Hope through Rehabilitation & Research
Assistant Professor, Neurology and Neuroscience
Weill Cornell Medical College
My laboratory focuses on spinal cord injury (SCI) repair and the development of therapeutic interventions to promote recovery of function. Studies range from examining the basic biology of axonal regeneration to testing small molecules and cellular transplants for their ability to promote axonal regeneration and functional recovery in rodent models of spinal cord injury.
Caitlin Hill received her B.Sc.H. in biology from Queen’s University in Kingston Ontario Canada in 1994 and her M.Sc. in zoology and neuroscience from the University of Toronto in 1996. She then began to focus her research on axon regeneration and spinal cord injury repair. She trained in the laboratories of several prominent spinal cord injury researchers including the laboratories of: Dr. Geoffrey Raisman at the National Institute for Medical Research in Mill Hill, London; Drs. Michael Beattie and Jacqueline Bresnahan at The Ohio State University, where she completed her Ph.D. in Neuroscience in 2002; and Drs. Patrick Wood and Mary Bartlett Bunge at the Miami Project to Cure Paralysis. During her time at the University of Miami she was also an Associate for the Christopher and Dana Reeve Foundation and a visiting scientist in Dr. Pate Skene’s laboratory at Duke University. In 2010 she moved to Burke to continue her research on spinal cord injury repair.

1. Testing therapeutic interventions in rodent models of SCI for their ability to enhance axonal regeneration and behavioral recovery. This research emphasizes the testing of small molecules with known cellular functions and the use of cellular transplantation with an focus on strategies that can be translated to the clinic.
2. Understanding the basic biology behind dystrophic axonal endings (retraction bulbs) that form when injured axons encounter the chronic lesion margin. These studies examine the influence of protein and mRNA synthesis, transport and degradation in the formation of dystrophic axonal endings. By understanding the basic biology of dystrophic endings we aim to develop strategies to enhance the regrowth of chronically injured axons.
3. Development of strategies to enhance the survival of transplanted cells, with a particular focus on Schwann cells (SCs) because of their potential for autologous use. These studies aim to address the extent to which activation of adaptive homeostatic pathways in SCs prior to transplantation enhances transplant survival, and whether improving survival results in functional improvements.
