Understanding why animals behave as they do is among biology’s most challenging problems. Research in animal behavior focuses on new insights into longstanding questions, such as why some males are more attractive to females than others, as well as on provocative new questions, such as how differences in the social environment experienced by individuals in the same population maintain genetic variation for behavioral patterns. The power of technology has enabled behavioral biologists to explore both traditional and newer questions as never before, from using genetic methods to diagnose mating success to manipulating the endocrine environment within an individual to understand cause and effect relationships between hormones and behavior to employing computational analyses of video recordings to discern subtle variations in the social interactions expressed in groups with different mixtures of behavioral phenotypes.
Most animals, including humans, need to sleep and eat. Being able to do so is critical for survival. What are the genetic and neural mechanisms that regulate these behaviors and how do they change with age? Our lab investigates these questions using the fruit fly, Drosophila, where genes are easy to manipulate. We use multiple approaches, including genetic screening, behavioral analysis, genomics, and brain imaging techniques in this accessible model system with the goal of uncovering fundamental principles that regulate behavior.
My research combines ecological and evolutionary principles to study the population biology of coastal marine invertebrates. One main focus is on the evolution of dispersal, reproductive strategies, and life histories. Another main focus is on the ecology and evolution of cryptic species of corals in the genus Pocillopora. We typically use some combination of field and laboratory experiments, population, quantitative, and molecular genetics, and mathematical modeling/theory.
I use mathematical models to explore how adaptation and species interactions drive patterns observed across communities. Much of my past work has focused on predator-prey, host-pathogen, and other exploiter-victim systems.
My lab group investigates the social behavior of wild birds. We study how social groups form, the selective forces that influence cooperation, and the fitness effects of complex behaviors. Our work analyzes detailed long-term field data on behavior and genetic reproductive success, using statistical models to quantify within- and between-individual effects. Major study systems include Lance-tailed Manakins in Panama and Brown-headed Nuthatches in the Tallahassee area.
The goal of my research program is to gain insight into the process of speciation in order to understand the origin of biodiversity. I employ an integrative approach to studying speciation, which involves several fields of biology, including behavioral ecology, evolutionary neuroscience, phylogenetics, population genetics, genomics, and ecology.
Much of my research has involved underwater technology, manipulative field experiments, and mesocosms to study the Caribbean spiny lobster.
