The Poplawski lab focuses on the development of regenerative and diagnostic strategies for neurodegenerative diseases. Our main focus is to enhance nerve regeneration following spinal cord injury via two strategies: (1) cell therapies within the injured spinal cord and (2) gene therapies within the motor cortex in the brain. In a second line of research, we seek to develop assays that can accurately diagnose the severity of acute and chronic injuries to the brain, specifically dementia and neurotrauma.
Dr. Gunnar Poplawski specializes in neurodegenerative disorders, using a multifaceted approach to investigate regenerative strategies for CNS injury and biomarker discovery for neurodegenerative disorders. His research centers on disorders such as dementia - including Alzheimer’s disease - and neurotrauma - including spinal cord injury - for which he seeks to develop therapies and utilize assays to help determine the severity of such conditions.
Poplawski joins the Cleveland Clinic after spending time in Singapore, during which he completed fellowships at both Duke-NUS Medical School and the National University of Singapore (NUS). He received his PhD from the University of California Department of Biology and went on to complete his postdoctoral fellowship at the University of California San Diego (UCSD) in the Center for Neural Repair, under the guise of Professor Mark Tuszynski, MD, PhD. Poplawski has also published in high impact journals such as Nature, Science Translational Medicine, and Neuron.

Awards & Honors
The Poplawski lab focuses on developing therapies that can help patients with spinal cord injuries to regain mobility after suffering from paralysis. We use both cell culture and mouse models to discover mechanisms that could be beneficial for such patients; more specifically, we attempt to identify mechanisms that promote the regeneration of injured nerve fibers.
Our work centers around three main areas:
Investigating these areas will help us to bridge spinal cord injury sites with the help of cellular grafts, establishing a patient’s functional recovery from injury.
