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.


As water becomes a limiting resource worldwide, producers of floriculture crops are under increasing pressure to reduce water consumption or adapt to using poorer quality (saline) water sources. Many floriculture species are sensitive to salt accumulation in the root zone.

2008 to 2010

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.


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.

2007 to 2015

My laboratory studies the enzymology of plant cell-wall degradation with a major focus on cellulases. Enzymes that degrade insoluble substrates have important differences from most enzymes, whose substrates are small, soluble molecules. In addition, cellulases are important industrial enzymes and have potential in the production of renewable, nonpolluting fuels and chemicals. We are using a combination of genomics, protein engineering, and molecular biology in our research to produce cellulases with higher activity on pretreated biomass materials.

2007 to 2012

Asia post-Green Revolution required new management systems to improve productivity, increase the efficiency of natural resources (water, land and inputs), improve farmer income and minimize environmental impact. This was accomplished by introducing farmers to Conservation Agriculture (CA) where soil disturbance is minimized and permanent soil cover is promoted.


Water is a limited resource with increasing multi-purpose uses. Rice production uses more water than any other crop. Means are being sought to get "more crop per drop". Among practices being examined are aerobic rice, alternating wetting and drying and the System of Rice Intensification. We are working to understand changes that occur in the rice rhizosphere during periods of wetting and drying and how these changes affect nutrient availability and retention, greenhouse gas emissions, and crop yield.

2007 to 2010

Heavy metal detoxification in cells is contingent upon chelation of heavy metals within the cytosol by specific cellular ligands and transport of ligand-metal complexes, either across plasma membranes (elimination) or across intracellular membranes (sequestration and compartmentation). We aim to identify the transport proteins in the model plant Arabidopsis thaliana that are responsible for the sequestration of heavy metals and their chelates into a specific subcellular compartment, the vacuole.


Fruit farmers and turfgrass managers must produce pesticide and fertilizer records on demand for EPA Worker Protection, NYS Dept. of Environmental Conservation, food safety audits, food processors, produce brokers, eco-markets, organic certifiers, etc. Trac Software has been documented to improve pesticide application record keeping and to facilitate generating reports. Since its invention in 2003 by Juliet Carroll, NYS IPM Program, over 500 fruit farmers in New York and worldwide have obtained Trac Software, and 98 percent continue using it.

2002 to 2008

The South Asia Program uses the funds awarded by the U.S. Department of Education to support a variety of research and outreach activities related to South Asia. In particular, it supports graduate students wishing to work on and in South Asia, supports active collaboration between researchers on South Asia in the Central New York area, and disseminates information on South Asia to the schools and local community at a time when intercultural understanding needs fresh impetus.
