Alexis Y Dollion is a behavioral ecologist whose research focuses on animal color change and especially its use as a communication signal. He received his PhD in ecology, evolution and environmental biology from Université de Paris (France) where he investigated the evolution of chameleon color change and its use as a communication signal during the sexual selection, in both inter- and intrasexual selection, in the panther chameleon (Furcifer pardalis).
Dr. Dollion's current research at the McGraw lab (arrival Nov. 2020) aims to uncover the mechanisms and functions of turkey color change, using an interdisciplinary approach that combines animal behavior, physiology and image/video/color analyses.
Additionally to my research, I am also an instructor here at ASU for the course BIO494: Animal coloration. Here is a description of the course:
"Animal coloration has long captivated researchers from various fields of science, from behavioral ecology to optical and quantum physics. In recent decades, considerable advances have been made in our understanding of how and why animals are colorful, due to the development of new technologies and of novel theories and discoveries. This course will cover broad aspects of the definitions, measurements, production, perceptions, functions, and evolution of animal colors.
The courses will consist of online modules and content that you can take at your own pace. You are invited to send an email to the instructor with questions before and after modules, assignments, and exams. You can also get extra points for active and relevant participation! You will have one assignment in which you will be tasked to write a fictional research project proposal (yet realistic) tackling a topic linked to animal coloration. You can freely pick the topic of this proposal, as long as it is related to animal coloration and not already published or ongoing research. Halfway through the course, you will have to provide a literature review for your proposal. At the end of the course, you will submit your written proposal and prepare a short digital presentation of it for the instructor and class.
