LAUREN MILLER

Ph. D. student, Graduate Group in Ecology, University of California, Davis (2014-present)

B.A., Integrative Biology and Asian Studies, University of California, Berkeley (2012)

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.

SARAH FRIEDMAN

Ph. D. candidate, Graduate Group in Ecology, University of California, Davis (2015-present)

B.S., Aquatic and Fishery Sciences, University of Washington (2014)

Research Interests: I am broadly interested in the underlying ecological mechanisms that shape the macroevolution of marine fishes. My previous research has focused on morphological convergence and constraint in planktivorous fish. More recently, my work combines aspects from biomechanics, functional morphology, phylogenetics, and comparative methods to lend insight into the selective pressures driving morphological diversification.

Postdoctoral researcher, Department of Evolution and Ecology, University of
California, Davis (2014-present)

Ph.D., James Cook University, Australia (Nov 2014)

M.App.Sc. James Cook University, Australia (Dec 2008)

B.Sc., University of Miami (Dec 2005)

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.

CHRISTOPHER MARTINEZ

Postdoctoral Fellow, Department of Evolution and Ecology, University of California, Davis (2016-present)

Postdoctoral Fellow, American Museum of Natural History, New York (2014-2016)

Ph.D., Stony Brook University, New York (Dec 2014)

B.A., University of California, Santa Barbara (June 2006)

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.

ANTHONY BARLEY

Postdoctoral research affiliate, Department of Evolution and Ecology, University of California, Davis (2017–present)

Arnold O. Beckman Postdoctoral Fellow, Department of Biology, University of Hawaii (2014–present)

Ph.D., University of Kansas (May 2014)

B.S. California State University, Sacramento (May 2008)

Research Interests: I’m an evolutionary biologist with interests in genetics, field biology, and organismal biology. My research is focused around understanding the evolutionary processes that generate and maintain genetic and phenotypic diversity in natural populations, and across evolutionary timescales using phylogenetic and population genetic approaches. I primarily work on lizards, and my current research is focused on investigating patterns of hybridization in whiptail lizards in Mexico. I am also interested in how well phylogenetic models fit empirical genomic datasets and identifying the ways in which we can improve models to make the inferences we draw under them more reliable. As a member of the Wainwright lab, I’m looking forward to learning a bit more about fish and developing my comparative methods skills.

B.S., Lees McRae College, North Carolina (May 2009)

Research interests: I am interested in evolutionary ecology, particularly topics such as adaptive radiation, ecological opportunity, adaptive landscapes, morphological diversification and innovations. I mostly study cichlid fishes and their morphological and ecological diversity and test hypotheses about their adaptive radiation using geometric morphometrics within a comparative phylogenetic framework.

M.S. Ecology & Evolutionary Biology, University of Tennessee Knoxville (May 2014)

Research Interests: Lake Malawi cichlids have been studied extensively in an effort to elucidate the mechanisms underlying their adaptive radiation. Their diversification is proposed to have happened via processes such as habitat partitioning, trophic specialization, and sexual selection. However, in the rock-dwelling mbuna of Lake Malawi this divergence likely involves how and where species feed on algae within the rocky reefs they exclusively inhabit.
To better understand the mechanistic factors underlying evolution in Malawi cichlid fishes, I research the influence of micro-habitat partitioning and diversity of mbuna feeding kinematics during algae sequestration.
