研究领域

Our research concentrates on the discovery and characterization of marine organismal diversity and comparative studies of novel morphological systems in predatory eukaryotes (i.e., marine invertebrate zoology & protistology). We are fundamentally interested in the diversity and evolution of organisms and organismal traits, particularly features associated with feeding, locomotion and symbiotic interactions. By addressing specific hypotheses about character evolution using molecular phylogenetic methods, we study the key innovations and transformations associated with broad patterns of morphological change. This exploratory approach is motivated by the thrill of discovery, the beautiful and the bizarre, and the yearning to build a more comprehensive framework for understanding the interrelationships of life on Earth. The marine lineages we work on tend to be drop-dead gorgeous (or hideous), and reflect spectacular morphological diversity, such as meiofaunal & planktonic animals, euglenids, dinoflagellates, ciliates, & gregarine apicomplexans.
