Dr. Ptacek was the invited Keynote Speaker at the 2015 annual meeting of the Southeastern Population Ecology and Evolutionary Genetics group, presenting ""Going Your Own Way: local adaptation despite gene flow in waterfall climbing gobies of the Hawaiian Islands." She is organizing a symposium at the Animal Behavior Society annual meeting entitled "New Frontiers in Animal Communication: In Honor of H. Carl Gerhardt" in July, 2016.
Dr Ptacek studies the evolution of mating signals and locally adaptive traits in a variety of fish species to better understand the mechanisms of divergence and speciation
Extension and Outreach
Dr. Ptacek is involved in K-12 Science Teacher training in evolution and genetics.
