Sanna Koskela is a postdoctoral researcher at the Reiser Lab and studies the neural basis of motion vision behaviors using electrophysiology and behavioral experiments. Sanna has a deep interest in vision research and integrative, circuits-to-behavior neuroscience. She is especially interested in the interactions of physiology and environment across different scales, for example, how an animal's internal state affects its sensory tuning capacities.
Sanna studied biology at the University of Eastern Finland, with a Master's thesis project on the parental effects on offspring viability on brown trout. However, after a summer spent in the Lund Vision Group conducting behavioral experiments on bumblebees, she got fascinated by how remarkable the eye and the retina are and went on to study neuroscience at the University of Helsinki. In her Ph.D. research, she investigated sparse signal detection from single retinal neurons to behavioral performance in mice and frogs. She discovered, for example, how mice can utilize a different behavioral strategy at night than at day in a dim-light detection task, leading to strikingly better performance during the night.
Sanna is also passionate about scientific community building and likes to organize events, for example the MCN Janelia Philosophy of Science book club.
