KATHERINE CORN

Ph.D. Candidate, Graduate Group in Population Biology, University of California, Davis (2016-present)

B.S., Ecology & Evolutionary Biology, Cornell University (2016)
A.A., Bard College at Simon’s Rock (2013)

Research Interests: I’m interested in how functional morphology affects macroevolutionary processes. My dissertation work focuses on the effect of feeding mode on the functional and morphological diversification of coral reef fishes. I use phylogenetic comparative methods, geometric morphometrics, linkage modeling, and field-based videography. My previous research at Friday Harbor Labs was on shark tooth cutting ability and burial mechanics in flatfishes.

ALEXUS ROBERTS 

Ph.D. Candidate, Graduate Group in Population Biology, University of California, Davis (2017-present)

B.S., Ecology, Evolution, and Environmental Sciences, Purdue University (2017)

Research Interests: I am interested in exploring the evolution of biomechanical processes in fish systems. More specifically, I am interested in using morphological data, ecomorphology, phylogenetics, and comparative methods to understand the diversification and potential constraints placed on functional mechanisms in closely related species. My previous research focused on the role of evolutionary integration in the diversification of the lower jaw adduction system in sculpins and related species. As a member of the Wainwright lab, I hope to expand my skills to understand more about morphological variation and movement across fish lineages.

DARIEN SATTERFIELD

Ph.D. Student, Graduate Group in Population Biology, University of California, Davis (2019-present)

M.S., Biology, California State University, Long Beach (2019)
B.S., Biology – Marine option, California State University, Northridge (2015)

Research Interests: I am interested in the relationships among morphological diversity and behavioral ecology in fishes. Specifically, I would like to address the ways in which morphology limits technique in feeding, swimming, and other behaviors. During my undergraduate research I focused primarily on the relationship among size and courtship and feeding behaviors in fish, and my masters thesis addressed local adaptation in behavior as a product of geographic isolation and spatial variation in fishing pressure among populations. I think that now it would be interesting to measure how morphological and behavior correlations may be impacted by selective pressures such as fishing which vary over space.

NICHOLAS PEOPLES

Ph.D. Student, Graduate Group in Population Biology, University of California, Davis (2021-present)

M.S., Biology (Ecology, Behavior, Evolution), Boston University (2021)
B.S., Environmental Sciences, Duke University (2020)

Research Interests: I am interested in exploring the evolution of jaws and teeth in fishes. More specifically, I am interested in combining ecological, morphometric, and genomic data to explore trophic diversification in adaptive radiations. I have a particular interest in the haplochromine cichlids of Lake Victoria. As a member of the Wainwright lab, I hope to learn more about macroevolutionary patterns and explore new ways to quantify fish tooth traits such as shape.

KHALIL RUSSELL

Ph.D. Student, Graduate Group in Population Biology, University of California, Davis (2021-present)

B.S., Biology, College of William & Mary (2021)

Research Interests: I am interested in the relationship between morphology and ecology, the role of phenotypic plasticity in this relationship, and how it relates to outcomes of species introductions. I am particularly fascinated by the remarkable morphological plasticity, history of rapid speciation, and widespread invasive success of the family Cichlidae. My undergraduate work examined morphological differences between native and introduced cichlid populations using geometric morphometric methods. In the future, I would like to explore variation in morphological plasticity among fish families and its potential role in adaptive radiations and in determining invasive success.

Postdoctoral Researchers

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.

DYLAN WAINWRIGHT

Postdoctoral research affiliate, Department of Evolution and Ecology, University of California, Davis (2021–present)

NSF Postdoctoral Fellow, Department of Ecology and Evolutionary Biology, Yale University (2019–present)

Ph.D., Harvard University (2019)

B.S., Duke University (2012)

Research Interests: My work lies within the overlapping space of experimental biomechanics, functional morphology, and comparative biology, and I have an overall goal of understanding connections between organismal form and function to better understand evolutionary processes and generate new ideas for engineering. More specifically, most of my work has focused on the surfaces of fishes and other aquatic organisms in an attempt to understand why fish surfaces are so diverse and how surface structure changes performance. Currently, I’m excited about studying evolutionary patterns of surface morphology in fishes, but I’m also looking beyond surfaces to work some on both feeding and locomotor systems in fishes.
