My research focuses on plant-herbivore and predator-prey interactions, with an emphasis on the feeding behavior, chemical ecology, and nutrition of marine invertebrates. I am interested in marine ecological and evolutionary processes at various levels of organization and have studied organisms ranging from microalgae to fishes. My students use a variety of techniques in the field and lab, including:

  • Natural history observations and field surveys
  • Manipulative experiments on feeding behavior and fitness
  • Quantification of prey nutritional, chemical and structural properties
  • Molecular barcoding and phylogenetic techniques
  • Ethograms and video capture
  • Taxonomy and morphology

These studies have been conducted in diverse ecosystems, including the North Atlantic, the Chesapeake Bay, the Mediterranean Sea, the tropical Pacific, South Australia, the Red Sea, the Caribbean, brackish lakes in Egypt, and the South African intertidal.

Over the past 15 years, I have taught a variety of courses in ecology, marine sciences, zoology, and general science at both undergraduate and graduate levels. After several years as faculty in the USA, the Middle East and Southeast Asia, I joined UVI in 2014.

While my research has specific areas of emphasis, I am willing to accommodate new lines of ecological research that interest undergraduate and graduate students who work with me. Some of the works published include:
