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.

2010 to 2011

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.


Research in my lab examines the functional significance of animals in aquatic ecosystems. This includes examining the consequence of species loss as well the addition of novel organisms through invasion. In addition, we are interested in how organisms interact with their environment in an evolutionary context.

2007 to 2012

The goal of the project is to build capacity in small- to medium-size firms in rural markets. Through applied research and capacity-building workshops, small agribusiness companies are targeted. Each component of the outreach and research program was evaluated. Workshops were consistently rated as highly effective, and the impacts of the program were measured by expanded sales and adoption of new technologies. Since the program begin in 2003, sales have steadily increased for the companies in the program/workshops. The outcomes of the programs have indicated the workshops are effective.


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.


Our consensus paper in Science projected that coral reefs will be unable to grow calcareous skeletons within the next 50 years due to rising carbon dioxide (acidification). Our research paper in PLoS Biology showed for the first time that increases in infectious coral disease can be driven by climate warming. This economically important ecosystem will be destroyed by a combination of warming and acidification in the next few decades.

2007 to 2013

We use the tools of molecular biology to document the biodiversity of birds and other animals and to explain their behaviors, ecologies and evolutionary histories. Our research program integrates studies of evolutionary trees (phylogenetics), speciation, hybridization, animal behavior, ecology, disease ecology and conservation genetics.


This project examines how recent declines in fertility in several African countries may affect the schooling of children and the inequalities in schooling among children.


Led by Dr. Peter Gregory of Cornell University, an agricultural biotechnology strategy was developed for, and adopted by, the East and Central African region. This work was conducted under the auspices of the Cornell/USAID Agricultural Biotechnology Support Project II (ABSPII) in close collaboration with the Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA) and their ten member countries. The strategy embraces both crops and livestock and includes a wide range of technologies.


The Cornell Ecoagriculture Working Group (EWG) in concert with Ecoagriculture Partners, an international nongovernmental organization, and a steering committee of 20 science, conservation, and rural development organizations has created the Landscape Measures Resource Center (LMRC) with support from four donors.
