I study plant-insect interactions from molecules to ecosystems. I am an integrative and comparative biologist with an interest in the chemical senses. Everything begins with natural history.

Research Focus

Floral scent, the focus of my research, is a key sensory component of plant-pollinator communication, a poorly explored dimension of floral phenotype, and a major chemical expression of biological diversity. I work at the rich biological interface between insects and plants, an important source of terrestrial biodiversity and complex ecological interactions. To a great extent, this richness is manifested in chemistry: the chemistry of defense and resistance, of mimicry and deception, of communication between mutualists, and in physiology; the physiology of signal detection and processing, of sensory integration and its impact on behavior. My training in plant and insect biology reflects my commitment to understanding chemical communication from the standpoints of signal production and detection. Due to technological challenges and historical visual biases among pollination biologists, the study of floral scent remains a biological frontier with unlimited potential for novel research initiatives. During the past decade, I have dedicated myself to the goal of integrating floral scent into the field of pollination biology, through my own multidisciplinary studies and publication of several review papers, through training students and postdocs in volatile analysis and behavioral bioassays and through organizing and chairing the first Gordon Research Conference in my field.

Teaching Focus

My goals as an instructor are to nurture independent, critical thinking, to foster an appreciation for the process of science, and to empower students to direct their enthusiasm and interests toward productive educational experiences and careers. I respect diversity in the learning styles, opinions and backgrounds of my students, and I do not direct my teaching only to the most gifted or the most challenged students. In addition, I teach with multiple media and encourage my students to immerse themselves in their subject of study, through attending outside seminars, using the internet, relating course material to current events and interviewing other scientists engaged in that particular field of study. The energy and creativity that I have invested in my teaching activities has attracted many bright young students to my lab and revealed new, exciting directions for my research. My teaching at Cornell consists of lectures contributed to large undergraduate courses (BioNB2210 Intro to Animal Behavior; BioNB390 Chemical Ecology) to smaller topics courses (BioNB4200 Multimodal Communication), including a new course (BioNB 4460) on the subject of Plant Behavior.
