest management. Drosophila-gut microbe interactions. We are investigating the composition of the gut microbiota by molecular and microbiological methods, and how the presence and composition of the microbiota interacts with the nutritional condition and immunological function of the insect. Our purpose is to use this association, as a general model system for animal-gut microbe interactions.

outreach overview
- The principal outreach activity of 2010 was the delivery of a one-day workshop to high school teachers. This included a lecture, a laboratory class, and informal discussion. The success of this activity was evaluated by feedback forms organized by The Cornell Institute for Biology Teachers. The feedback was excellent. laboratory class is under discussion for piloting as a classroom activity in the region by The Cornell Institute for Biology Teachers. The success I continue to take opportunities to communicate our science to the general public, including through the annual Insectapalooza event in the Department of Entomology. I seek to engage with the general public and non-specialists in topical biological issues, especially as they relate to my expertise. I have provided lectures and contributed to discussion panels on topics ranging from 'cooperation in nature' to beneficial microorganisms and aphids as pests. I have also contributed to courses for in-service training of secondary school teachers, especially on evolution.
