My research focuses on present-day challenges facing agriculture, such as climate change, environmental degradation, land grabbing, and conversion of crop land to fuel production.
I work on developing communication strategies for the SRI-Rice Center at Cornell University and on implementing knowledge-sharing efforts that serve global communities involved with the system of rice intensification (SRI) and conservation agriculture (CA). Specifically, I design and manage the SRI and CA websites and associated social media, facilitate links among international, national and topical SRI networks, and develop databases and platforms for sharing research related to SRI, CA and related systems of crop intensification.
More than half of the world's population depends on rice as their staple food, and the U.S. is the world's fourth largest exporter of this essential commodity. Rice production must increase dramatically and in a sustainable manner to meet the demands of the 21st century. Population pressure, natural resource limitations, changing climate and globalized markets all contribute to the rapidly evolving landscape of agriculture and underscore the importance of agricultural innovation. Advances in genomic science offer new opportunities to address many of the challenges for the future.
The project is focused on the safe and effective development and commercialization of bio-engineered crops in developing countries.
Cornell NutritionWorks, at www.nutritionworks.cornell.edu, is an interactive, continuing professional education program for nutrition and health practitioners developed by the Division of Nutritional Sciences. One offering is a six-week, in-depth online course, "Preventing Childhood Obesity: An Ecological Approach." Evaluation results show the course leads to improved knowledge, skills, and confidence in addressing childhood obesity immediately following the course, with application of that knowledge and skills six months later.
eClips is a digital database of 10,000 clips and more than 40 podcasts, focused on entrepreneurship, business, and leadership. The material is based on hundreds of in-depth interviews as well as business presentations. eClips makes it possible for business people (including small business owners and entrepreneurs), educators, and students to find targeted and focused information, because it is organized by entrepreneur, company, demographics, topics, and keywords.
Plant viruses invade a susceptible host to cause disease by transporting their genomes across the barrier of the plant cell wall. Doing this requires a unique class of proteins made by the virus, termed movement proteins. This process serves as a model for the transport of molecular complexes between plant cells and hence for the mechanism of cell-cell communication in plants.
Mobile phones are increasingly ubiquitous in many parts of the world today, with an estimated 4 billion subscribers worldwide. The mobile phone, however, is not just a device for calling but is also converging with other information technologies. With such widespread adoption and convergence, it is important to understand how these technologies are being used and integrated into society. The rise of mobile technology has accompanied the rise of social networking technology on the Internet. These social media provide new means for people to maintain and even create social ties.
The overall project deals with the phenomenon of polyploidy (whole genome duplication), which is a major force in the evolution of wild and domesticated plant species.
