Clifton Ragsdale

Clifton Ragsdale is a Professor in the Department of Neurobiology at the University of Chicago. His research focuses on evolutionary biology of brain organization, particularly in cephalopods and the neocortex. The Ragsdale Laboratory combines genomics, molecular cell biology, and genetic manipulation to study evolutionary novelties in octopuses, including their immense nervous system, prehensile arms, and adaptive coloration system.

• Current research areas: comparative cephalopod genomics, octopus arm regeneration, nervous system organization, neuroendocrinology of octopus reproduction/death, and evolutionary developmental neurobiology of the neocortex.

The lab's 2015 Nature publication on the Octopus bimaculoides genome (with UC-Berkeley) remains a landmark study with 225 citations. Recent NIH-funded work explores octopus motor control, steroid hormone regulation of maternal behavior, and neuronal segmentation in cephalopod arms. Publications span journals like Nature Communications, Science, and Current Biology, emphasizing evolutionary neuroscience and developmental mechanisms.

Key research trends include: cephalopod genome analysis, neuroendocrine systems, regenerative medicine, comparative neuroanatomy, and evolution of neural complexity. The lab maintains active scientific engagement through Twitter and collaborative networks in evolutionary biology, neurogenetics, and developmental neuroscience.

• NIH grants: R03HD064887 (2013-2015), R03HD056094 (2008-2010), R01EY016838 (2006-2011), R01NS035680 (1998-2006)

Lab members include co-authors like Caroline Albertin and Joshua Rosenthal, with physical neighbors and collaborators at the University of Chicago. Altmetric scores indicate significant media coverage and academic discussion, particularly for studies on octopus regeneration and neocortex evolution.
