My research develops mathematical models that might be used to improve the management of fishery, forest, and water resources or the dynamic control of pests or disease.
We oversee coordination of subcontracted partner institutions on various continents to screen wheat germplasm for resistance to the Ug99 race of black stem rust, discover and deploy new sources of genetic resistance through varietal development, and the multiplication and popularization of these durably resistant varieties to the benefit of small shareholder farmers and urban poor in developing countries of the world.
Pathogenic organisms such as Escherichia coli and Cryptosporidium parvum continue to cause a threat to our food and water safety. Similarly, organisms such as Dengue virus and rotavirus are important clinical analytes related to human health, especially in the countries of the developing world. Organisms such as Bacillus anthracis and Yersinia pestis are serious threat agents for our safety and security, since they can be used as bioweapon material.
We are concerned with the isolation and characterization of chemicals used as communicative signals by insects--substances that mediate courtship and reproduction activities or provide defense against predators, parasites, and pathogens.
We are designing, synthesizing, and applying new materials and properties for nanotechnological, biological, and biomedical applications. Our research has resulted in numerous peer-reviewed papers in high-impact journals such as Nature biotechnology, Nature Materials, Nature Nanotechnology, etc. More than a dozen patents have also been granted or filed. Some of these patents have been licensed to a local start-up company.
My early work in the environment revealed that traditional economic models failed to explain behavior around Superfund sites and the extreme reluctance to make trade-offs involving environmental assets. These problems pushed me into asking basic questions in a controlled laboratory environment in collaboration with colleagues from psychology.
Secondary students, including those in agricultural science education, struggle with various forms of literacy. Agricultural science teachers may be best positioned to assist students with applications of textual and scientific literacy applications in agricultural education. Through research, teaching, and professional development outreach activities, faculty at Cornell University are aiding in the development and implementation of research-based instructional methods to help all students succeed in applications of agricultural and scientific literacy.
We are creating new materials and approaches for promoting collaborative instructional programs and research projects that will effectively address the growing worldwide challenge to develop new food and fiber production systems that also maintain healthy ecosystems and viable rural livelihoods. An Internet-based platform has been designed that efficiently and effectively connects students, researchers, and practitioners to examine case studies of "real-world" conservation and sustainable development issues.
Three 3-year fellowships will help train plant breeders to use modern techniques to improve the abundance and safety of the U.S. food supply in a sustainable way.
This partnership employed a systems-oriented program of training and decision support to the ruminant livestock industry aimed at improving productivity, profitability and rural incomes in the Gulf of Mexico region. A fundamental goal was to enhance professional capacity to assess and act upon technology, market, and policy changes. Efforts included developing an internet-based platform of teaching, research and communication for training a mixed cadre of Mexican and Cornell students.
