Research Interests: I am broadly interested in using phylogenetic and functional morphological approaches to understand the patterns and processes shaping the remarkable diversity of fishes. My current focus is on the Syngnathiformes (e.g. seahorses and pipefish), a group of fishes with unusual and novel modes of locomotion, reproduction, and feeding. Recent work in other labs has indicated that seahorses and pipefish feed using an elastic recoil mechanism. As part of my dissertation, I plan to investigate this feeding mechanism in more detail and to characterize its phylogenetic distribution in order to understand the evolution of this functional innovation and how it has shaped the evolutionary history of the Syngnathiformes. I am also interested in studying the interplay between functional innovation and functional constraint and how both affect morphological and lineage diversification rates. A well-resolved phylogeny is essential for asking macroevolutionary questions about syngnathiform evolution, and therefore an important component of my research is the construction of phylogenetic trees using cutting-edge methods.

In broad terms, I am interested in studying ecomorphology, adaptive radiations and convergent evolution by integrating molecular phylogenies, morphological data and fossil information; this approach can provide key insights into evolutionary processes and potentially deterministic aspects of phenotypic evolution. Currently, I am interested in examining how predation risk, habitat type, and prey choice have affected the morphology and evolutionary history of Cancridae crabs and how claw dimorphism relates to the breadth of a crab species’ diet.

Research Interests: I am interested in using a combination of genetic and
morphometric evidence to explore the mechanisms behind macroevolutionary processes witha particular focus on marine fish diversity. Currently, I am investigating morphological convergence in planktivorous acanthurids (surgeonfish) and the influence of fin spines on cyprinid (carp, minnow) body shape evolution.

Research Interests: I’m interested in using phylogenetics and biomechanics to explore fish performance and diversity, with particular focus on the relationship between evolution of functional traits and lineage diversification. I’m also interested in the role of functional integration and modularity in driving and constraining evolution of morphology.

Research interests: I seek to understand the fundamental processes driving large-scale macroevolutionary and macroecological patterns by utilising phylogenetic comparative methods. My previous research focused on mammalian evolution, in particular cetacean size and life history evolution as well as an ongoing collaborative project set on the evolution of mammalian dietary strategies. I also dabble in phylogenetics, in particular methods for combining previously published trees into new phylogenies (supertrees). In the Wainwright lab I am applying my skills to understanding the evolution of the labrid radiation from a morphological perspective and occasionally building molecular phylogenies.

Research interests: I am broadly interested in the chronology and biogeography of species diversification, and mechanisms that maintain species boundaries. My previous research has focused on the evolution of coral reef fish species, in particular the timing of extant species diversification in relation to biogeographical patterns, the identification of biogeographical barriers important in separating sister-species, and mapping geographical areas of overlap among sister-species. I am now applying my skills to understand the evolution and role of phenotypic traits in coral reef fishes.

Research Interests: My research concerns the diversity of fish forms and its implication for lifestyle variation. I am interested in understanding evolutionary processes involved in morphological diversification and the extent to which shape impacts function and performance. To this end, I have worked with a number of systems, from sexual dimorphism in skate pectoral fins to covariation of body and jaw shapes in cichlids. At UC Davis, I am using geometric morphometrics to study cranial kinesis in cichlid fishes as a novel way to understand their trophic evolution and niche segmentation.

Research interests: Actinopterygians have evolved numerous tooth shapes, and perhaps even more interesting, combined them in even more variations. Such morphological diversity prompts many interesting questions about how heterodonty (multiple types of teeth) has evolved from the ancestral homodont (one type of tooth) condition. In actinopterygians, the evolutionary relationships between heterodonts and homodonts remain relatively unexplored. I research the dentition of bony fishes to establish morphological information on combinations of different tooth types to understand the widespread evolutionary patterns that exist across and within different families. Furthermore, examining patterns of both tooth replacement and tooth attachment will enhance the overall understanding of the evolutionary history and ontogenetic development of both heterodont and homodont conditions.
