I am a 6th year PhD student in Dr. Trevor Price’s lab at the University of Chicago. My research focuses on causes of variation in sexually selected traits from the perspective of signal evolution, function, and design.


I am interested in how the strength and direction of sexual selection on different traits varies in different habitats; how variation in selection pressures translates to (co)variation in the expression of sexually selected traits; and how variation in the sexually selected phenotype can ultimately lead to speciation. I address these broad questions in two species of Asian warblers: the Greenish warbler (Phylloscopus trochiloides) and Hume’s warbler (Phylloscopus humei). I conduct fieldwork in Central Asia to study the function of, and sources of variation in, sexually selected traits both within and between populations. I also use long term datasets in the Price lab to address the causes of temporal variation in population trait means. Read more...
