Dan Baldassarre  

I grew up in central New York and received my bachelor’s degree from Syracuse University, where I studied fish behavior in Dr. Uy’s lab while he was on the faculty there. After graduating from SU, I spent five years chasing fairy-wrens through the Australian outback for my PhD research in Dr. Mike Webster’s lab at Cornell University. My dissertation focused on how diverging sexual signals affect the speciation process. This research combined detailed population monitoring and field experiments with lab-based genomic and paternity analyses. I was recently awarded a NSF Postdoctoral Research Fellowship in Biology, which brought me back to Dr. Uy’s lab, at the University of Miami. I will be studying the behavioral, ecological, and molecular basis of blood-feeding in the vampire finch. The vampire finch is a bizarre member the Darwin’s finch group in the Galápagos Islands that drinks the blood of large seabirds. I hope to discover the environmental conditions that favor this behavior, and the physiological adaptations that allow these birds to exploit this unique dietary resource.

Dan is now an Assistant Professor of Biology at SUNY Oswego.

Jaime Chaves  

I moved to the US from my home country Ecuador in 2002 to obtain my MS at San Francisco State University and PhD from University of California, Los Angeles, both degrees in Evolutionary Biology. I then moved to Las Vegas for a two-year postdoctoral work at UNLV to continue my work on avian phylogeography. My main interest is studying the mode and tempo of the diversification of Neotropical birds. My research uses sequence data to construct evolutionary trees and an array of phylogenetic statistical methods to test evolutionary and biogeographic hypotheses. Most of my research has focused on hummingbirds from South America, yellow warblers from the Galapagos Islands and most recently, the widely distributed house wren complex. My collaobration in the Uy lab uses new high-throughput DNA sequencing technologies to examine the evolutionary origin of species divergence in the iconic adaptive radiation of Darwin's finches from the Galapagos Islands.

Jaime is now an Assistant Professor at San Francisco State University.

Elizabeth Cooper  

I first became interested in speciation genetics while I was an undergraduate at Grinnell College, where I was involved in a project investigating the transition from outcrossing to selfing in the plant Clarkia xantiana and C. parviflora. After graduating from Grinnell in 2003 with a B.A. in Biology, I went on to work as a lab technician in Magnus Nordborg’s lab at the University of Southern California. Later, I became a graduate student in the same lab, and my dissertation research focused on using next generation sequencing technology to perform a whole genome scan for speciation genes in two varieties of flowering columbine: Aquilegia formosa and A. pubescens. I received my Ph.D. from USC in January 2011, and came to the University of Miami as a postdoc shortly thereafter. In the Uy lab, I am using RAD Illumina data to explore the genomics of speciation in island in flycatchers.

Liz is now an Assistant Professor at UNC Charlotte. She continues her collaboration with the Uy Lab on projects exploring the genomics of speciation in Tropical birds.

Winter Beckles Project: Signal evolution in Anolis lizard

My first opportunity to study tropical ecology came during a summer research trip to Costa Rica, where I studied bioacoustics and edge effects on the Chestnut-backed Antbird, Myrmeciza exsul. By the end of the summer I had fallen in love with the life and diversity of the rainforest, and developed a strong interest in tropical ecosystems. I spent the following year working in the lab of Dr. Kevin Omland at the University of Maryland, Baltimore County. In the Omland lab, I analyzed duet recordings of Venezuelan troupials, Icterus icterus, and eventually worked with a team to band and record more specimens at the Cabo Rojo National Wildlife Preserve in Cabo Rojo, Puerto Rico. I have since graduated from UMBC with a Bachelor’s degree in Biological Sciences, and joined the Uy Lab in 2013. For my dissertation project, I am taking advantage of the recent introduction of Anolis lizards to explore how animals adapt to urbanization or novel habitats.

