Ryan Maloney
Assistant Professor
Ryan Maloney graduated from Brandeis University in 2011 with degrees in Biology and Neuroscience, where he studied the effects of neuropeptides on rhythmic muscle activity in the crustacean stomach with Eve Marder. He completed his Ph.D. at Brown University, where worked in the lab of David Berson to understand the input of intrinsically photosensitive Retinal Ganglion Cells (ipRGCs) to the dorsal lateral geniculate nucleus, studying the role these luminance sensing cells play in our ability to perceive brightness. After a short postdoc with Matt Pecot at Harvard Medical School studying the development of the fruit fly visual system in Drosophila melanogaster, he moved to Ben de Bivort’s lab at Harvard University to study idiosyncratic individual preferences in Drosophila, where he was awarded the Harvard Brain Institutes Postdoctoral Pioneer grant.
Ryan joined Colorado College in 2024 as an Assistant Professor.

First Year at Colorado College: 2024
Research Interests
What makes one individual different from another? Ryan’s interests center on this basic question, using the fruit fly Drosophila melanogaster to understand what factors lead individual flies, even with identical genetics and environmental backgrounds, to have different behaviors. Ryan’s lab investigates this using high throughput behavioral screening, genetic and pharmacological manipulations and a focus on the neural circuits underlying behavior.
