This project seeks to elucidate nutritional, genetic, and nutrient-gene interactions as predictors of tuberculosis susceptibility in early childhood and to establish genetic variants in people with HIV-1 infection that affect iron metabolism and the progression to advanced HIV infection and associated mortality.
Powdery mildews are a remarkably diverse group of fungi that attack many important crops. Their ability to produce vast numbers of infectious spores is the driving force of the disease. In a series of experiments, we identified key wavebands of light that shut down spore production. In effect, we have taken an environmental cue that the fungus uses in spore production and turned it against itself.
Our research uses the soil worm C. elegans as a model to study genes that affect aging. Many genes that affect aging in C. elegans also work in humans. Our research will have impact on human aging and age-related diseases, such as cancer, heart disease, diabetes, and neurodegeneration.
The overall goal of the research in my lab is to understand the basis of inheritance in plants by studying the mechanisms of meiosis, particularly pairing of homologous chromosomes and meiotic recombination. Both pairing and recombination are critical for correct segregation of chromosomes into gametes. We want to understand these processes at the molecular level. This basic research will provide a platform for investigations on how meiotic processes can be modified to improve plant breeding methods.
When a new downy mildew disease began to destroy impatiens, the number one bedding plant, in the New York landscape in fall 2011, we began to work with plant producers and landscapers to ensure that they were all aware of the problem and understood the key facts of its biology—and what this new problem would mean for their businesses. We scheduled informational meetings, prepared fact sheets and a podcast and posted them online, talked to garden writers, wrote articles and gave presentations on the subject at horticultural conferences at the local, state and national levels.
We are developing algal bioenergy as both an alternative to fossil fuels and a source of energy for powering systems that remove carbon dioxide from the atmosphere, thus reducing the concentrations of heat-trapping gases in the atmosphere and decreasing ocean acidification. We are also investigating protein by-products as potential nutritional supplement in animal feeds.
Grower adoption of Cornell research-based recommendations including narrow plant spacing and alternative mulches dramatically reduce losses from bacterial bulb decay and increase profitability, thus sustaining the small-scale onion industry.
In this study, we attempt to identify the functions of compounds secreted by herbivorous insects that interact with plants. Herbivore-derived elicitors are specific compounds found in the foregut or saliva of plant-eating insects that trigger specific plant responses, such as increasing plant resistance to herbivory or otherwise changing the interaction of the plant with the insect community.
DairyFAST is a collaborative effort between the Cornell ProDairy program and the New York Farm Viability Institute.
Agriservice professionals play a key role in disseminating information to dairy producers. As farmers implement management practices and appropriate technology, they turn to agriservice professionals for information and advice. The DairyFAST program provides a cohesive professional development program for agriservice professionals to enable them to have a positive impact on their farm clientele.
Climate change and habitat loss are two of the most pressing environmental concerns of the 21st century, and there is a growing scientific consensus that they exert influences on bird populations at multiple scales, from local changes in population persistence to range-wide shifts in species distributions. Citizen Science data allow us to document exactly how species respond to these environmental changes throughout multiple regions and for many years.