Winter finished his PhD in 2020, and is now a Lecturer at the University of Miami

Sarah Cowles Project: Hybrid zone dynamics in Zosterops white-eyes

I attended Gustavus Adolphus College in southern MN for my undergraduate education, where I earned a B.A. degree with a double major in biology and math. I then joined Dr. Robert Gibson’s lab at the University of Nebraska-Lincoln, where I obtained my M.S. degree in biology. My M.S. research project examined the trade-offs in behavior faced by males in lekking systems, both empirically through a field study of sharp-tailed grouse (Tympanuchus phasianellus) as well as theoretically by building a stochastic-dynamic programming model. Between degree programs, I’ve also had the opportunity to work on field projects investigating the sexual selection dynamics of Phylloscopus warblers in the Altai region of Siberia and species recognition in golden-crowned and white-crowned sparrows in southern Alaska. I then joined the Uy lab in the fall of 2013 as a Ph.D. student. The overarching goal for my dissertation project is to use a combination of fieldwork, genetic, and theoretical modeling techniques to examine the behavioral mechanisms contributing to speciation in a tropical avian system.

Sarah completed her PhD in 2019, and currently works at Northwestern University as a grants administrator.

Jorge Luis Hurtado-Gonzales Project: Color polymorphism in a live-bearing fish

A still unresolved question in evolutionary biology is how genetic variation is maintained in natural populations. In Poecilia parae, the Guyanese pentamorphic livebearer, there are five genetically-based male color morphs: two with carotenoid-based colors (red and yellow), one with structural color (blue), one with elaborate dorsal fins and vertical strips, and one resembling juvenile females.

My dissertation focused on understanding the maintenance of genetic color polymorphism among males in P. parae. I investigated how behavioral and ecological factors contribute to the persistence of such polymorphism in natural populations. Jorge defended his dissertation in May 2011, then joined Mikal Polak's lab as postdoctoral researcher at the University of Cincinnati. Jorge is now a permanent Physical Scientist for Environment and Climate Change, Canada.

Diego Ocampo   Project: Speciation in the variable seed-eater of Costa Rica

I received my BS and MS degrees in Biology at Universidad de Costa Rica. During those years, I had the opportunity to collaborate on several projects as a field and research assistant, and a curator of birds in UCR’s natural history collection. In addition, I joined an ornithological NGO, working on research and conservation in birds. Participation in these projects gave me the chance to work closely with Costa Rican avifauna, and so I developed a strong interest in Neotropical birds, mainly in understanding the evolutionary process that led to their diverse life forms and behaviors. My MS thesis project explored the ecology and evolution of relative brain size, as well as the size of specific regions of the brain, in hummingbirds. Hoping to further explore the evolution of birds, I joined the University of Miami as a PhD student in August 2016. Here at UM, I hope to explore the evolutionary and geographical processes that create and maintain bird species/forms, with a special focus on diversification of signals, such as courtship behavior and plumage color. Diego joined the department as a College of Arts and Science Rotation Fellow, and has received support from the American Ornithological Union and Smithsonian Institutes.

 
Deigo is now a postdoctoral research at LSU, continuing his work in the variable seed-eater with Nick Mason.

Emily Powell Project: Signal divergence and speciation in day geckos

A lifelong passion for nature led me to study biology at the University of Texas at Austin where I was able to work as a research aid to multiple evolution and behavior labs. I gained experience with data analysis and phylogenetics as well as with animal behavior. I completed genetic research on the diversification of Epipedobates poison frogs which later led to publication of a manuscript in collaboration with Becca Tarvin of Cannatella lab. I completed my bachelor of science in Ecology, Evolution, and Behavior and went on to intern for three months at the Chaparral Wildlife Management area where I learned valuable skills in field research such as mist netting, PIT tagging, and how to conduct species surveys. I also worked as a lab technician for an environmental lab and learned about quality control, lab safety, and how to use a wide range of equipment. I came to the the University of Miami to continue my education in the direction of evolutionary ecology. I am particularly interested in reptile and bird speciation with an emphasis on tropical and desert species.

 
Emily was supported by a University of Miami Graduate Fellowship. Emily is now a Lecturer at Texas State University, San Marcos.

