I am a behavioral biologist interested in fish behavior, currently studying the fascinating strategy of mate-choice copying. Here, individuals use public information from conspecifics to decide which mate to choose. I was part in developing "FishSim Animation Toolchain", a research tool for the creation, animation, and presentation of computer-animated fish stimuli for the use in behavioral experiments. The big advantages of using computer-animated stimuli in research are (1) the possibility for non-invasive manipulation of morphological and behavioral traits, and (2) the reduction of live test animals in experiments with regard to animal welfare.
