I am a PhD candidate at the University of Virginia broadly interested in evolution.
I use lizards and melanin to study the evolution of hormonally mediated phenotypic development.
July 2022 Tyler Wittman's new paper "Experimental removal of nematode parasites increases growth, sprint speed, and mating success in Anolis sagrei lizards" was accepted in Journal of Experimental Zoology Part A! Read about the work here.
June 2022 I gave a talk, " Sexually dimorphic coloration evolves through alterations to hormonally mediated gene expression in Sceloporus lizards", at Evolution.
Our new paper, entitled "Evolution of hormone-phenotype couplings and hormone-genome interactions" was accepted in Hormones and Behavior! Check it out here.
May 2022 Our latest paper, led by Matthew Hale, was accepted in Frontiers in Physiology as part of a special issue, "exploring phenotypic diversity in ectothermic reptiles and in birds: developmental physiology throughout the lifespan and across scales"!
January 2022 SICB in Phoenix was excellent! Thank you, conference organizers, for making a safe and exciting conference. See you next year in Austin!
May 2021 Check out my blog post detailing my grant funded by the AGA!
Our new paper "Hormonal pleiotropy structures genetic covariance" has been accepted in Evolution Letters!
April 2021My paper with Stacey Lance and Matt Gifford correlating ventral coloration with apparent survival and reproductive success in the prairie lizard was accepted for publication in Journal of Zoology! This was the last chapter of my Masters thesis and finishes up my work with the wonderful prairie lizard. I was awarded an NSF Research Traineeship through UVA's EXPAND program that is designed to "reintegrate the phenotype"! For this fellowship, I am co-advised by Bob Cox and Dave Parichy to help address evolutionary patterns at the phenotypic, physiological, cellular, and transcriptomic levels. I am excited to continue my work understanding how Sceloporus lizards can evolve different patterns of sexual coloration so quickly!
March 2021 I was awarded an Evolutionary, Ecological, and Conservation Genomics Research Award from the American Genetics Association to help collect data for my dissertation!
April 2020I passed my qualifying exam!
January 2020 Another SICB is in the books! This year I received a Grant in Aid of Research from the Society!