Jelmer Poelstra Project: Population genetics of monarch flycatchers

I am a visitor from the Netherlands, where I grew up and also got my bachelor's degree (Univ. Groningen). I am interested in many aspects of evolutionary ecology, particularly speciation. For my Master's in Evolutionary Biology, still in Groningen, I first did a research project on grey-breasted wood-wrens with Hans Slabbekoorn (Univ. Leiden) & Caroline Dingle (Univ. Cambridge). I performed song playback experiments with two woodwren subspecies that show character displacement in song in their contact zone in Ecuador. At the Uy lab I am now doing my second research project for my Master's. Two morphologically distinct taxa of the chestnut-bellied monarch flyucatcher are basically inseparable on the basis of mitDNA sequences. With nuclear markers I hope to clarify this discrepancy.

 
After working wtih Al, Jelmer went tot Uppsala University to work on his Ph.D. in Hans Ellegren's lab.

Jason Sardell Project: Speciation in Myzomela honeyeaters

Upon receiving a B.S. in Mechanical Engineering from Worcester Polytechnic Institute, I worked for several years as a research analyst at a consulting firm in Cambridge, MA specializing in environmental economics and public policy.  During a 3 month sabbatical in the Neotropics, I became fascinated by the evolutionary causes of biodiversity, inspiring me to undergo a career switch in 2005 from a life in a climate-controlled office to that of a field biologist.  Since then, I have travelled around the world, conducting research on the population demography of Swainson's Warblers in the Mississippi Delta, breeding behavior of fairy-wrens in Western Australia, sexual selection among Phylloscopus warblers in the Indian Himalayas, population dynamics of song sparrows in Canada, breeding ecology of Amazona parrots and Aratinga parakeets in Argentina, conservation of harpy eagles in Panama, and metapopulation dynamics of Scottish water voles. I joined the Uy Lab as a PhD student in Aug 2011. For my dissertation project, I am examining the evolutionary mechanisms of speciation using the Myzomela honey-eaters of the Solomon Islands.

 
Jason finished in May 2016 and is now a postdoc in Mark Kirkpatrick's lab at UT Austin

Adam C. Stein Project: Avian hybrid zone dynamics

The diversity of life has always fascinated me. Since the age of 14, I have worked in zoological collections. This exposure led me to ponder the evolutionary processes that led to this diversity. My dissertation project focuses on speciation in bearded manakins of Central America. In particular, I wish to understand the role of divergent natural and sexual selection in rapid speciation.

Prior to joining the lab, I received a B.S. in zoology from Northern Arizona University, where I worked with Dr. Russell P. Balda on exploring the spatial memory abilities of Corvids. After my undergraduate degree (1999), I joined several field projects in Arizona, Australia, and South & Central America.

 

Adam defended his Ph.D. dissertation in Jan. 2009. He worked as a resident Biologist at the Muraviovka Park for Sustainable Land Use in Siberia, and now faculty at the International Educational Exchange.

Doug Weidemann Project: Speciation in Melanesian fantails

As a kid, I spent 11 years living in Guam and the Philippines and consequently became addicted to tropical and Old World birds. I got my undergraduate education at Pacific Union College in northern California, graduating with a B.S. in Biology and a minor in mathematics. While in California, I spent most of my free time studying waterbird ecology, although I also worked on topics as varied as human-bird interactions and hybridization in Butorides herons. Having had enough of the cold, temperate California climate, in August 2012 I joined the Uy lab at the University of Miami with the hope of returning to Asia/Oceania to study avian speciation.

Doug successfully defended his MS thesis in the Summer of 2015.

Ellen Wisner Project: Urbanization and animal communication
I received my B.S. degree in Biology from Centre College (Danville KY) in May 2002. During my time at Centre College, I had the opportunity to conduct research with Dr. Robert Ziemba on the hybrid zone dynamics and mating behavior of two local crayfish species (Orconectes juvenilis and Orconectes cristavarius). It was because of this research that I became interested in behavioral ecology and sexual selection. Since joining the Uy lab, I have developed and begun working on a new project testing how humans affect communication systems in animals. More specifically I am looking at how human disturbances affects signals used in mate choice and territory defense in birds. Ellen defended her dissertation in May 2011 and is now a Lecturer at UNC Chartlotte.
