The sensory representation of the external chemical world in the brain is a translation of chemical features into patterns of brain activity. It is the nature these patterns—how that are established by stimulant patterns, how they vary in a population, and ultimately how they interact with other brain functions, e.g. emotions (joy) or behavior (buying wine)—that is the object of our research. We study aroma perception in order to provide information about food composition to producers that will allow them to produce likable, healthy and more profitable products.

2013 to 2016

Investigating the impacts (alone, and combined) of high temperature and drought on corn production. This includes identifying possible management and breeding strategies to reduce or eliminate the negative impacts of these climate stresses on corn production.

2013 to 2018

The Hawaiian Islands support the greatest levels of biodiversity per unit area in the World. The geological history of the archipelago has allowed certain early colonizing groups to undergo adaptive radiations on successively emergent volcanic islands. I have been studying all of the estimated 425 native species of the beetle family Carabidae (predaceous carabid beetles), and have studied the patterns of extinction in various groups based on historical and present-day collections from the field. Recent collaboration with Dr.


The viticulture and enology steering committee created a quarterly electronic newsletter, Appellation Cornell, to provide in-depth research articles written for laypersons, as well as faculty profiles, student profiles, industry profiles, and brief articles to highlight research, extension, and teaching activities of Cornell's Viticulture and Enology Program to a national and international audience. In its first year, readership comprised 1000 to 1500 online subscribers in 45 states, three Canadian provinces, Europe, Australia, and New Zealand. Fifty articles were published in 2010.

2009 to 2012

Powdery mildew is one of the world's most destructive diseases of grapevines. We know that infection of grapevines occurs as soon as they begin to grow in spring, but epidemics seem to stall for about six weeks and go nowhere fast. We've found that it's our cold nights that are suppressing the disease. Two modes of action are suggested. First, cold nights stimulate a temporary defense response in the youngest, and ordinarily most-susceptible, leaves. Second, cold causes direct damage to the mildew colonies.


Approximately 70 million metric tons of apple fruit are produced annually worldwide in 90 countries. However, the diversity of production is low as > 60% of fruit (excluding China) is produced by as few as five cultivars: Golden Delicious, Delicious, Gala, Fuji and Granny Smith. Many factors may have contributed to such low diversity in apple production, but lacking of superior new apple varieties is clearly one of the major factors. Apple is a perennial woody species with a long juvenile phase before fruiting.


Effective waste management can turn unwanted waste products into resources and reduce disposal costs. Waste management is part of every industry, but a waste product produced by one business can be a resource to another. Residuals from animal, food and yard waste, as well as industrial and household waste, have the potential to be valuable in agriculture and horticulture production as erosion control and nutrient and carbon sources, and in energy production and other industrial processes.

2008 to 2012

Animals can modify their bodies and behavior in response to changes in the environment, including changes in the social environment. For example, animals can use one reproductive strategy when they are in relatively good condition (or high ranking), and another when they are in poor condition (or low ranking). This phenomenon raises a key question: What physiological mechanisms help an animal match its reproductive behavior to its environment? And how do they obtain and integrate information from the environment to do so?


Organic agriculture has come to the forefront as an important opportunity for all farm sectors, across the country. Through our efforts, we have increased the research and extension support of these producers. We have identified strategies and developed grower tools to improve production and reduce environmental impacts of organic vegetable, grain and dairy systems in the Northeast U.S. A new initiative has focused on understanding the community supported agriculture model for impacts on consumer behavior and health awareness.

2008 to 2020

The Naturalist Outreach Program sends Cornell undergraduates and graduate students to local classrooms and community groups to give free presentations about natural history, ecology and conservation. By presenting lively, STEM (Science, Technology, Engineering and Mathematics) presentations, the program helps open the world of backyard biology to young people, enrich local second-grade to high-school science instruction, and simultaneously train Cornell students to communicate effectively about science.
